My dad was using AMS ATM 10w30. Since then I have purchased his truck and I'm thinking of switching to AME 15w30. Not sure, what does everone else run?? Do I really need AMS oil, rotella is a lot cheaper!
rotella will foam up badly in a powerstroke... the high oil pressure causes the oil to foam.... bad things happen then. stick with delo, ams, valvoline, and many other good ones.
i use rotella in everything we have, d7h dozer, l785 skid steer, jd tractors, but not my ps. read way to many reports on problems it causes in the powerstrokes due to the high pressure oiling system. dotn want to even risk it. i even use it in our 92 7.3 non turbo farm truck but not the powerjoke.
