Oil Change

Yes. You should I use synthetic motor oil?

For years the accepted oil change interval (as per the carmakers) has been every 3 months or 3 thousand miles, whichever comes first. Why? Because the oils of yesterday degraded and broke down when left in the crankcase environment for longer than the prescribed interval.

Ford Motor Company has followed GM into the extended oil change interval march. In March 2007, Ford announced that they are revising engine oil change intervals to every 7500 miles. The reason? Quoting the article from the Associated Press dated March 22nd, 2007:

Rotating your tires helps to increase the life of your tires and helps to keep your vehicle safe. Each manufacturer will recommend different requirements for how often you should rotate your tires, but typically it is between 5,000 to 10,000 miles.

Total car care

The best thing that you can do to extend the life of your car and potentially save yourself a bundle of money is to have your car serviced on a routine basis. All car manufacturers have a schedule of recommended service for each vehicle they sell. Follow this schedule. The best place to have work done on a new vehicle that is still under warranty is the dealership. On cars without a warranty, it is best to find a reputable independent shop and have it serviced regularly there.

Drive Axles

An axle that is driven by the engine is called a drive axle. Modern front wheel drive cars typically combine the transmission and front axle into a single unit called a transaxle. The drive axle is a split axle with a differential and universal joints between the two half axles. Each half axle connects to the wheel by use of a constant velocity (CV) joint which allows the wheel assembly to move freely vertically as well as to pivot when making turns.

In rear wheel drive cars and trucks, the engine turns a driveshaft which transmits rotational force to a drive axle at the rear of the vehicle. The drive axle may be a live axle, but modern automobiles generally use a split axle with a differential.

Some simple vehicle designs, such as leisure go-karts, may have a single driven wheel where the drive axle is a split axle with only one of the two shafts driven by the engine, or else have both wheels connected to one shaft without a differential (kart racing).
