According to a top Cummins tech, only Amsoil MTF 5w-30 and the factory Mopar stuff is what you can run. they are the only 2 that won't void warranty. 5qts is about the norm. Amsoil MTF is also rated for up to 150K per change. Take out the bottom center PTO cover bolt for draining then pull the PTO cover and suck the rest out.
