Gentlemen,
First, the reccomened synthetic oils for the diesel listed in the current MB lubricant specs, address's only the oils submited to MB for testing. The factory told me on the phone there are other high
quality synthetic oils out there, but they didnt submit them to us for testing, subsequently, there are few oils listed on the supplemint. I personely use Royal Purple 10w-30 in my 1999
E300 Turbo, and regularly change it at 13k. I now have 49k on the vehicle and only had one warranty problem..the glow plug control went bad about 20k ago. I get 32mpg at hwy speeds averaged at 65mph, 36mpg at 55-60mph. By the way, the factory told me the car came with 5w-30 Castorl dino oil from the factory.
Everyone who owns a Benz should be grateful they own the safest car made..I was clobbered on the left side car by a Suv the other day, and walked away with few injuries..The suv that hit me, well all (3) of them went to the hospital.
