Delvac Extreme synthetic experience? Anyone completed OCI? Ty

[Krieg]

I've seen the VOA of Delvac Extreme Synthetic CK oil and another thread about this oil in the wild. But, wanted to see if anyone had completed an oil interval and what are their thoughts/experience?

The sample dated 4/30/2021 was Mobile Delvac Extreme 15-40 full synthetic. I was very happy with this oil. Of the 7300 miles on this sample, 2680 miles was towing my 10,000 pound travel trailer, including mountains. It tested as well if not better than any other 15W-40 Ive used.

The sample at 63908 was Rotella 6, 15W40, the sample at 58480 was Amsoil Signiture 15W40. Sample at 50054 was Valvoline Blue Conventional, 15W40.

Hope this helps

Thanks for reports just did first change on a 2021 6.7 Cummins 3500 with Amsoil ADN 10w30 at 4k mark been looking at many oils thanks gives me insight. Change was with OEM filters and engine dead silent after change keeping intervals short will run 5W40 in winter and might stick with 5w40 yearly.

The only difference I've noticed is that it maintains a higher oil pressure (1-2psi) at idle with temps 190-210 F vs others. Other than that, oil is oil lol

I’ve got it in my 18’ 6.7 CTD right now and it seemed to quieten it down but that’s with my ears and no audio meter. Just put 2500 miles on it pulling my 7-7.5k TT. Not really hot yet though. Pulled it pretty hard several times but hasn’t used any.

I recently put the 5W40 ESP in my 2020 and it's quieter than with the factory fill.

My truck doesn't rattle as much if there is Moly in the oil. Right now Im running 5W-40 Valvoline Blue extreme it has moly.
