Common questions
How long does an oil change take?
Most oil changes are done while you wait or within the same visit. If the shop is full, we will give you a realistic pickup time before we start.
Do you use synthetic oil?
Yes, when the vehicle calls for it or you ask for it. We match the spec in the owner's manual rather than upselling a grade you do not need.
