When the leaves fall, you might take a sightseeing trip to see them at peak color.  Or you may simply live in a spot where there are a lot of trees.  When those leaves get wet, you'd be surprised to learn just how slippery they can be.  We all know ice is slippery to drive on.  What causes tires to slip on ice is a thin layer of water that comes between the road and your tires.  Wet leaves can have the same effect.  The surfaces of leaves are super slick when they're dry, even worse when you add a little moisture.  There's one other thing about leaves.  They are smaller than each tire's footprint, so your tread grips the pavement with uneven traction. One study showed that your stopping distance can more than double on a surface covered with wet leaves when compared to that same road when it's dry.  Double! That can spell trouble.  So if you find yourself heading into an area with wet leaves on the road, slow down before you get into a ... read more

If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent.  But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust.  If there's too much, it means there's a problem with the mixture of fuel and air.  The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency.  It does this constantly.  Many vehicles have multiple oxygen sensors.  Some have one close to the engine, another close to the muffler.  Two measurements are better than one since they allow readings to be more accurate.  You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail.  One thing that can damage them is contaminat ... read more

If your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you.  No, really, it is.  So listen to what it's saying and you could avoid a much more costly repair down the road. A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on.  One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels.  Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems.  Think of it.  Hydraulic power steering has many components that need to work in tandem.  The power steering fluid may be too old and contaminated.  Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening. Other causes of grinding while turning can be problems with the suspension in the front.  Yo ... read more

If your windshield wipers are streaking and chattering when you turn them on in the rain or snow, it's time for a little "blade renewal." And when it comes to new wiper blades, there are some new designs that are worth a look. One of the latest is called the beam blade.  It's different than conventional blades you might be used to.  Instead of a metal frame and a rubber blade that slides in the frame on a track, the beam blades have an enclosed spring-steel band that allows the rubber wiper to conform to the windshield glass shape much more tightly.  There are some key advantages to beam blades, which is why many vehicle manufacturers are making them standard on their latest models.  For one thing, they work well in all weather conditions, including the heat of summer and the icy, snowy cold of winter.  Since there is no separate frame, snow and ice can't form in gaps like conventional wipers and prevent the blade from clearing your windshield.  Many beam ... read more
