The General Rule for Full Synthetic Oil

Most vehicles running full synthetic oil can go between 7,500 and 10,000 miles between oil changes. Many newer models can stretch that interval all the way to 15,000 miles. That is a significant improvement over the old 3,000-mile rule that applied to conventional oil. Full synthetic oil is engineered to last longer and protect your engine better under a wide range of conditions.

Road Conditions Can Affect Your Oil Change Interval

Not every driver puts the same kind of miles on their vehicle. Frequent short trips, dusty roads, extreme heat, and heavy towing are all considered severe driving conditions. Under these circumstances, your oil breaks down faster and needs to be changed more often. If your daily drive involves a lot of stop-and-go traffic or unpaved roads, you may need to shorten your oil change interval accordingly.

Do Not Ignore an Overdue Oil Change

Even with full synthetic oil, pushing well past your recommended interval is not a good idea. Old oil loses its ability to lubricate and clean your engine effectively over time. That can lead to buildup, increased wear, and costly repairs down the road. Staying on top of your oil change schedule is one of the simplest ways to extend the life of your vehicle.
