I booked an appointment today to use the same coupon for $8.88 oil change and was told my car takes synthetic oil so it wouldn't qualify for that deal which is fine. But I questioned why I took the same exact car in last time and they didn't tell me that. The guy checked his system and told me they didn't use the right oil last time. I go to a dealership because I figured they would have more knowledge on cars and won't mess up on an oil change. I left upset without any service being done to my car because I felt my trust in their service department was no longer there and had to drive all the way back to my further, but more trustworthy dealership for just an oil change.
Oh and their wait time for just an oil change is 3 hours and that's with an appointment.
