Most technicians agree that changing the engine oil and filter on a regular basis is the single most important maintenance service for your truck, car or SUV. Refer to your car's owners manual for the factory's recommendation on oil changes - or if you are an I-Phone user, download our FREE I-gAAuge application for your maintenance schedule. 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.
