Car care myths
- Despite what oil companies and quick-lube shops often claim, it's usually not necessary. Stick to the service intervals in your car's owner's manual. Under normal driving conditions, most vehicles are designed to go up to 7,500 miles between oil changes. Changing oil more often doesn't hurt the engine, but it can cost you a lot of extra money. Automakers often recommend 3,000-mile intervals for severe driving conditions, such as constant stop-and-go driving, frequent trailer-towing, mountainous terrain, or dusty conditions.
