So far I've chickened out at doing the oil change myself. We only do it once a year (roughly 3-4k miles), and so it's just gone to the shop to be done. I had priced out the kit from atlantic british, and the extra the shop charges is pretty reasonable for labor (total for oil change has been in the 175 - 200 range, vs. 175 for the kit from AB.) Are folks managing to do these for far less using the mobil 1?
