Correct viscosity is far more important than the anti-wear additives.

At 180*F 10W-40 is around 25 cS, and a conventional 10w-30 is around 18 centistokes.
At 212*F 10W-40 is around 15 cS, and a conventional 10w-30 is around 10 centistokes.

Those are the factory recomended oil grades, with 10W-40 really not for cold weather because its still a bit too thick at 180*F.

For higher than 800 ppm in zinc in a conventional oil

it's pretty readily available.
One of the better options available for a relatively high ZDDP package in a conventional oil. Plenty for stock engine, stock spring presures. etc. Probably group II base oil. No API cert, and obviously Ford won't recommend it for cars with cats due to the potential long term warrenty issues.
Here's an oil analysis

Thank you for the information. I did a little more research in both the ford oil SDS and the Valvoline SDS. In the Ford oil, there is just the basic zinc dikasdhfktoflghgdfjfdjfphate.

in the Vavoline there are three. (technically)

the ford has 1.22% by wt. which equals around 12,200ppm of zinc.
the valvoline has 1.44% by wt. which equals around 14,400ppm of zinc.

Really no change at all. The Ford is 29.99 and the Valvoline is 33.99.
So the next oil change I will be getting the ford oil for my mopar and save 3 bucks. :thumbsup:
