Under normal conditions I don't think fuel dilution would be a consideration.

I was trying to remember the idle oil pressure on the old Cammer's or 855. Seem to remember 30'ish. Not like 50 or 60 on a hot Cat.
855 had "new and improved " design high pressure external oil lines to the cooler, this I remember because I had one of the first out and lost a $1.80 o ring. From a standing stop to 60 mph it emptied the crankcase down the right side of the truck.
