Sad, but all too true. I don't change my own because I don't like effort for the filter change. I use Grease Monkey because I know they have had training on my car (certificate on the wall, checked and verified), I make them use quart containers of oil (Mobil One 0W-20) and visually check them. I always have it done by the same guy, and he
knows I am fussy. (Makes a tip, too!). Because I am fussy, they don't give me the usual hard sell for all the other stuff, either. They just show me the filter, etc. when they think it looks bad, and let me decide -- no arguments.
Actually, I like them -- convenient, fast, and high quality. (No, I don't work for them.)
