My 1st post here, been reading for quite a while though. I'm at a loss of what to do. The more I read, the more I realize the less I know. I have a 94 Dodge Cummins, 95,000 miles, drive the truck about 6000-7500 year, mostly on trips. Highway miles until the forest roads. I have been using the Delo 400 CI4+
So when the CJ came out, I read I should stay with a CI4+ if available. Was going to use the Amsoil 15w40, but then decided on the Shell Rotela 5w40, but then thought about the Delo 5w40, but then read about the Mobil 1. I guess they are all good. I only want to change the oil once a year. I don't have a specific question, just want some additional advice. Thanks, Ken
