Oil Changes

To make one quart (one liter) of motor oil, 43 quarts (43 liters) of crude oil are required. Is it better, then, to change the oil in your car’s engine less often than the recommended 3,000 mile intervals, and therefore save oil and money? Or is it better to maintain the recommended oil change schedule, to keep your engine running longer?

New York Yellow Cab ran an experiment in which they changed the oil in their cars half as often as the manufacturers recommended. They found no difference in engine life.
