Most technicians agree that changing the engine oil and filter on a regular basis is the single most important maintenance service for your car, truck or SUV. Refer to your car’s owners manual for the factory recommendation on oil changes.

If you are often in stop-and-go traffic, city driving, or go on frequent short trips, you may want to change your oil more often. The amounts of time you can wait before changing your oil tends to differ greatly between conventional and synthetic oils.
