Are the faithful every-3,000-miles oil changers being unkind to the environment? The California Integrated Waste Management Board is launching a campaign to call the 3,000 mile oil change a myth. Many manufacturers recommend more mileage between oil changes for cars these days. The Automotive Oil Change Association, an organization that represents fast lube companies, is not surprisingly calling the campaign “misleading.” The bottom line is: read your owner’s manual, and dispose of used oil properly.
