I would like to see analysis for fuel dilution on a deleted 6.7. Same year head to head of course to see what, if any differences the regens actually make.

I'm still getting used to the PowerStroke I guess, I never (nor did forum folks) have worries about oil dilution on my Duramax no matter how much it idled or drove slow and no oil analysis ever made me think otherwise. What's the difference?

GM has used the 9th injector since LMM or LML engine, at least 2011. Ford just saw the light in 2023, until then they relied on the exhaust stroke method like Cummins still does for the ISB in the dodges.

Me too! It sounds like Regen is not the issue if 9th injector trucks still have fuel in the oil.

I haven't run across any comments from 23+ owners concerned about fuel in the oil based on their test results. Would be an interesting comparison though.
