So I'm assuming that just because it has the "minimum" cert rating that it is sufficient to use.

How about, how does this oil suspend soot and other agents that increase engine wear. You you can use just about any oil you want, but does it actually perform the duties that a diesel engine requires for efficient and lasting reduced wear operability?

If what some are saying is correct? Why even consider Delvac 1 and the likes?
