Manny, I just went to the site and inputted the information for my 2001 E320 and it correctly recommended Mobil 1 0W-40. When I inputted the information for my 1991 300TE it recommended Mobil 1 0W-30 for above 0 deg. C. Yikes!! I wouldn't use that in this vehicle on a dare. I wonder why the site wouldn't recommend Mobil 1 15W-50 for my car which would be in line with MB's original viscosity requirements? With all the recent talk about big oil being in collusion with each other, maybe they are conspiring with MB to sell more vehicles by causing old MB's to expire Mark
