Weight is the enemy of fuel economy. Everyone from here to Byron Center knows this makes sense.

Some of us in the Byron Center area carry a bunch of unnecessary weight, and I’m not talkin’ what you see in the mirror.

Guys; sports equipment and tools. Ladies; well, just take a look around the passenger compartment and trunk. I think my car has about forty-five pounds of French fries on the floor.

All that extra weight wastes gas as you drive between here and Byron Center, and everywhere else.

Lose the junk and save some money.

…And you really only need one of those spare tires.

Everyone in Grand Rapids Michigan eventually replaces their tires, whether it’s because they’re worn out or they’re just looking for something different. There are so many great tire choices in Grand Rapids Michigan, it can be difficult to sort them out. Let’s group the broad spectrum into several categories that will help in the selection process.

One category is often referred to as “summer tires”. Summer tires are designed to be driven on the road when temperatures are generally above 45 degrees. Their tread design is optimized for traction on dry roads in Grand Rapids Michigan and they’re also able to effectively displace water on rainy roads.

Now the rubber compound gets a little hard and stiff as temperatures drop below 45 degrees as it occasionally does here in Grand Rapids Michigan. And the tread which handles dry roads so well, can get packed with snow or mud – which provides very little traction in those conditions.

So if you live where its summer all year round, these tires will work well for you. If you like maximum performance in warm weather, but still live where it gets cold and snowy, you’ll want to change your summer tires for winter tires as the weather starts to change.

Summer tires can be purchased with an emphasis on handling performance, smooth ride or long life. Your Grand Rapids Michigan tire professional at Ervine’s Auto Repair can help you find the right tire for the way you drive.

As you can imagine, winter tires are designed to work very well in snow and ice. Their tread is designed with many channels and grooves that throw the snow out of the tread as the wheel turns. This means the tire is always be able to bite into the snow.

The rubber compound used in winter tires is specially formulated to be flexible at temperatures below 45 degrees. This maximizes cold weather traction. When it gets warmer, the softer rubber will wear faster on warm dry pavement than summer tires, so change them out once the weather has turned.

There’s a range of tires within the winter tire category. If you live where there’s a lot of snow and ice, look for the mountain and snowflake icon that signifies a severe snow rating. If you have milder winters and still want a performance component, they make a winter tire for you as well.

For many people, an all-season tire is the answer. You will give up some of the performance at the extreme ends of the summer tire/ winter tire spectrum, but you will find a long wearing tire that gives both good highway performance and winter traction on our Grand Rapids Michigan roads.

Within the all-season category, there are many choices that you tire advisor can help you evaluate.

Outside of these three main categories, some people in Grand Rapids with trucks and SUVs like a tire that is designed for both on-highway and off-highway use. They can handle the rocks and bumps off-road, but still work well on the street. Again, many options depending on the relative emphasis on on-road verses off-road.

You may want new wheels to go with your new tires – well, there are hundreds and hundreds of styles to choose from. That’s a matter of personal taste. If you want to change the size of your wheels and tires, do get some professional help.

The computers on your vehicle are programmed to the size of wheel and tire combination that comes from the factory. Tire size affects various computer controlled functions like anti-lock brakes, traction and stability controls, speedometer and odometer. Of course, you want these systems to work properly. The computers can be re-programmed for different tire sizes.

And if you want to increase the size of your wheels and tires, you’ll want so help to make sure they’ll fit in the wheel wells of your vehicle without rubbing during turns or over bumps.

Every Grand Rapids car owner who has taken their car in for an oil change has been told that their engine air filter’s dirty.

Here’s what goes into the determination of when to change the filter: First, your sedan owner’s manual will have a recommendation of when to change the filter. Second, a visual inspection by your Grand Rapids technician may determine that your filter it is visibly dirty and needs to be changed.

So between your owner’s manual and your Grand Rapids technician’s inspection there’s really no guesswork involved.

Now, most air filters purchased in Wyoming, Kentwood, or Byron Center don’t cost a lot to replace. It’s just that Michigan people hate getting caught with an unexpected expense. On the plus side, though, changing a dirty air filter at Ervine’s Auto Repair can often save enough on gas to pay for itself before your next oil change in Grand Rapids.

Think about a dirty furnace filter in your Kentwood home. When it’s all clogged up, enough clean air can’t get through. In your sedan, that means that your engine can’t get as much air as it needs to burn the fuel efficiently. So it makes do with less air and has to use more expensive Michigan gas to move your vehicle around Grand Rapids roads.

Your sedan actually needs about 12,000 gallons of air for every gallon of gas it burns. Engine air filters don’t cost much in Grand Rapids at Ervine’s Auto Repair. When it’s time to change yours, just get it done. You’ll buy less fuel, have better performance and protect your engine.

Suspension systems will continue to operate effectively for many years and tens of thousands of miles. Eventually sedan components do wear out, but how long that takes depends a lot on how you drive in Kentwood.

As you can imagine, if most of your driving is on smooth Michigan highways, your shock absorbers will last a lot longer than if you do most of your driving on bumpy roads or hauling heavy loads. In addition to just wearing out, sedan suspension components can be damaged in an accident or by a hard impact – like a pothole, hitting a curb or a rock in the road. Because the life span of shocks can vary so widely, your sedan manufacturer recommends periodic inspections.

During an inspection at Ervine’s Auto Repair, your honest and efficient Kentwood service technician will check for worn, broken or missing parts. Let me give a rundown of the major suspension components.

First there are the springs. The springs hold the weight of the vehicle. There are several kinds of springs. Springs are obviously heavy duty parts that rarely break or wear out. Shock absorbers work in conjunction with springs to smooth out the ride and help keep the tires on the road. The shocks are key to handling performance and ride comfort.

You’ve probably heard of struts. They combine a shock absorber and a coil spring in one unit. Shocks and struts will wear out over time. There are some signs that shocks or struts are wearing out. The tires may have a cupped wear pattern. This is from the shocks bouncing unevenly. You may notice a floaty or drifting sensation when cornering. If the front of your sedan dives excessively when stopping, or rocks back and forth after you stopped, your shocks may be worn out. And if they are leaking fluid, it’s definitely time to replace them.

If you are experiencing any of these symptoms, visit Ervine’s Auto Repair for a suspension inspection. Same if you’ve been in an accident that involved one of your wheels. If your sedan suspension actually fails, it could lead to a serious accident, so take care of these things.

When you replace your shocks, it’s usually a good idea to replace all four at the same time. That’ll give you more even handling. Talk with your Ervine’s Auto Repair service advisor because you don’t want a big difference between the performance of your shocks from wheel to wheel, and replacing all may be the safest bet.

There different grades of shocks and struts. You always want to use a replacement shock or strut that equals the one that came as original equipment when your sedan was new. But remember, they were designed to meet the expected needs of the broad range of Kentwood people who buy that particular vehicle. Your needs may be more specialized.

For example if you want increased handling performance for your sedan, your honest and efficient Ervine’s Auto Repair advisor can recommend an upgraded shock or strut to give you what you want. If you haul heavy loads or trailers, you can get a more heavy duty shock absorber.

Here’s a travel tip that’ll I’ll bet you didn’t know, and, it might keep you safer…

The average American commuter in Michigan spends two and a half hours daily in their car.

The government says a hundred thousand auto accidents yearly are caused by drivers who fall asleep at the wheel. (Aggressive driving is the number one traffic safety concern.)

So what does this have to do with how your car smells while you’re driving around Michigan?

Well, which scent did you think makes drivers more alert?

Is it:

• A. Strawberry
• B. New Car
• C. Pine
• D. Warm Vanilla Breeze

It’s C. Drivers are more alert and have less fatigue with pine scent in the car, according to AroMetrics.

And, drivers were less angry with overall improved driving performance with strawberry and pine scents.

And you thought they just smelled nice.

In very simple terms, a fuel injector is a valve that squirts fuel into your sedan engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected car driving down Wyoming, Kentwood, and Byron Center roads.

Most fuel injectors for gas engines are known in the Grand Rapids auto industry as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

A few auto makers have recently introduced gas direct injection systems on some engines. They are now available at some Grand Rapids dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

Although more complicated, direct injection technology promises greater power with improved fuel economy for gas-poor Wyoming, Kentwood, and Byron Center commuters. Michigan motorists can expect to see more of it in the future.

High temperatures under your sedan hood and variations in Grand Rapids gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

When injectors are dirty, the fuel doesn’t burn as efficiently resulting in poor fuel economy and loss of power. So it’s important for Grand Rapids drivers keep their fuel injectors clean.

Your Grand Rapids Ervine’s Auto Repair service center can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Proper maintenance of your sedan fuel system means that you will spend less on gas, enjoy strong performance and prevent costly Grand Rapids repair bills down the road.

So, when are your tires actually worn out? This is a question a lot of us in Grand Rapids Michigan ask ourselves. For many, the answer is ‘when they no longer pass a safety inspection’. But waiting that long can have a serious impact on your safety.

The U.S. Federal government doesn’t have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider two-thirty-seconds of an inch to be the minimum legal tread depth. Two other states, including California, consider one-thirty-second to be the minimum and six states have no standards at all. Call us at Ervine’s Auto Repair (just call (616) 532-6600) to find out what your requirements are in the Grand Rapids Michigan area.

Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there’s just 2/32” of tread left. But does that older standard give you enough safety?

Well, Consumer Reports issued a call to consider replacing tires when tread reaches 4/32”. And the recommendation is backed by some very compelling studies. Now before we go into the studies, you need to know that the big issue is braking on wet surfaces.

We tend to think of the brakes doing all the stopping, but you also need to have effective tires to actually stop the car. When it’s wet or snowy in Grand Rapids Michigan, the tread of the tire is critical to stopping power.

Picture this: you’re driving over a water-covered stretch of road. Your tires actually need to be in contact with the road in order to stop. That means the tire has to channel the water away so the tire is actually contacting the road and not floating on a thin film of water – a condition known as hydroplaning. When there’s not enough tread depth on a tire, it can’t move the water out of the way and you start to hydroplane.

This is where the studies come in. We think you’ll be surprised. A section of a test track was flooded with a thin layer of water. If you laid a dime flat on the track, the water would be deep enough to surround the coin, but not enough to cover it.

A car and a full-sized pick-up truck were brought up to 70 mph and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths. First, they tested new tires. Then tires worn to legal limits. And finally, tires with 4/32” of tread were tested – this is the depth suggested by Consumer Reports

When the car with the legally worn tires had braked for the distance required to stop the car with new tires, it was still going 55 mph. The stopping distance was nearly doubled. That means if you barely have room to stop with new tires, then you would hit the car in front of you at 55 mph with the worn tires.

Now with the partially worn tires – at the depth recommended by Consumer Reports – the car was still going at 45 mph at the point where new tires brought the car to a halt. That’s a big improvement – you can see why Consumer Reports and others are calling for a new standard.

Now without going into all the details, let us tell you that stopping the truck with worn tires needed almost 1/10 of a mile of clear road ahead to come to a safe stop. Obviously this is really a big safety issue.

The tests were conducted with the same vehicles, but with different sets of tires. The brakes were the same, so the only variable, was the tires.

So, how do you know when your tires are at 4/32”? Well, it’s pretty easy. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Now you may remember doing that with pennies. But a penny gives you 2/32” of an inch to Abraham Lincoln’s head. The quarter is the new standard – 4/32”.

Tires are a big ticket item and most people in Grand Rapids Michigan want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out? For us, and we would guess for many, the answer is “no”.

Well, Mr. Washington, let’s go out and look at my tires.

In our auto video today we’ll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that “modern cars are so reliable, they are virtually maintenance free”.

Any good myth has some elements of truth. No offense to Grand Rapids Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn’t so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.

Here are some examples for our friends in Grand Rapids.

• Some cars in Grand Rapids no longer require chassis lubrication. They’re made with self-lubricating materials and have sealed joints. There’s literally is no way to grease those joints.

-Chalk one up for the myth.

On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts up in the valve train that didn’t even exist not that many years ago. These parts are very vulnerable to oil sludge.

• So, skipping an oil change here and there could lead to very expensive damage.

-A point to maintenance.

• Electronic ignition has eliminated replacing points.

-Myth gets a point.

• Fuel injectors on direct injection engines are very expensive to replace so one must be sure to get a fuel system cleaning on schedule.

-Point for maintenance.

I think you get the picture. As automotive technology advances, it eliminates or reduces some maintenance requirements. And maintenance becomes more critical for some items. Most others remain very similar to what they’ve always been.

So the maintenance mindset is still important for car owners in Grand Rapids if we want our vehicles to last a long time. The checklist may change over time, but there’ll always be a check list.

Let me mention a couple of items on modern vehicles that folks need to be aware of. One of the most of the most important is timing belt replacement. Used to be that all engines had timing chains – you know, metal chains. They rarely broke.

It’s cheaper to make engines with timing belts rather than chains, so replacing the timing belt is on most engines’ maintenance list. The money the manufacturer saves by using a belt is more than off-set by what the vehicle owner has to pay to replace the belt. And it’s a drop in the bucket compared to the cost of repairing the damage if the timing belt breaks.

So make sure you know when your timing belt needs to be replaced. You don’t want to miss that. If you have 60,000 miles or more, break out your owner’s manual or ask your Grand Rapids service advisor at Ervine’s Auto Repair to check on the recommendation right away.

Another is sealed wheel bearing assemblies on some vehicles. As you might have guessed, it’s cheaper to make a sealed unit than one that has access to inspect or service the wheel bearings. The problem is that when the bearings fail, you have to replace the entire unit, not just the bearings. That’ll cost 5 or 6 times as much.

For our friends in Grand Rapids, we hope this has underscored the importance of knowing and following your maintenance schedule. Come in and see us at Ervine’s Auto Repair. You’ll find us at 4311 Stafford SW in Grand Rapids, Michigan 49548. Just give us a call at (616) 532-6600.

If you’re reading this article in Grand Rapids Michigan, 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 Ervine’s Auto Repair has access to your manufacturer’s recommendations. So do not be surprised when your technician at Ervine’s Auto Repair reminds you something is due. Your manufacturer has taken great care in putting together your maintenance schedule. Let Ervine’s Auto 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.

We’re living in a disposable society. Everything from elaborate packaging to our clothing. Even cell phones are disposable. When replacement is cheaper than repair, the term “built to last” goes by the wayside. An exception is our vehicles. They’re still a very big investment and we want to make them last as long as possible – and we want to make keeping them as cheap as possible. When talking cars, it’s all about preventive maintenance. There is an old saying that says, “a stitch in time saves nine” and that is really true when it comes to taking care of your car. A great example is coolant service.

Your coolant not only protects your engine from overheating and freezing – it must also protect cooling system components from corrosion. Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. That’s why you need to have your cooling system serviced on a regular schedule.

The same is true for your power steering system, brake fluid, air conditioning system, differential and transmission. And of course, don’t forget those oil changes right on schedule. Skipping even one change can start the build up of harmful oil sludge.

Our engines are full of gaskets and seals. Fresh fluids condition those gaskets and seals to keep them from drying out and leaking. Automotive fluids contain additives that help clean and lubricate the various systems they protect. Over time, the additives are used up and the fluid just does not provide the protection it did when it was fresh. And don’t forget the mechanical systems. Changing brake pads before they are worn to the point that they cause damage to rotors is a great way to keep your operating costs down.

Replacing serpentine belts and timing belts on schedule is much cheaper than repairing the damage that can be caused by failure. Also, air filters, fuel filters, PCV valves and batteries are all important. Regular wheel alignments, tire rotation and balancing will make your tires last longer. And don’t forget to replace your shocks and struts when they wear out. Your fuel system needs regular cleaning to keep running well, prevent mechanical damage and reduce fuel consumption.

Now this is a lot to remember – too much really. But it is your Grand Rapids automotive technician’s job to keep on top of this stuff. At Ervine’s Auto Repair we can tell you what your manufacturer recommends and help you with a plan to take care of it. We can advise you about which maintenance schedule you should use – the regular schedule or the severe service schedule – depending on the kind of driving you do. We also know the right fluids for your vehicle and may even suggest higher mileage formulations for your older vehicle.

Bottom line – take care of this stuff on schedule and you will reduce operating costs, prevent costly damage and maintain your warranty coverage.

Of course, you want your car to look as good as it runs. Regular washing will prevent rust and protect your finish. Take advantage of cleaners, waxes and protectants for your interior and tires. Your vehicle will look great and you’ll be proud to drive it longer.

Most of us can’t afford to throw away our car when it breaks down. By budgeting for regular preventive maintenance, we can prevent many inconvenient – and expensive – problems down the road, and can keep driving “old faithful” for years to come.
