My uncle last Thanksgiving: Yeeeeeeep. I haven't changed my oil in about five years. I just change the filter every three months. Oil doesn't go bad. It will lubricate forever. You just have to keep it clean.
I go to this place called Oil Express. They say 10 minutes and they rough ridin' mean it. I go there when I'm driving by and see there's no wait. I like it because I don't need to spend more than 10 minutes dealing with that crap.
