Not for your average gas engine. My 4.6 Triton had a hard time loading the lifters back up. Drained and refilled with Motorcraft 5/30.

It's all I use

I drive a 2017 RAM 3500 DRW HO with Aisin. I switched from the Delo 15W40 to this oil. I live in WA state, we have mild temps and the Delo isn't Cummins endorsed anymore. This is Full Synthetic, Cummins endorsed oil. I run this with a RP filter. The motor seems to like it alright. Smooth idle and good oil pressure (based on the truck computer). It will be even more beneficial when that EGR is gone.

IMO the best product out there! Although Cummins recommends 15k mile oil changes, (why?). I change at 7500 miles. No oil pressure changes/problems ever noted. Got my son-in-law to switch in his Chevy, now he’s sold on it.
