Shit I wish my oil changes were 37 bucks!!! I do my own and it costs more than that for the materials!! Mobil 1 filter and oil will run about 50 bucks. My Ram holds six quarts when I use the oversized Mobil 1 filter (meant for a Ford engine) and it gets really expensive, really fast. Of course I dont buy it at Wal Mart so that could be part of it, I always go to O'Screwme's or Awful Zone, never seem to remember that WalMart now carries Mobil1.
I wont let any of those douchebags at a lube shop or stealership touch my oil. I worked in a few Kwik Kar stations about 6 years ago as a state vehicle inspector, and after seeing what those waterheads did to some vehicles, I am damn sure not taking one of my vehicles to them. I feel safer letting the oil go over 3K miles if I dont have time to change it than to risk my car to them.
