T6 new or "cooked" flows better cold than delo.
LOLThey say you can go 50,000+ miles with oil filter change and bypass filtration.

I used to run 50k miles on shell t6 in my 05 Oil analisys every 10k and new filter every 10kUse hot shot secret 5w40 or 10w30 and don’t change it for 30k miles. Get an analysis don’t at 15k and you’ll see you still have plenty of life left in it. The oil is a little more pricey but it pays for itself in longevity and time wasted changing oil.

I normally run shaeffers in my vehicles....I'm giving HSS blue diamond a shot and going to uoa it to see how it compares....5-40....
Why is that? The owners manual doesn't say that, and you know they are always overly cautious with their recommendations. I guess I could see if it you lived in a cold climate, since syn's flow better at extreme cold temps. I've never used a syn oil in any of my diesel's, never been an issue. Rotella T4, OEM filters in my Ram.You have to run synthetic in these
If you can find 5w40 or 10w30 diesel oil that is not synthetic i would be rather surprised…. You cant run t4 as you cant run 15w40 in these trucks…Why is that?

Good for you… this is the 19+ engines the thread is referring to so your non hydraulic lifter engine is irrelevantNot what my 18's manual says, unless it is below 0f degrees. Very rarely gets that cold where I live.

You got my interest, as I'm ordering a 22 CTD. So I just pulled down the 2022 owners manual from the Mopar website and it also does not specify synthetic for temps above 0f. It does recommend the 10-30 though, so that is good to know. And the Rotella T4 10-30 meets or exceeds the listed specs. I'll have to keep my eye out for a case of that. I can use up my 2 cases of 15-40 Rotella in the diesel pusher.Good for you… this is the 19+ engines the thread is referring to so your non hydraulic lifter engine is irrelevant
T4 10w30 must be a merican thing we dont even have a listing for it on the canadian shell site…You got my interest, as I'm ordering a 22 CTD.
