Sorry if this is an old topic.
Couldnt find anything on it straight off.
Yesterday i was told by an aquatance that Rotella had changed its formula.
He said they have reduced the amount of zinc to 1/10th of the old formula.
Soooooo. is this [censored]? Or is he speaking truth?
Word is its even bad on older engines now. (diesels and such.)
Ive used Rotella 15-40 in our Ford powerstroke, our 4 wheelers, and motorcycles for years.
Is it still safe?
Any zinc additives out there if it is indeed deficient now???
Not trying to start rumors, just trying to get the facts.
Thanks!!
