You've heard that expression, change is good.  When it comes to your vehicle's oil, change is not only good, it's vital for the health of the engine.  But there's one question that puzzles many drivers: how frequently should my vehicle's oil be changed? There is not one simple answer, but here are some guidelines that will help. It used to be pretty much a rule of thumb that vehicles got their oil changed once every 3 months or 3,000 miles/5,000 kilometers.  But times have changed.  Oil formulations have gotten better and engine designs have made longer oil change intervals possible.  Most experts advise you to read the recommendations that come from the manufacturer that designed and built your vehicle.  Their designers and engineers know more about your vehicle than anyone else.  They spell out their recommended oil change interval and type of oil in your owner's manual.  Many automakers say you can go at least 5,000 miles/8,000 kilometers betw ... read more

You've probably noticed how much easier it is to see when you're driving in the daytime as opposed to at night. It's one of the main reasons about half of all fatal vehicle accidents happen when it's dark. That's why it's important that your vehicle's headlights are in top condition and working the way they should.  That means that they're aimed correctly and producing the amount of light they are intended to produce. For many years, headlights were a standardized size and shape.  They were what is called a "sealed beam," and when you needed to replace one, it was pretty simple.  You just took the old one out and plugged a new one in.  But now there are hundreds of different types of lighting systems on vehicles, producing light with such illuminating technology as light-emitting diodes (LEDs), halogen bulbs, high-intensity discharge (HID) bulbs and more.  Some vehicles have systems that turn your lights in the direction you turn your steering wheel so you can ... read more

For those of you in Rockville, MD who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same fuel economy. The turbocharged version makes over 350 horsepower.So what are the differences from a conventional engine?The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder ... read more
