not sure how regen would or could cause fuel dilution, at least in my truck. The regen fuel injection is downstream in the EXHAUST manifold with a "9th" injector in the exhaust pipe just ahead of the soot trap. Tell me how that would cause fuel dilution in the oil?? During regen the direct injection into each cylinder is the same as always.
And Blackstone oil analysis after 10K miles shows zero fuel dilution in the oil as well which validates how well they system works without fuel dilution.
I was referring to my diesel engine, not your CP4 Duramax.
