How Often Should I Change My Oil?

Richard Cordes, owner of European Sales & Service, Inc. Mercedes Benz, a Diamond Certified company, says it’s a mistake to wait 12,000 to 15,000 miles between oil changes, as some auto manufacturers now recommend. Longer intervals between maintenance visits mean your shop might not be able to detect small problems early, which can lead to big, expensive problems later. The more miles on your car, the more important regular oil changes and check-ups become.

Mr. Cordes says oil is inexpensive, and by changing it at least every 5,000 miles, you’re buying “cheap insurance.” He also reminds you to check the oil change requirements of any after-market extended warranty you’ve purchased. Some companies will void your warranty if you don’t have regular lube and oil changes every 4,000 miles or four months, whichever comes first. Check the fine print to see exactly what your policy says.
