DEBUNKED – The 3,000 Mile Oil Change Is A Myth: What’s Being Said



Needing to change your car’s oil at 3,000 miles is a myth. Many cars today can go longer without affecting engine wear. Automakers are regularly recommending oil changes at 5,000, 7,000 or even 10,000 miles based on driving conditions.

Yet research conducted by the California Integrated Waste Management Board (CIWMB) shows that nearly three-quarters of Californian drivers change their motor oil more often than automaker recommendations. Following the 3,000 mile myth generates millions of gallons of waste oil every year which can pollute California’s natural resources.

Do your part to help keep our earth green. Always check your vehicle’s user manual for guidelines on when to change your oil. It will save you money, time and help the environment too. And that’s a change we can all get behind.

What’s Being Said About the Oil Change

“A driver whose fuel tank is still half full wouldn’t empty the tank just to refill it. This same logic applies to oil changes. We should not waste motor oil that still has life.”
– Executive director of GM Service Operations, December 2006

“Although oil companies and quick-lube shops like to promote this idea [that engine oil should be changed every 3,000 miles], it’s usually not necessary. Go by the recommended oil-change schedule in your vehicle’s owner’s manual. Most vehicles driven under normal conditions can go 7,500 miles or more between oil changes. Some models now come with a monitoring system that alerts the driver when the oil needs changing. Depending on driving conditions, these can extend change intervals to 10,000 or 15,000 miles.”

“…for the vast majority, 5,000-mile oil changes will help your engine last to a ripe, old age.”
–Tom and Ray Magliozzi, hosts of NPR’s Car Talk, on MSNBC, April 17, 2006

“Most manufacturers now recommend changing the oil every 7,500 miles. We recommend doing it every 5,000 miles because we tend to be more cautious about protecting the engine. Very few people recommend changing the oil every 3,000 miles anymore. It’s just not necessary, and the environmental cost is too high.”
–Tom and Ray Magliozzi, hosts of NPR’s Car Talk, in the Detroit News, April 6, 2005

“Conventional wisdom has held that the oil should be changed about every 3,000 miles. This notion has been ingrained into people’s heads for decades, in part as a marketing ploy by oil companies. The 3,000-mile interval made sense when engines used single-grade non-detergent oils. But with the latest oils and car designs, it’s no longer necessary to change oil that often under normal driving conditions.”
–Steve Ritter, in Chemical & Engineering News, March 13, 2006

“Synthetic oils, because of their better properties, need to be changed less often, at intervals up to 25,000 miles or more. In the end, the best advice on the type of oil to use and the frequency of oil changes is to follow the manufacturer’s recommendation in your car owner’s manual.”
–Steve Ritter, in Chemical & Engineering News, March 13, 2006

“Most major automakers agree: The adage that you should change your car’s oil every 3,000 miles is outdated, and even 5,000 miles may be too often.”
–Tom Krisher, Associated Press, in the Deseret News, March 26, 2007

“I remember getting my first car (a hand-me-down) and how my father kept telling me how important it was to change the oil every 3,000 miles. A lot has changed since then. Today’s oil is much better, and it can last a lot longer. Here’s what to do: Check your owner’s manual and follow the manufacturer’s recommendation.”
