So any learned info on these quick oil change places ?? Ive looked them up and opinions galore but no scientific info so I thought Id ask the brain trust that resides here, what say you??This may be a silly question, but performing the oil changes yourself does not void the warranty, correct? Of course with the assumption of using the correct oil and no problems arise as a result of doing it yourself. I'm sure a sketchy dealer could try to pull something if an issue did come up that can be associated with performing your own oil change.
