I have frequently borught my vehicle to the dealership with my own Mobil 1 oil and filter (mann or hengst), & paid only about $22 for labor, as an "express oil change" where the car is not checked for anything else. Last week, I had to go on a long trip & fss was in the negative territory, so I took the car to an indie shop 15 minutes away, which only does mercedes, and I let him provide oil & filter since price increases significantly if you provide your own. I was charged as follows: labor: $25; 8 qts Mobil 1: $60; and filter:$23.10, for a total of $108 before tax. Materials cost much more than I would have paid for my own oil & filter. However, I appreciated the convenience, since my wife waited while they did the work. I just wondered if the filter was made from titanium or some other exotic metal, since Phil sells them for about $10 or less!
