Last night I hit my oil change mileage so I stopped by a place today to get that done, and the guys inside (and this isn't a local hick joint or anything) told me that they couldn't change my oil because they didn't have 0W20W oil, and that only Honda had that type. When I told them that I'd read on this site that the 5W/20W was also ok they said I'd be violating my warranty and would probably blow my engine. They also claimed that nobody but Honda makes the oil type that I need. Do most of you get your oil changed by a honda service center? Anyone had this problem before?
