Why the 3,000 Mile Oil Change Is A Thing Of The Past.

Find out when you should really change your oil….
Excerpts italicized:


“There was a time when the 3,000 miles was a good guideline,” said Philip Reed, senior consumer advice editor for the car site Edmunds.com. “But it’s no longer true for any car bought in the last seven or eight years.”


Oil chemistry and engine technology have improved to the point that most cars can go several thousand more miles before changing the oil, Mr. Reed said. A better average, he said, would be 7,500 between oil changes, and sometimes up to 10,000 miles or more.


The California Integrated Waste Management Board ran public service announcements for several years about “the 3,000-mile myth,” urging drivers to wait longer between oil changes. Although the information is a few years old, the board has a list of cars on its Web site and how often they need oil changes. The concern is not only the cost to drivers, but the environmental impact of throwing away good oil, said Mark Oldfield, a recycling specialist for the agency.


Rather than picking a number, Mr. Sutherland said, he recommends following what your owner’s manual advises. I checked the manual for our 2007 Mazda5 and had to determine if my typical driving included a lot of stop-and-go driving, short distances, extended idling, muddy, rough or dusty roads or really humid or cold temperatures.


Hmm. Yes, to short distance and stop and go. So that meant I should get the oil changed every 5,000 miles. If I did a great deal of longer-distance highway driving, it would be every 7,500.


Some people remain attached to the 3,000-mile oil change and have a hard time trusting the recommendations in the owner’s manual. If you’re one of those skeptics, you can send your engine oil out to be analyzed. Blackstone Laboratories in Fort Wayne, Ind., one of the best-known places for engine oil analysis, will send you a free kit.


You send back an oil sample and for $25, they’ll tell you all sorts of things about your car.
Still, some people stick to the 3,000-mile changes, because “the Jiffy Lubes of the world have done a good job convincing people,” Mr. Martin said


It’s not just the fast oil change outlets. My sticker from my trusted mechanic states that I’ll need a change in 3,000 miles or three months. But Jiffy Lube, the largest quick oil change company in North America, is now under pressure to change its automatic 3,000-mile recommendation.
