Yep, I got the same letter from M-B about synthetic oil. I have been using Mobil 1 since new anyway on my 2000 E430. My question is this: Will they pay for the synthetic oil when the car is serviced under FSS? I have been taking my own oil or paying extra from the dealer for Mobil 1.
The weights they recommend are kinda strange. I cannot find 15w 50 Mobil 1. Must be some kind of bulk thing. I have been using 10w 30 from the bottle.
