For 4x4s (Maintenance of 4x4 Vehicles)

Some people love 4x4 vehicles, the true 4-wheel drive works of engineering like Jeeps and 4x4 pickups that allow you to seemingly go anywhere on the planet. You can climb up a 40-degree rock trail with some planning and skill (always careful to protect the environment, of course), or you can get through the deepest snow.

But with that added capability comes additional complexity, drive-train components and other systems that less capable vehicles don't have.  And that is why when it comes to 4x4s, you have to maintain them a little differently from those vehicles that spend their lives on pavement.  Here are some of the key things to keep an eye on:

• Transfer case—This transfers power from the engine to the wheels.  A transfer case has fluid in it that needs to be changed at intervals recommended by the manufacturer.  Your service advisor will let you know how often that is and will keep track of your service dates.  You will need to make sure the transfer case seal is working properly.  Otherwise, transmission fluid could get in and cause damage that is costly to fix.  Some transfer cases have an electric motor that shifts it through gears, and its connections are often exposed to the elements, making them vulnerable to damage and corrosion.  Proper maintenance will keep those connections working like they should
• Front and rear differentials—These also have to have the right amount of fluid and should be checked regularly.  Your service advisor can let you know when you need that fluid changed as the owner's manual recommends.  It's important the service is performed correctly with the proper lubricant so it will work the way it is designed to.
• Brake lines—Those 4x4s practically beg to go into wet spots. They also are great machines to conquer snow: road salt, brine and all.  Moisture, salt and brake lines are a recipe for corrosion, so brake lines need to be inspected regularly.  There are anti-corrosion sprays or white lithium grease that can retard corrosion.  Remember, getting there is half the fun, but not being able to stop is no fun at all.

So enjoy your 4x4 and what it can do that other vehicles can't.  Just remember that even though it's tough on the outside, it needs special care to keep it going.  Oh, and remember to take care of the environment when you go off-roading, too. 

Steer Me Right! (Failing Power Steering Hose)

Most drivers love how easy it is to turn their vehicles, and they have power steering to thank.  Engineers have figured out a way to take some of your engine's power to help you turn. Without it, steering can be quite a chore.  New power systems are electric, but there are still plenty of the older hydraulic power steering systems out there, and it's wise to keep them working the way they should so you don't find yourself stranded without power steering.

Those hydraulic power systems use a fluid under pressure that is pumped to a device that helps you turn your wheels more easily.  It's that pressure that presents the challenge.  After your vehicle's seen a few years on the road, you may find your steering isn't quite as easy as it was.  You may hear a groaning or humming sound when you turn. 

One component that can fail is the pressure hose that carries that fluid from the power steering pump to that turning assist mechanism.  The hose is made of rubber and can leak, crack, get damaged by heat and debris or just get too old.  If yours is ten years old or older, it's likely getting close to the end of its life.

If you think you can just wait until it fails completely, think of these possible consequences.  If the hose or a coupling fails, power steering fluid can blow all over the hot engine.  That fluid is flammable and can start a fire.  Or if you've been driving for a few weeks with low power steering fluid, that could ruin your power steering pump. Replacing the pump is an extra expense you can probably  live without.

A technician will replace the necessary parts and make sure air and contaminants are bled or flushed from the system.  Then, he or she will check for leaks.  Just think how important a properly working power steering system is for safe operation of your vehicle.  Make sure you keep yours in top shape for your safety's sake and the safety of others on the road around you.

Getting from E to F (Fuel Gauge Problems)

Who thinks about their fuel gauge?  You probably don't… until it doesn't work any more.  Then you have to guess how much fuel is in your tank, and that's no way to live life on the road. 

Fuel gauges, like every other part in your vehicle, can fail.  And when yours stops working, you will probably want to head over to your service facility soon, because no one relishes running out of fuel.

The fuel gauge system is much more than just the gauge you can see on your instrument panel. Most systems have a float inside the fuel tank that goes up and down depending on the fuel level.  It's called the fuel sending unit, and it sends an electrical signal to the gauge (on the dash) telling it to display how much fuel is left in the tank. 

So, what could go wrong?  Well, a few things.  For one thing, corrosion from bad fuel can cause it to stick and it won't move up and down any more.  So you could fill up your tank and the gauge would still read Empty.  If a sending unit needs to be replaced, often the parts can be costly. The good news is that fuel sending units rarely fail and most drivers will never have one go bad.

Other things that can go wrong? An electrical problem could cause a fuse to blow and you won't get a reading at all.  A technician can figure out where that electrical problem is and how to repair it.  Finally, it's possible for the gauge itself (on the instrument panel) to fail.

One thing to keep in mind is if your fuel gauge isn't working, you might be tempted to carry around an extra container of fuel.  That's ok if it's outside the cabin, such as in the bed of a pickup.  But if you carry it inside the cabin or trunk, fuel fumes can be very dangerous for your health, even fatal.

A working fuel gauge gives you peace of mind… so you'll never have that "empty" feeling.

The McPherson Automotive Guide to Saving Fuel: Beware of Myths

There's a lot of auto advice in IL right now on how to save money on gas. Some of it is good advice. Some of it isn't. Some of it is myth. And it may well be a scam. Plain and simple. When someone offers you a product designed to save money on gas, ask yourself, “Does this sound too good to be true?” If the answer is yes, do more research.

The internet offers us a convenient and quick way to research someone's claims about gas savings. Du Quoin drivers can usually find out in only minutes whether that claim is questionable or not.

Chances are other Du Quoin drivers have already tried what you're being offered. If you find evidence that others feel they have been scammed, you should be wary of becoming the next victim. There aren't any pills, magic or otherwise, that you can drop into your gas tank to improve your gas mileage. Drop in enough of those pills and you can actually harm your vehicle. The last thing you need is a bunch more sediment or unknown, dissolved additives in your fuel.

There actually are proven, sensible ways that you can maintain good gas mileage, however. Good car care and consistent preventive maintenance are the keys to good fuel economy. An oil change at McPherson Automotive in Du Quoin and a new fuel filter, when needed, will keep your engine running efficiently, which will translate to good fuel economy. It may be mundane, but it's solid, proven advice.

So be smart. Listen to advice from qualified McPherson Automotive professionals, and stay away from unverified “magic” and conspiracy theories. Your wallet—and your vehicle—will thank you in the end.

McPherson Automotive Service Tip: Why Synthetic Oil Is Good For Your Vehicles

Hello IL! Today's vehicle care topic is: Synthetic Oil vs. Petroleum Based Oil. Synthetic motor oil is a substitute for petroleum based oil. If you aren't currently using it, why not? Synthetic motor oil maximizes engine power and fuel economy. To see why, we'd need a microscope, so we'll have to settle for using our imaginations. The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is slipperier, a pile of pencils or a pile of marbles?

Synthetic motor oil lubricates better because there's less friction. This results in myriad benefits: better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn't sludge up like conventional oil so it prevents those small oil passages from clogging up. (We see that too often at McPherson Automotive in Du Quoin.)

Some manufacturers are extending oil change intervals for many models. The added protection of synthetic oil covers you for these longer intervals. Talk with your McPherson Automotive service advisor about how you drive in and see if he thinks you can benefit from synthetic oil for your vehicle. Also ask about the appropriate oil change interval for synthetic, because it may very well be longer than for conventional oil.

Most of us have a busy life and occasionally miss an oil change; go ahead, admit it. Since we're not perfect, doesn't it make sense to use a motor oil that's got your back?

What about price? Petroleum based oil may appear to win out on this point, but let's consider all the facts. Although synthetic oil costs more, it lasts longer, protects your vehicle engine better and increases fuel economy. You'll likely save money in the long run. If you're serious about making your vehicle last longer, consider using synthetic motor oil.

Give us a call.
