With the issues that have popped up with the valve train on the Ford 7.3 gas would running a non api certified oil that carries like 1,200 ppm phosphorus and 1,300+ ppm zinc be a good idea? Is it too much ZDDP? Thinking about running Royal purple hps 5w-30 since it has A LOT of ZDDP in it. I’m not worried about warranty issues (not yet)
