Ouch. I'm glad I change my own. It's very easy with the filter mounted at the top of the engine. I buy the fleece filter in the mercedes box from the chrysler dealer for $21.99. Eight quarts of mobile one at 4 something a quart. Ten minutes of time. Priceless. I actually make buying the oil less painful, I buy a quart whenever I go to the parts store for wax or whatever and over time you never know you spent $40 on 8 quarts of oil.
