scuba, I don't know where you went, but if it wasn't Express Oil Change, I highly recommend that you try them. Unlike my experience with the other 30-minute oil change place, they will do what costs you the least amount of money. Not that you can't still go to Scotty's, but if your "diagnosis" wasn't from them, your estimate may be higher than it could be. I've used Express since they opened with great results, and it's not just me. While waiting, I hear them go over items with other customers and it always seems to be in the customer's favor.
