Mobil 1

Check out the diesel forum on If you'll look on the archives, there has been numerous and verbose discussion on the merits of Synthetic vs. Dino Oil. Mercedes also has a list of "approved" engine oils which they have published. I'm not sure about Amsoil, but I know that Rotella does NOT make the list. Also, be very careful when purchasing synthetic oil as recent changes in advertising regulations have allowed manufacturers to sell an oil as a synthetic when the majority of the oil stock is actually mineral oil.

Mobil 1, Amsoil, Bardahl and a few others are the only "true" synthetic oils available.

I, and many others on the forum have had good results utilizing Mobil 1.

Good Luck,
