The 3,000 mile myth refers to a common belief, particularly in the United States, that all motor vehicles should have their motor oil changed at least every 3,000 miles (4,800Â km) to maintain their car engine. Efforts are under way to convince the public that this is not necessary and that people should follow the advice given in their owner's manual rather than the advice of oil-change businesses. With modern synthetic oils and new tests such as BMW's LL ( long Life ) oil specifications, most current cars can go over 6000 miles ( 10.000 Km ) before needing an oil change, even most modern conventional, also called Mineral oils can go more than 5 or 6 thousand miles before needing an oil change.
