ok, so contemplating using a 0w40 or 5w40, what is the benefit from going to this grade from previous 5w30 oils?
from what I can see the 5/0w40`s are Euro spec`d, is that a plus or negative for this SC engine?
I see a lot of people using T6 diesel oil, what is the benefit of that running in a gas engine?
keep in mind low OCI`s @ 3k for this truck.
