Stop Changing Your Oil Every 3000 Miles

Oil chemistry and engine technology have evolved tremendously in recent years, but you'd never know it from the quick-change behavior of American car owners. Driven by an outdated 3,000-mile oil change commandment, they are unnecessarily spending millions of dollars and spilling an ocean of contaminated waste oil.

Although the average car's oil change interval is around 7,800 miles — and as high as 20,000 miles in some cars — this wasteful cycle continues largely because the automotive service industry, while fully aware of the technological advances, continues to preach the 3,000-mile gospel as a way to keep the service bays busy. As a result, even the most cautious owners are dumping their engine oil twice as often as their service manuals recommend.
After interviews with oil experts, mechanics and automakers, one thing is clear: The 3,000-mile oil change is a myth that should be laid to rest. Failing to heed the service interval in your owner's manual wastes oil and money, while compounding the environmental impact of illicit waste-oil dumping.

Scared Into Needless Service -Part of the blame for this over-servicing lies in our insecurities about increasingly complicated engines that are all but inaccessible to the average driver. Pop open the hood of a modern car, and a mass of plastic covers wall off the engine. On some vehicles, the only thing an owner can easily access is the oil cap.

The 3,000-mile myth is also promoted by the quick lube industry's "convenient reminder" windshield sticker. It is a surprisingly effective tool that prompts us to continue following a dictate that our fathers (or grandfathers) drummed into our heads: It's your duty to change your oil every 3,000 miles — or your car will pay the price. But as former service advisor David Langness put it, the 3,000-mile oil change is "a marketing tactic that dealers use to get you into the service bay on a regular basis. Unless you go to the drag strip on weekends, you don't need it."

Agree 100%. I send a sample of my oil to Blackstone Labs, and even with 9 months and 8,000 miles on it, they said it was still fine, and I could push to 10,000.

The only car I've every changed the oil on nearly that often is the one with a turbo on it. The rest I wait 5-8000k.
