How is she doing after the sand pit incident would be a true test of the cerma.
Not realy sure it actualy would. The down sides are the extra strain on the pumps drive chain will stretch it faster and the additional distance the relief has to travel to maintain the oil pressure should weaken it's spring in time. Maybe after things get to the point of needing replacement and it starts using oil go to a bit heavier oil but... IMO...if you are having engine cooling problems, look into an oil cooler and look for coolant systems problems.That's what I thought I've heard ppl say 20/50 because it would help keep them cooler
Thats what I run in my Cummins lol. 10w-40 in the brutes....Castrol. Ran 10w-40 Royal Purple for a long time in my 08, but since the rebuild I havnt bothered to swap it back to synthetic. Running BRP Summer Blend (20w-50) in both of the hams.I still like running rotella 15-40 in mine.
X2 done it many times no problems.Just go straight to synthetic. The whole Dino oil to semi-syn to full-syn is an old wives tail leftover from the 70's.
Back then the synthetic oil they had wasn't compatible with Dino oil, nowadays it is. And besides when you do an oil change you'll be leaving behind like an ounce or two of old oil, not enough to matter.
