CalRecycle’s new motor oil campaign, Check Your Number, urges Californians to check the recommended oil change interval for their car in their owner’s manual. They’ll likely save time and money in service costs and do the environment a big favor — without hurting their car or compromising auto performance in the least.

The old standard of 3,000 miles is woefully out of date and no longer applies to most cars. Many cars, even older models, can be driven up to 5,000, 7,500, 10,000, and even 15,000 miles before needing an oil change.

By volume, used motor oil is one of the largest hazardous waste streams in California: Almost 115 million gallons are sold in the state each year. While about 70 percent is collected after use, it continues to be a serious environmental problem because it is insoluble and contains heavy metals and toxic chemicals. It makes its way into lakes, streams, and oceans via the storm water system and endangers fish, waterfowl, insects, and other aquatic life. In addition, one gallon of used motor oil can foul the taste of 1 million gallons of water.

Drivers can do their part to help the environment by simply looking up the recommended oil change intervals for their cars and changing their habits accordingly. Advances in modern engines and improved oil formulas have made the 3,000-mile oil change obsolete. Under normal driving conditions, cutting back to the automaker’s recommended intervals will not affect your car’s engine, its performance, or your warranty.
