During the four-day event the German-based manufacturer introduced three new models and a two concept vehicles.

BMW X4 (concept)

The first concept vehicle present the hatchback X4. Similar in both design and specs to the X3, it will be offered at around $70,000 and should come off the line sometime this spring.

BMW M6 Gran Coupe

BMW’s M6 Gran Coupe goes into production around the same time as the X4. The M6 shares the M3’s large air intakes, a low roof line–a bit deeper here–and a carbon fiber roof top. Unlike previous models, however, the M6 will have four doors instead of two and feature 20” wheels with gold caliper brakes.

The M6 comes equipped with the M3’s twin-turbo 4.4-litre V8 engine that is found under the bonnet of the M6 Coupe and the M5, and a seven-speed dual-clutch transmission.

BMW Z4 Roadster

Also present was the Z4 roadster, with a complete makeover.

Three metallic paint colors have been added with orange insert panels, stitching and a high-gloss trim on the gear lever. The Z4 range includes an entry-level 2.0-litre, four-cylinder engine that provides a maximum 300hp and 177lb-ft. of torque, coupled with a choice of a six-speed manual transmission and an optional eight-speed automatic transmission.

We can expect to see the Z4 off the line sometime this spring. Pricing details are not yet available.

BMW 4 Series Gran Coupe (concept)

But the big highlight was the BMW 4 Series Gran Coupe. Very few details are available outside of it’s design (previewed below), which is more tapered and sporty than the outgoing 3-series Coupe, predicting a M-Sport or Sport Line model. As yet, the M4 has no price tag; however, a representative suggested something in the ballpark of the outgoing 3-series price-tag at $62,295.

Beyond the NAIAS

Outside of AIAS, BMW has just launched the 2013 320i and made headlines with the announcement of a Z2.

The Z2 is BMW’s response to the new MX-5 Miata roadster, and and will likely be the same size as the Z3 in order to maintain crash test ratings. Early renderings suggest it will emulate the Z4’s design, but you’ll have to wait awhile for more details. The Z2 goes into production early 2015.

As far as we know, the 2015 BMW Z2 won’t have any game-changing innovations, although the magnesium engine block and driveshaft reported by Auto Bild would be remarkable for a lower-end sports car and a number of high-dollar rides too. [CG]

The 2013 320i sedan is now available now with a 2.0L Twin Power inline four cylinder engine with optional eight-speed manual or automatic transmission. The 320i promises 180 HP and is available now at $32,550 MSRP, packing heated seats, a heated steering wheel, rear-view camera and safety sensors, moon-roof, folding seats and optional iDrive navigation.

So, everyone in the Aurora Illinois area knows how great helium is – you know, party balloons, squeaky voices. But a lot of people around Aurora still haven’t heard about the benefits of nitrogen in your tires, and how it can help your tires. Here’s some great advice from AutoNetTV, brought to you by Sterling Automotive Repair.

Nitrogen has actually been around for a long time in the Aurora Illinois commercial sector, but it’s just starting to catch on for private vehicles in the 60504 zip code area.

Why nitrogen in your tires? Air is air, right? Actually, it turns out there is a difference.

The heart of the matter is maintaining proper tire inflation. When your tires are properly inflated, they last longer, handle better and more safely, and save you money at the gas pump.

The problem is that tires filled in Aurora with regular air can lose a pound and a half of air pressure every month. This just happens as the oxygen in the tire seeps out. So if you don’t check your pressure for a month or two, well, you can be significantly low – low enough to actually affect your handling, shorten tire life and waste money at the fuel pump.

How does nitrogen help? Regular air contains about 78% nitrogen. Nitrogen is the largest molecule in air. It’s dry and non-flammable. Air also contains 21% oxygen, which is smaller and seeps out of the tire three to four times faster than nitrogen.

So, a tire filled with nitrogen at Sterling Automotive Repair will take about six months to lose as much pressure as regular air does in just one month. So it’s more forgiving for those who don’t check their pressure every week.

Also, when oxygen is at higher temperatures – like those inside your tire when you’ve been driving for awhile – it oxidizes the inside of your tire. Getting the oxygen out of your tire means that it’ll last longer.

Who’s using nitrogen? Well, let’s start with NASCAR and Indy. These racers like nitrogen’s ability to maintain consistent tire pressure and reduce tire temperatures under very demanding conditions. The US government requires all commercial aircraft to have nitrogen in their tires. NASA and the US Military use nitrogen. The mining industry has been filling those “humongous” tires with nitrogen for years. And semi trucks and trailers are starting to use nitrogen extensively.

You may have heard some detractors of nitrogen. But the studies and white papers from tire and vehicle manufacturers demonstrate that the technology really works.

In fact, a prominent consumer research group did a study where they filled some tires with air and some with nitrogen and stacked them outside for a year. They observed that the nitrogen filled tires did hold their pressure better, but they couldn’t see the economic benefit. But that particular test has very little to do with the real world. Most tires are actually holding up cars and they also get driven around and do a lot of work. So if nitrogen helps them last longer, saves gas and gives safer handling, it’s worth considering.

With the recent focus in Plainfield on improving fuel economy, we’ve been told how important it is to maintain our tire pressure.

Everyone in Plainfield knows that tires wear out, but we all want to make them last as long as possible because they’re fairly expensive to replace. In addition to saving gas, properly inflated tires last longer. Under-inflated tires will wear out more quickly.

Some people in Plainfield wonder if there is benefit to adding a few extra pounds of pressure when they fill up their tires. But actually, there isn’t. In fact, there are very good reasons not to over-inflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling.

Every vehicle in the Plainfield area has a sticker on the driver’s side door jamb that tells you the manufacturer’s recommended tire pressure. This recommendation is an integral part of the vehicle’s suspension tuning. A lot of engineering actually goes into the recommended tire pressure, so it’s important to follow it.

What else do we need to know about tire maintenance? Tire rotation and balancing are very important. Let’s start with rotation. Because the front tires handle the brunt of turning forces, the shoulders of the front tires wear more quickly than the rear tires. We rotate the tires so that they all get to do some duty on the front and they’ll all wear evenly over their life.

For most vehicles, front tires are rotated to the rear and vice versa. Others recommend a cross rotational pattern. Some vehicles use an asymmetrical tire so those tires need to stay on either the right or left side – it’ll say which on the tire. Some high performance cars have asymmetrical tires and different sizes on the front and rear. These can’t be rotated at all. Your owner’s manual will have details for your car.

How often should you rotate your tires? Your owner’s manual will have a recommendation. Your service advisor at Sterling Automotive Repair can do a visual inspection to let you know if it looks like it should be done. The interval is typically around 5,000 miles.

You know, some people don’t think new tires need to be balanced. What they aren’t taking into account is the wheel. Between the wheel and the tire – even a new tire – there’s enough variation to require balancing.

When you add the valve stem and tire pressure monitoring sensors required on new cars, balancing is definitely in order. When a tire’s out of balance, it’s actually hopping down the road. You’ll feel the vibration through the steering wheel if a front tire’s out of balance and through your seat if it’s a rear tire.

Proper wheel balance promotes tire life and increases safety. Historically, lead weights have been attached to the wheel to bring it into balance. Lead gives some environmental concern, so steel weights are starting to be substituted.

Also, always use the same size tire on an axle. Different size tires on the front or on the back can lead to some real handling problems. And tire manufacturers recommend that when you get two new tires, they be installed on the rear because that’s where you need the most traction to avoid spinning-out.

You may know that most automotive failures in Aurora Illinois are tire related, but do you know the second most common cause for vehicle failure? Nope, it’s not teenagers. It is the coolant system. But, if you take good care of your coolant system, it will take good care of you.

A car’s engine creates a lot of heat – so much heat, that if it is not properly cooled, the engine can lock up, resulting in massive damage and repair bills. But when everything is working right, your engine operates at the proper temperature and all is well. Without antifreeze in your cooling system, the water could freeze and cause engine damage. This could be very expensive, not to mention inconvenient.

The right mix of water and antifreeze protects the engine against damage from freezing and overheating. Antifreeze also protects the coolant system against corrosion that could cause the system to fail. The thing to remember is this: coolant system failure is very common, but it is also very easy to prevent. Your Aurora service center knows the manufacturers’ recommendations, and can tell you when the coolant needs to be changed. They can also perform a coolant system service.

Give us a call or stop by for a coolant service or checkup.

Even the best antifreeze cannot completely protect the coolant system from harmful deposits forever. The anti-corrosion additives are used up over time, so the coolant must be replaced. A coolant service cleans out the system and replaces the old fluid with fresh coolant. A coolant system service is a low-cost way to protect against major engine repairs down the road. Prevention is the key. Be sure to watch out for the two main warning signs: if your temperature gauge is in the “hot” zone or if you get a message warning you to check your coolant. If you take a look under the hood, you will see the coolant overflow bottle. You can see there are lines that indicate the proper level of coolant … if your engine is cold – or if it is hot.

You can add water or antifreeze to that bottle yourself, but be careful. First, you never want to open the radiator pressure cap. The steam could severely burn you. Second, try to get to your service center immediately if your coolant is low. If that is not possible, follow the directions in your owner’s manual. Third, remember that you need a proper mixture of water and antifreeze, or you will damage your engine. If you make an emergency addition to your cooling system, follow-up with your service center where they can make necessary corrections. Fourth, not all cars use the same type of antifreeze.

You will need to check your owner’s manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. If you’re not sure, ask your service technician at Sterling Automotive Repair for guidance.

If you’re reading this article in Aurora Illinois, then you probably care about your car and how it runs. Even though you care, there is still that moment of dread when your service technician tells you the manufacturer recommends some additional service. Your heart beats a little faster, your blood pressure rises. You worry about spending more money than you expected.

And you worry that if you say “no”, you might be harming your car or compromising safety.

At the risk of sounding like your dad, you really should have done your homework. All of this stuff is in your owner’s manual. But it is not like you want to keep your maintenance schedule on your nightstand for bedtime reading.

Cars are complicated machines and it takes care to keep them running well. That is why manufacturers have maintenance schedules that explain how to keep your vehicle performing efficiently and prevent costly break downs. In a typical owners manual you’ll find: oil change, brake fluid and pad change, coolant system service, transmission service, battery electrolyte levels, cables and terminals, tire pressure and wear, CV boots, cabin air filter, air conditioning, heater, fuel filter, air filter, belts and hoses, power steering fluid, differential service, fuel system cleaning, and wheel alignment. And then there are mechanical service requirements like timing belt changes, valve adjustment, steering function, engine and exhaust leaks – yeah, it is a really long list!

Fortunately, this isn’t a test: You don’t need to have it memorized. Your service center at Sterling Automotive Repair has access to your manufacturer’s recommendations. So do not be surprised when your technician at Sterling Automotive Repair reminds you something is due. Your manufacturer has taken great care in putting together your maintenance schedule. Let Sterling Automotive Repair help you stay on top of important maintenance. You can expect them to suggest recommended services and tell you what problems they find under the hood. We’ll also explain how urgent these services are so you can work them into your budget.

Sometimes we hear people say, “What’s up with all this maintenance stuff? Modern cars just don’t break down.” While it is true that today’s cars and trucks are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most folks don’t realize how high tech automotive fluids have become. Fluids like, engine oil, transmission fluid, coolant and brake fluid.

Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today’s automotive fluids contain a much higher percentage of additives to protect your vehicle’s components from premature wear and corrosion. Time and miles march on for all of our cars. Please don’t think we’re using scare tactics to get you to take care of your maintenance – but here are some personal stories from AutoNetTV staff members to emphasize the importance of getting things done when they are due. Names are withheld to avoid embarrassment to those who should know better. Even though they should know better, it usually comes down to real life: time and budget. But they are tales of a stitch in time saves nine.

The first comes from a staffer who bought a used pick-up truck for his son. The oil was clean and all the fluids were topped off. A short time later, the truck overheated on the highway and shut down. The repair shop diagnosed the problem: the radiator pan was corroded and dumped the coolant. Even though the coolant level was correct, it was clear that the coolant had never been exchanged – just topped off from time to time. While this kept the engine cool, all of the anti-corrosion additives had worn out; the coolant became acidic and ate through the radiator pan. The cost: hundred of dollars and four days in the shop. This demonstrates the need to get your coolant exchanged on schedule.

Another story involves the true cost of skipping an annual inspection. Our staffer took his SUV in for the Illinois safety inspection to renew his registration. At the inspection station, he learned that the law had changed and that his newer rig only required an inspection every two years. He was very happy to save the $45 bucks. The problem was, his rear brake pads were very worn. Two months later, it was bad enough that he could hear the grind – over the radio, DVD player and the kids. He took it in to get the bad news. Both of the rear brake rotors were damaged. The left one could be resurfaced. The right had to be replaced. So saving a few bucks on his safety inspection turned into an extra $500 over what brake pad replacement would have been. Moral of the story: don’t skip your annual inspections. The irony is that many Aurora service centers would have done a brake inspection for free.

Next: a teenage daughter and a curb. Daddy’s little princess smacked a curb when she turned into a shopping center and popped the tire. The problem came when Dad didn’t get an alignment. The impact was hard enough to ruin the tire – so it was hard enough wreck the alignment. But instead of an alignment after the first tire, Papa ended up buying a second tire a few months later – and then an alignment.

Situation: son and wife with cars from the same manufacturer with essentially the same engine. Our staffer checked the son’s maintenance schedule and saw that it needed a timing belt replacement at 90,000 miles/145,000 km. He had it done – it cost several hundred dollars. His wife’s car had about 60,000 miles/97,000 km, so it should be ok for a while. Right? Wrong. The problem was that the wife had the turbo charged version. Its belt was scheduled for replacement at 60,000 mi/97,000 km. At 63,000 mi./101,000 km, the belt snapped on the interstate. The valves all crashed down into the cylinders at high speed and the entire head was shredded and had to be replaced. The cost: several thousand dollars. Does he wish he had checked the maintenance schedule? You bet he does – every time he passes a big-screen TV.

We’re talking about taking care of little things before they become big things. And when you take care of the little things, your car runs better and is more economical to operate. Remember to save those maintenance records. It’ll show potential buyers that you’ve taken care of your vehicle and it will help you get a better price. Or when you buy a used car, check those records. If there aren’t any, assume that the maintenance hasn’t been done and take it to your Naperville or Plainfield service center for an inspection. Take care of unperformed maintenance sooner rather than later.

Your vehicle manufacturer publishes two auto maintenance schedules. The regular schedule and the severe service schedule. It’d be wrong for us to tell you that everyone in Naperville always needs to follow the severe service schedule – but its wishful thinking to say that the regular schedule is always good enough for your sedan.

You can find us at:
9 S. Route 59
Aurora, Illinois 60504
Or call us at 630.851.3610

At Sterling Automotive Repair we’ll give you the definitions and explain the issues, and you can be the judge. Most manufactures list the following as severe conditions:

• Most of your trips are less than four miles.
• Most of your trips are less than 10 miles and outside temperatures are below freezing.
• The engine is at low speed most of the time – not on the highway.
• You operate your vehicle in dusty areas.
• You regularly tow a trailer or carry heavy loads.
• Driving in very hot or very cold weather.

So think about your typical week. Do you live a block from a Illinois freeway on-ramp and enjoy a non-stop commute to work in Naperville or Plainfield? Or are you like the rest of us where 90% of our trips are on the severe service list?

The answer may be different at different times of the year and for the different drivers in your family. Think of the two service schedules as bookends. Let’s suppose your owner’s manual says the severe service oil change recommendation is 3,000 miles and the standard recommendation is 5,000 miles. You know that you need to change the oil somewhere between 3,000 and 5,000 miles. Look at your driving patterns and Aurora road conditions and honestly evaluate which end of the spectrum you’re closer to.

If you have a job in a neighboring town such as Aurora or Naperville and most of your commute is freeway miles, you may choose the regular service schedule for your car. On the other hand, if you live within a few miles of work and only get on the highway a handful of times every month, something closer to the severe service schedule is more appropriate.

Now why is this so important? Moisture builds up in the engine oil from normal condensation. Short trips around Naperville or driving when it’s really cold means that the engine doesn’t heat up enough for the moisture to evaporate. The water in the oil leads to oil sludge that gums up your engine and doesn’t let the oil protect it as well. That’s why you need to change your oil more frequently – to get the sludge out before it causes problems.

Towing, heavy loads and very hot Illinois summer weather means that your engine and transmission will operate at higher temperatures and with more stress. The fluids will break down more quickly. Additives that clean and prevent corrosion will be depleted sooner. Dusty conditions, which may extend also to areas with high air pollution, mean that fluids will get dirty faster and that filters will plug up and won’t work right.

All of these things can lead to premature wear and repairs down the road. They’ll also hurt your fuel economy. If you want some personalized advice, talk with your cheerful Sterling Automotive Repair service advisor. We can help you restore your vehicle to good working order and help you know the best schedule to follow. If you’re not sure, err on the side of protection.

Bad air quality while you’re driving around Aurora is nothing to sneeze at. But seriously, more and more vehicles these days come equipped with a cabin air filter. Since they’re fairly new on the scene, a lot of folks don’t know about them yet.

These filters clean the air in the passenger compartment, or cabin, of your car or truck. They do the same job as the furnace filter you have at home. They can filter out particles as small as thee microns. By contrast, a grain of sand is about 200 microns.

So your cabin air filer can clean out dust, pollution, pollen and spores, to keep the air in your car nice and clean. And just like your furnace filter, they need to be replaced when they get dirty. Check your owner’s manual, but they typically need to be replaced at around twelve to fifteen thousand miles.

The filter is usually either under the hood or under the dashboard. Some are a little tricky to get to, so you’ll want to have your Aurora Illinois service center, Sterling Automotive Repair, take care of replacing them.

As we said, many people don’t realize they have a cabin air filter and go to their shop complaining about a funky smell in the ventilation system. It turned out to be a cabin air filter that was long overdue for replacement – really dirty and starting to smell. A quick replacement and they were on their way and smelling fine.

People who are allergy sensitive can really benefit from a cabin air filter, as it keeps allergens to a minimum. If you’re one of them, you’ll want to stay on top of your filter replacement schedule.

Of course if you do a lot of driving in dusty or polluted conditions, you’ll need to change your cabin air filter more often.

The popularity of biodiesel comes on the heels of many shifting priorities here at home and across the pond. Now that the cost of premium is comparable to a gallon of diesel, with prices expected to drop another 3% next year, it now makes sense for those on the market to consider diesel engines. Excise and income tax refunds create an additional incentive, as well as higher fuel emission standards agreed between auto manufacturers and the Obama Administration.

Canada is planned to open a biodiesel manufacturing plant Methes Energies to supply the US domestic market next year. The new plant, along with subsidies and changes in policy have all contributed to the US producing at a competitive costs on the european market. EU biodiesel giant ePure has challenged this, but the European Commission sidestepped the issue of tariffs and packed a one-two punch by capping first-generation biofuels at 5%, breaking an earlier promise to meet an already less-than-ambitious 10% in 2010. Biodiesel manufacture say this threatens 30% of their workforce, who are mostly farmers on contract, and 40% of their sales.

Meanwhile, manufacturers have been all but mute on the issue. Currently, BMW says only that they support B5, warning that the use of high pressure injection system will have trouble injecting biodiesel blends above 5%. BMW has already demonstrated their commitment to fuel economy especially with the M-series, but the new diesel engines may not exceed expectations.

Over on the Bimmerfest forum, users suggest that higher blends can contaminate engine oil requiring frequent oil changes, and can create rather than reduce emission problems. What comes next, if anything, is speculative. Forum users balk BMW’s transparency on the issue.

The volatile biodiesel market comes amid concerns over sustainability. The alternative fuels reliance on corn, sugarcane and soybean crops could aggravate a global food crisis, and more energy efficient methods of extracting energy from these algae-based bacteria are still in the early stages of research. One particular strategy is being developed in fish, where the algae consumed is stored in the fishes lipids whereby fatty acids can be extracted for production. This option is non-toxic as the process requires no chemicals and can be done in a one-step “single compartment process.” In a word, they can efficiently be packed like sardines. These fish also do not require freshwater because they are not intended for consumption. Environmental rights groups and food NGOs may find this solution, however, less than optimal.

European Car Magazine recently caught up with the driver and compared the experience of riding in the 4.9 HP/lb with ESS VT3-750 supercharger kit to a “blind folded-lap dance.” The journalist seemed outright scared of what might happen with a machine with stock suspension and overall seemed concerned about its handling, stop and safety. But Johnson obviously isn’t compared about street safety. These videos of him on private tracks in the southwest just go to show how insane he is.

 The 328i Sports Wagon is the third generation in a BMW pet-project with the performance you’d expect and all the features of a family wagon including extra storage, a sunroof and roof rails. The four-door wagon includes a 240hp producing N20 N.0 L 4-cylinder turbo engine that gets 30 MPG highway and can reach 60 mph in 6.2 seconds. This unique coupling of muscle and practicality offers a “versatile platform with engaging performance” according to European Car Magazine.

It should first appear on the market as an automatic and will be available in the Modern, Luxury, Sport and M Sport Lines. Following that, BMW North America will introduce an iDrive version to follow with a 6-speed manual transmission and recommended gear shift. Rear and front wheel drive will be made available.

In terms of the ride, some reviewers have noted a firmer experience due to stiff rear springs that were added in order to support the added weight capacity, while still acknowledging the exceptional steering feel and body control. This should come in handy on bumpy back roads. In short, it’s the best of both worlds for moms and dads seeking adventure in the outdoors with added fuel economy. The price tag on the 3-series Sports Wagon starts at $37,395.

Today at Sterling Automotive Repair we want to talk with you about a very important safety issue. This automotive safety warning is coming from a very unusual source: fire fighting experts. You’ve probably heard of E-85 gasoline being offered in the Naperville area. Some newer vehicle models are specifically built to run on E-85 – the rest are not.

Does your vehicle use E-85 gasoline? Bring it down to Sterling Automotive Repair at 9 S. Route 59 in Aurora, Illinois 60504 to find out, or give us a call to make an appointment by calling 630.851.3610.

E-85 gasoline has been developed to fight air pollution and reduce oil consumption. E-85 fuel is a mix of 85% ethanol, a grain-base alcohol, and 15% gasoline. So-called Flex-Fuel vehicles are designed to use either normal gasoline or E-85 gas. The result is lower harmful exhaust emissions to our local Naperville community.

All gas engines can run with up to 10% ethanol and in fact a lot of gasoline sold in the Aurora Illinois area does contain some ethanol. The problem comes when well meaning people without Flex Fuel certified vehicles put E-85 into the tank.

At a 15% concentration, the potential for problems arises. Because of the chemical differences between ethanol and gasoline, special seals and gaskets are needed for Flex Fuel vehicles in Aurora Illinois. In a normal engine, the ethanol in E-85 gas will eat away important seals and gaskets. This leads to gas and oil leaks.

You can imagine the fire hazard caused by leaking gasoline. Fire fighting experts caution consumers to only use E-85 if they know they vehicle is certified to handle it. They expect vehicle fires to increase because of using the wrong fuel in non-Flex Fuel vehicles.

So are people who don’t have a Flex Fuel vehicle but use E-85 to help the environment actually putting themselves at risk? Yes. In fact, service and repair centers in Aurora Illinois are being warned to purchase fire extinguishers that use the special foam needed to extinguish ethanol fires as a precaution in case starting-up an ethanol damaged engine leads to a fire.

Obviously, this isn’t something you want to have in your Aurora Illinois garage at home, either. If you have a Flex-Fuel certified vehicle, feel free to protect the environment by using E-85 gasoline. If not – please do not use E-85 in an engine that’s designed to run on unleaded gasoline only. At Sterling Automotive Repair we are concerned about your safety. If you have questions or want to find out how to determine if your vehicle can safely use E-85, go to www.e85fuel.com for more resources.

Tires do a lot of work. They transfer engine power and braking forces to the road; they handle steering control; and they cushion all those bumps and jolts. They also support the entire weight of the vehicle, including you and your passengers. With such critical work to do, you want your tires to do their job well. And since replacing tires is fairly expensive, you want them to last as long as possible.

There are three keys to long, even tire wear:

• Proper tire inflation
• Proper wheel alignment
• Regular tire rotation and balancing

The front tires on a car take the brunt of the steering forces. As they push through turns, the shoulders of the front tires wear down more quickly than the rear tires. Rotating front and rear tires allows them to all wear at about the same rate. That’s especially true of front wheel drive vehicles whose front tires steer, and put the power to the road.

SUVs and pick-ups, especially four wheel drives, also tend to wear their tires more unevenly than cars because of their suspension and drive train set-up. Your owner’s manual will likely contain a schedule for tire rotation. It’s usually every 5,000 miles or so.

Also, there are different rotation patterns for different vehicles. Sterling Automotive Repair will know which is right for your vehicle. That brings us to wheel balancing. When wheels are balanced, they spin on the axle evenly. When they are out of balance, they wobble a bit. That makes the tires wear unevenly and may transmit a vibration to the car. Your service technician at Sterling Automotive Repair puts weights on your wheels to balance them out so that they turn true and smooth.

Tires are a big investment for any vehicle. They’re critical for keeping you safely on the road. The cost for regular rotation and balancing is more than made up in extended tire life. And, can you really put a price on your safety and that of your passengers?

For those of you in Aurora Illinois who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.

For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same gas mileage. The turbocharged version makes over 350 horsepower.

So what are the differences from a conventional engine?

The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it’s then drawn into the engine with the air.

With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.

First, the fuel is squirted in at hundreds of times more pressure, so it’s atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.

Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can’t do its job as well. That means less power and worse fuel economy for your sedan and can lead to damaged fuel injectors.

Replacing fuel injectors isn’t cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we’re talking mortgage payment-range to replace a set of diesel injectors.

A professional fuel system cleaning from Sterling Automotive Repair gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they’ll last a long, long time.

Local Naperville roadside emergencies can range from a flat tire downtown to being stranded in a snowy ravine for three days. So you may want to consider a basic emergency kit to keep in the car at all times and a travel kit tailored to a specific trip.

Your close-to-home kit for around Aurora would have some basic items to work on your car: everything you need to change a tire, gloves, a couple quarts of oil, some antifreeze and water. A can of tire inflator is a great temporary fix for minor flats. You’ll also want jumper cables or a booster box, flares, a flashlight and some basic hand tools.

Now for your comfort and safety: a first aid kit, drinkable water, high calorie food (like energy bars), blankets, toilet paper, cell phone, towel, hat and boots. Keep some change for a pay phone, emergency cash and a credit card.

People who live in areas with frequent severe weather or earthquakes may want to carry provisions for longer emergencies.

For trips away from home, consider the weather and geography as you assemble your emergency supplies. You’ll need to have a source of light and heat and will want to provide protection against the elements as well as adequate food and water for everyone in the car.

Always tell people where you are going and have a plan for checking in at waypoints. Then if you run into trouble, you can be reported missing as soon as possible and rescuers will be able to narrow the search area.

The key to safe travel is to keep your vehicle properly maintained, plan ahead, and let others know your itinerary.

When I was a kid in Aurora, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it’s about time to get into Sterling Automotive Repair for my checkup and he said that he read on the internet that modern cars don’t need seasonal service.

My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense.

Back when my dad was teaching me about how to take care of the family sedan, most cars used a different weight of oil in the winter and in the summer. But most of today’s modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes.

Your owner’s manual or Aurora service advisor at Sterling Automotive Repair can tell you the right oil to use.

Of course, you’re concerned about the coolant or antifreeze. You don’t want to overheat in the Illinois summer or freeze up in the winter. Your engine cooling system protects against both of these things. And modern coolant, or as it’s sometimes called; ‘antifreeze’, is up to doing both very well. It’s designed to last for more miles than most people drive in a year or two.

So how does a Spring and Fall check-up fit in? Let’s start with Spring. Summer is coming. That means heat, more miles driven and road trips. It just makes sense to check your fluid levels and do a visual inspection to see that everything is up to snuff.

You may not be scheduled to drain and replace the coolant for some time, but you need to make sure you have enough coolant, and that you don’t have any leaks or hoses that are about to fail.

That’s pretty practical; a check-up to see if there are any problems or emerging conditions that could later become a problem, like a cracked belt.

And the same principle applies for getting ready for winter. Cold weather means lots of failed batteries. It takes more power to crank up a cold engine, and cold also decreases the available cranking power the battery has available.

So a battery test in the Fall could tell you if you’ve got a battery that is running on its last legs. And of course, if you live where winter temperatures get below 45 degrees or you have ice and snow, you’ll want to consider changing to winter tires.

So Spring and Fall auto checkups at Sterling Automotive Repair are practical reminders to get ready for the demands of the hot and cold seasons to come.

And odds are that you have one or more routine services that are due anyway. Like a transmission service, brake or power steering fluid, differential service – stuff like that. Are your wiper blades still good? Are your headlamps starting to dim?

So Spring and Fall: change your clocks, replace the batteries in your smoke detectors – and get a check-up for your cars.

See, dad was right again.

Come and see us at Sterling Automotive Repair for your Spring and Fall automotive checkup.

If you’re a quart low in your sedan, there isn’t enough motor oil to lubricate your engine properly. The extra friction causes drag that reduces fuel economy while you’re driving around the Naperville area.

The same goes for dirty oil; it doesn’t reduce friction properly. The result is you get to watch those numbers at your local Naperville gas pump rolling higher and higher.

The transmission also needs the proper amount of clean fluid to do its work. When it’s in need of service, the transmission drags your fuel economy down.

So keep it clean and give yourself a fighting chance.

You would never like to drink a glass of mud, right? Well, your car feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter’s job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won’t start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your car will still run. But, then the contaminated fuel can plug your fuel injectors and allow damaging particles into your engine.

A car with a partially clogged fuel filter might run well around town, but sputter and strain on the highway because it’s starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive and the gas you buy. If you drive a lot on dirt or gravel roads in rural Illinois, your fuel filter will have a harder time keeping the fuel clean.

And, we hate to say it, but buying the cheapest gas from cut-rate Naperville area stations sometimes means dirtier fuel that’ll clog the filter sooner. Major brands tend to be cleaner and certainly have higher levels of detergent additives.

Of course, your manufacturer recommends intervals for changing the fuel filter. But, it’s a little more complicated than that. Some manufacturers stopped listing recommended intervals for fuel filter replacement or have very long intervals like every five years or eighty thousand miles. So you may need to look to other sources for recommendations. Cars older than six or seven years are especially at risk because they have had time for dirt and rust to build up in the fuel tank. A clean fuel filter keeps the gas flowing. Even a partially clogged filter puts added strain on the fuel pump. That can shorten its life and result in a costly repair.

As is often the case, spending a little money now on something as inexpensive as a fuel filter can save money down the road. At Sterling Automotive Repair in Aurora, we can check your fuel filter. It is better than fixing a burned out fuel pump or ruined fuel injectors.

Your car might have an alignment problem if: it drifts or pulls to one side, your steering wheel is off center, you have uneven tire wear or your car doesn’t feel like it handles right. When all of a vehicle’s wheels are lined up exactly with each other, your wheels are in alignment. Running into potholes, smacking a curb or other object are great ways to knock your car out of alignment. Then one or more of your wheels starts pulling in a slightly different direction and the problems begin.

Driving for an extended time when you’re out of alignment causes your tires to wear unevenly and excessively. This can be dangerous and expensive. You’ll have to replace your tires sooner, but even worse – you may cause premature wear to your suspension system, which can be really expensive.

The front wheel alignment is adjustable on all vehicles, and the back wheels are also adjustable on some cars. The adjustment can go three different ways. The first adjustment is called toe. The next adjustment is called camber. And finally, there is castor. The engineers who designed your vehicle determined the alignment settings that will give you the best handling and safety.

There are several things involved in an alignment check. First, there’s an inspection of the steering and suspension – it should be checked to see if anything’s bent or broken. Then the tire condition needs to be inspected. From there, the vehicle is put on an alignment rack and an initial alignment reading is taken. If all four wheels are adjustable, they are lined up perfectly parallel with the vehicle’s center line. If the back wheels aren’t adjustable, a technician at Sterling Automotive Repair can determine the direction they push and then aligns the front wheels to match.

Like most things, your manufacturer has suggested a mileage interval for having your alignment checked. But if you run into a curb, pothole or something else that’s given you a big jolt, pay attention to whether your vehicle is pulling to one side when you drive. It’s better to have your alignment checked before waiting to see if there is uneven tire tread wear – by then, the damage is done.

Getting your alignment checked when needed is a great way to extend the life of your tires and suspension parts. It also makes sure that your tire meets the road properly for maximum performance and safety.
