I agree with Scott Longston. Wonder if it would be a good idea to put all oil-related threads into their own forum?

I hate to throw more oil on the fire, but Mobil's website says that Mobil 1 is compatible with gasoline and diesel engines a number of times.

I see that Mercedes-Benz recommends Mobil 1 on their newer products, so that's promising.

Also, modern Mobil 1 more than likely exceeds the requirements of the 80s and earlier passenger car diesels.

I think if you look at ANY brand synthetic, you will see a "C" rating. Whether or not this oil is up to Mercedes latest standards, I don't know. The newer FSS cars probaly have stricter standards. Oil ratings do become absolete over time. Obviously at some point a CH rated oil will be replaced by CI. This doesn't mean your SOL if your car originally called for CH, because the CI would superceed it.
