I went to Grease Monkey to get an oil change, but it was almost time for them to close so I didn't get in. However, I was worried about my car because it had been too long since I had an oil change, so the guy offered to check my oil just to make sure it wasn't low. I went back the next day for an oil change and they were very helpful, pointing out problems that may be happening with my car even though they couldn't fix them (and thus make money off of me).
