Mike,My main concern is CJ-4 oil versus CI-1+. Are folks driving 2nd Generation trucks useing the newer CJ-4 rated oils and is this blessed by Cummins. The bigger question is does it really make a difference.
I had a typo... the discussion is about CI-4+ versus CJ-4.Just what is the diff between the cj1 and the cj4 ? Is it zddp ?
I knew this was coming!Why use old fashioned petroleum oils these days?

Ken,
Your veiled advertisements for a product you're selling are tiptoeing awful close to violating the TDR user guidelines.
I'll stick with Dodge's recommendations thank you very much.

Read John Martin's Technical Topics articles in TDR issues 56-58, about oil formulations. You can read the digital versions on this web site. He was a petroleum engineer for Lubrizol and holds many patents. He did a series of blind tests on a number of oils. Don't waste your money on Amsoil, they rated the same as Walmart.
