If I use synthetic oil how often should I expect to change the oil. The dealer is telling me every 3,000 miles, friends with similar vehicles say that is much too often, who is correct?

Answers from the Automotive Experts

Stephanie Gutierrez, Marketing at Victory Auto Service & Glass Driving with synthetic oil in normal conditions, you should be able to go 7,500 miles between oil changes. The reason I wouldn't recommend longer than that is that the average person doesn't pay much attention to their vehicle and one of the biggest benefits to regular oil changes outside of the oil change itself, is that the technician gets to take a look at your vehicle and see how it's doing. If you wait 12,000 miles between oil changes, even if your vehicle can make it, there is a chance there may be issues with your vehicle that you won't notice. Regular, frequent oil changes are the best way to keep a pulse on your vehicle's health.

Cherie Watters, President of Sales and Marketing at Synthetic oil is meant to last much longer. Go to the manufacture web site and check the recommended maintenance for your car. 3,000 miles does seem too often but check the web site to be sure.

Amanda J. Pierce, MBA Rae, There are many synthetic oil that can carry you to 5000 miles or even 7500 miles, make sure you follow the manufactures recommendations.

Amy Mattinat, Owner and Author at Auto Craftsmen Ltd Using full synthetic oil - if you drive mostly highways, you could go 7,000 to 8,000 miles depending on where you live. If you drive mostly in the city [stop and go driving] I would recommend having the oil changed every 5,000 miles

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube Consult your owners manual

Helaine Kurot, Owner/Technician at 360 Automotive Greetings, There are many factors that go into determining how often you should change your oil. Generally, they say 5000 miles on synthetic oil. Depending on your driving conditions, this may not work for your vehicle. If you do a lot of idling, or are sitting in traffic for extended periods of time, you may not put many miles on the vehicle, but you would want to change to oil more frequently. Oil will also break down over time, so changing it every 6 months to a year reguardless of mileage may also be a good idea. You may also want to ask what brand and weight of sythentic oil they are using, as not all synthetic oils are the same. Make sure the oil being used meets the minimum requirements listed in your owners manual.
