Just got my first oil change today at the dealership. I asked them what kind of oil they put in, and the mech said 15W-40W. I said good, because I use Rotella 15W-40W in my farm tractor, and also used it in my last two Dodge w/Cummings engines. He then told me that I shouldn't use Rotella because it foams and causes the injectors to "dry fire" and damages them. Hmmmm??? Has anybody else ever heard that or is it basically a bunch of hogwash? No intention of starting oil wars, this is just my first Powerstroke and I'd like it to be a positive experience.
