East Cobb BP
This is my favorite place to get oil changes. I've had other work done there too, and that was also good, though I have a regular mechanic that is closer to me. One thing that distinguishes this place--they are a full service repair garage with tire service--and separate drive up bays that do only oil and fluid changes. So you can get a quick oil change without an appointment or a big wait, but some extra competence and resources that come with a full service shop.
