Mystik Full Synthetic Oil

[Crewchief47]

Mobile1 no longer contains enough Zinc to properly protect the flat tappets in our engines. (As of the new API spec)
Diesel oils, Redline, Amsoil, and a few others do have enough zinc.
(I suspect Yamalube does also as they sell it for our sleds, but don't know as fact. Hondo may be able to fill us in on that one.)
(Have no idea about the Mystik oils.)

Hope this helps!

So is the zinc content of Mobile 1 lower now or has the specification range been moved and now the zinc is too low???

EDIT: Been doing some research and I see it's a case of both.....
