I was reading on the 2005 and up mecedes engine gas and diesel,They can't run the good oils like the 617.95X or like my gas engine.I run diesel oils in both as I want the protection that comes with 15w40 rotella.
Newer engine must have finer tolerances as nothing is over 30 weight.To their diesel have particulate filters whick must clog with the calcium,phospros,and sulpher. in the good oils.
I wonder will these engine hold up on mileage?
Bluetec and CDI's lets see how many miles you get.
