3,000 mile myth
From Infogalactic: the planetary knowledge core
The 3,000 mile myth refers to a common belief, particularly in the United States, that all cars should have their motor oil changed at least every 3,000 miles (4,800 km) to maintain their car engine correctly. 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.[1][2][3][4]
