Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.Remember that marbles and ... read more

No matter what vehicle you drive, when certain things break, you have to make a decision.  Should I get it fixed now, later or never?  Air conditioning is one of those things.  You can certainly live without air conditioning, but it sure is nice to have on a sweltering day. Let's say your air conditioning breaks in the fall and you live in a climate where it gets quite cold in the winter.  Should you get it fixed now, wait until spring since it won't get warm until then or maybe not get it fixed at all? That can be a tough decision.  There are several reasons air conditioning in vehicles break.  One is fairly simple: It could be an electrical problem, perhaps a relay or solenoid is not turning on the system.  It's also a fairly inexpensive repair and doesn't require hours of labor. Or, the problem is that the coolant has leaked out.  Your service facility can find the leak and replace the parts that are leaking.  With a refrigerant recharge ... read more

There's a gauge that many vehicles have that says RPM on it.  And there are a lot of people who either don't pay any attention to it or don't even know what it is. Here's why it's a good gauge to know about. It's called a tachometer, and that "RPM" label means it is measuring how many revolutions per minute (RPM) the engine is turning.  Automotive experts know that a vehicle's engine can be damaged if it turns too fast (revving too high) or too slowly ("lugging" the engine). A tachometer (sometimes called a tach) is almost a "must-have" gauge for vehicles with a manual transmission; the driver has to manually change gears; the tach helps the driver know when revolutions are in the optimal range. Some say you don't need a tachometer if you drive a vehicle with an automatic transmission. It's true that most drivers of automatics don't even look at it.  But there are times when paying attention to the tach can help you prevent an expensive repair. Here's a good example.&nbs ... read more
