epa has been in a war against this for a long time. Very soon, no oils will have that much zinc.

Quoted from epa documents...

" The useful life definitions for 2004 and newer heavy-duty diesel engines are included below from the CFR. As you can see, the useful life is defined both in terms of mileage and years of operation. For example, the useful life definition for a heavy heavy-duty dieselvehicle is 10 years or 435,000 miles, whichever comes first. In the case of a dump truck, it may be that the vehicle will reach 10 years of operation (i.e., full useful life) prior to reaching the mileage defined useful life of 435,000 miles."

According to them, 435,000 miles is all an engine should last.

Rotella T Triple is roughly 1200 - 1300 ppm Zinc according to various sources I have found. Is there a better oil to run with a higher zinc count? Or stick with Rotella T Triple and your recommended gear lube that I have been using.
