Let's take engine oil. Twenty or 30 years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.

It was common in those days to use a lighter weight oil in the winter when it's cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn't thin out too much in the summer heat and vaporize in the engine.

Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the vehicle has been turned off for a while, the oil tends to run down to lower areas.  That means the valve train parts are vulnerable at start-up, before the oil starts circulating.

So new weights of oil have been introduced to meet the engineering specifications of these newer engines.

Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. It's certainly in the owner's manual. Of course, TJ's Auto Center Inc. in Rockford can look it up for you.

It's more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.

Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.

In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.

So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasn't formulated to protect your plastic cooling system parts, they could become corroded and fail. And if you're using the wrong coolant, your cooling system won't be covered under warranty. So it's important to use the right coolant and to not mix different types.

Your owner's manual or service advisor at TJ's Auto Center Inc. can make sure you're using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. That's OK for an emergency top off, but following your manufacturer's recommendation for your vehicle or other auto type is always a safe bet.

In the area of brake fluid, there are a couple of new formulations. It's important to remember that the new ones aren't better than the old ones. They're just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.

There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid and so on that contain additives to condition and restore seals and gaskets in older engines.

They're fine to use as long as they're a variant of the proper fluid. In other words you can use a high mileage engine oil as long as it's also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as it's the right type for your transmission.

Diesel Maintenance for Illinois

At TJ's Auto Center Inc. we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV's. But our Illinois friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there're nearly as many diesel powered passenger cars as there are gasoline.

Here's who's announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in Illinois.

You may ask, why has it taken so long getting to Illinois and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that Illinois diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up Illinois to the engines the rest of the world's been enjoying for a long time.

Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there's none of that black smoke we used to see.

Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.

Repair costs are similar to vehicles with gas engines. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system and so on. And the payoff for you, if you're the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for many, many years.

Charge It in Rockford for Extended Battery Life

Here's an interesting statistic for our in Rockford, Illinois, drivers: Only 30 percent of car batteries make it to 48 months. And the life expectancy varies by where you live. It ranges from 51 months in extremely cold areas to just 30 months in extremely hot climates.

Why is that? It turns out that it's our modern cars with all their electric accessories that are to blame. Things like, GPS, DVDs and entertainment computers are keeping vehicle batteries from maintaining a full charge. The longer a battery goes with a low charge, the sooner it'll die.

It's clear that you Rockford drivers need to recharge your batteries. This is the job of the alternator. The problem comes when the car's demand for electricity is high and we are driving in stop and go conditions or short trips around Rockford. The alternator just can't keep up.

The result is shortened battery life. So what can we do to improve our battery's health?

We need to keep the battery as close to a full charge as possible. That can be hard because sitting for just 24 hours in hot weather between charges can be too long. When the weather's cold in Rockford, sitting for several days will cause discharge.

So some highway driving around Illinois will help keep a full charge if the battery has not been deeply depleted. Car batteries are not designed to be run down really low, or deep cycled, as it's called. So using your headlights or other power accessories when the car is off can deeply deplete your battery. Using the alternator to recharge from a deeply depleted state is also very dangerous to your battery because it charges too fast. In fact, on average, your battery would only last for ten recharges like that.

If you do find yourself with a dead battery or very low battery, use a good quality battery charger to slowly bring the battery up to full charge. Follow the instructions on the charger or talk to your friendly and knowledgeable service advisor at TJ's Auto Center Inc. .

Defensive Driving in Rockford, Illinois

There was a man in the Rockford area who learned that most car accidents occur within a mile of home – so he moved. (Just kidding!)

When we think of defensive driving, we often focus on our local Illinois highway situations. The fact of the matter is we need to be just as careful close to home in Rockford, because that's where we do most of our driving. We can't let our familiar surroundings keep us from driving defensively.

Defensive driving begins with the proper attitude. Have in mind that you won't let anyone take your safety away from you. You'll be aware of your surroundings, road conditions, other vehicles and hazards. And the first person to be concerned with is you: start with your own environment.

Don't leave without securing all occupants including children and pets. Watch for loose items that can become projectiles during evasive maneuvers.

Driving too fast or too slow increases the chance of an accident.

Never drive impaired: Alcohol is a factor in half of all fatal crashes. Never drink and drive.

Other impairments include being sleepy, angry, daydreaming or talking. If you suddenly wonder how you got where you are – you're not paying enough attention.

Keep your windows clean and uncluttered. No fuzzy dice and stickers.

Keep your car in good shape so that it handles properly: Maintain tires, lights, brakes, suspension, wheel alignment and steering.

Always use your turn signals while driving around Rockford, Illinois. Avoid other vehicles' blind spots.

Don't drive faster than your headlights – if you can't stop within the distance you can see, you're going too fast.

Avoid driving over debris in the road. Even harmless looking items can cause damage or an accident.

Keep your wheels straight when waiting to turn at an intersection in Rockford . That way if you're hit from behind, your car won't be pushed into on-coming traffic.

My daddy always said that when you drive, you're actually driving five cars: yours, the one in front, the one behind and the ones on either side. You can't trust that other drivers will do the right thing, so you've got to be aware of what they're doing at all times.

If you see another car driving erratically, weaving, crossing lanes, etc., stay back. Take the next right turn if you're downtown Rockford, or take the next exit on the Illinois highway. Notify the police if you see someone driving dangerously in our Rockford community.

Never follow too close. The minimum distance is the two second rule. Pick a landmark ahead, like a tree or road marker. When the car in front of you passes it, start counting: 'one-one-thousand, two-one-thousand.' If you pass the landmark before reaching two-one-thousand, you're following too close.

Remember that the two second rule is the minimum – it assumes you're alert and aware. Three seconds is safer. Move out to five seconds or more if it's foggy or rainy.

Someone will inevitably move into your forward safety zone – just drop back and keep a safe distance.

If someone follows you too closely, just move over.

Don't play chicken by contesting your right of way or race to beat someone to a merge. Whoever loses that contest has the potential to lose big and you don't want any part of that. So stay alert, constantly scan around your car and arrive safely.

Economics of Maintenance for Rockford Auto Owners

Buying a new car in Rockford is always a big financial decision. The allure of that new car smell is powerful, to be sure. But what if your current car is still in good shape? How do you decide?

People in Rockford who've been used to driving a new car every three to five years may be having second thoughts in this economy. For many, the question is, how does the certainty of a new car payment stack up against uncertain repairs for a car that may be out of warranty?

For purposes of our discussion, let's assume you live right here in Rockford and have a five year old vehicle. It's now paid off. If you keep it, you fear that there'll be some repairs over the next five years, but you really don't know what to expect. For help we turned to maintenance and repair information for cars and trucks. With this data, they project likely service and repair costs for a particular make and model. They're able to use manufacturer's maintenance schedules and repair histories for the projections.

Of course, these projections can't predict what will happen to your vehicle in Rockford, but they do give you information to use in your decision.

Let's look at the numbers for a five year old Toyota Camry V-6. In this example, the combined maintenance and repairs for the five year period is $5,748. This works out to an average of $96 a month. The year-by-year averages range from a low of $49 a month to $124 a month.

So compare $96 a month with a new car payment. And it's actually better news than that; you would still have maintenance expenses with a new car, so the repair element could be less than half that figure.

Here are numbers for some other five year old vehicles from around Rockford:

• Ford Escape - $116 a month
• Chevy Silverado - $131 a month
• Jeep Grand Cherokee - $138 a month
• Hyundai Accent - $85 a month.

Now, if your vehicle is older than five years, have a chat with your Rockford service advisor at TJ's Auto Center Inc.. We see hundreds of vehicles through our bays every month and we know your car. See if there's any particular problem in common with your vehicle that you might see over the next couple of years.

And of course, the best way to keep future repair costs down is to take care of all your scheduled maintenance. This is especially important in older vehicles that have had time to accumulate some deposits.

There are special motor oil formulations that help clean older engines and protect and recondition their seals and gaskets.

We hope this eliminates some of the unknowns in the decision to keep or trade.

Give us a call if you have any questions.
