The Rotella syn was rated CI-4, not CJ-4. My point was that the Rotella dino was the only CJ-4 oil tested and was the "worst" ranked (read the text, not the reference number). Would love to see the same test with ONLY CJ-4 oil (because that's what we have to run, at least until our DPFs fall off). That would mean more to me than a mix of types.
