<VV> How MUCH Phosphorus and Zink?

[J R Read_HML]

I'm unable to find Mobil 1 Turbo Diesel Truck  5W40 on the shelf locally. 
That is what I've been using.  It has 1100 PPM of Phosphorus and 1200 PPM of 
Zink.

What is the minimum we should be using in Vair engines?

There is a Mobil 1 High Mileage in three viscosity choices - 5W30, 10W30, 
and 10W40 - which has an SL rating, but the counts are lower.  900 
Phosphorus and 1000 Zink.  Is that one sufficient for Vairs?
