Yes, people wait that long, I was being satirical, some people don't change their oil either, they drive their vehicles til they drop.Anyone who goes by the manual or the oil life monitor. Probably anyone who maintains a fleet. I did my first change at 5k and am planning to change it every 5k into the future, mostly because it's a nice round number easy to remember. 10k would probably be OK, 7,500 would be fine, but it's so cheap and easy, why push it?
