Correct me if I am wrong someone, but I think the only "REAL" thing they do is put a can of BG-44K in the gas tank... and that is a fuel injection cleaner.. which I priced at $22 a can. I can dump that in myself. The only reason I had them go ahead and do the oil change is because it was in the shop getting the stress crack in the windshield replaced... usually I'd just do that myself but I was feeling lazy this time around.
