Change to Mobil 1 5w-40 Oil For are C43s????????

The 5W-40 ESP, Emissions System Protection, has less impact on the emissions system which the auto maker must warrantee for 10yrs, than the 0W-40 European Formula.
The reason it has less impact is because the additives are reduced. Those additives are the wear inhibitors.

I would love to run the 0W-50 but the high levels of wear inhibitors would hurt the cats (also mentioned in the FAQ)..
They are using 0W-40 at the AMG Academy at the end of last year. I have 100k on my car and plan to stick with it.
