How often should I change my oil in my light duty vehicles?
The old rule was you should change your oil every 3 months or 3,000 miles. This is no longer the recommended interval especially for gasoline engines, and if you still stick to that schedule you’re wasting money and using an unnecessary amount of oil. With the newer synthetic oils most vehicles can go at least 5,000 miles between oil changes. The best way to determine when your oil needs changing is to consult the owner’s manual of your vehicle.
