I am 100% in agreeance with this. This is why I dont believe in "upgrading" to a Mellling because I dont see it as any better than stock. I believe the oil pumps that fail, were installed incorrectly, or trying to run oil that they were not designed to move. Sure, just like any mechanical part, they break. But a Melling can break too. I just dont see it as insurance if everything was put back together per spec.

Guys you can run a thicker oil without damage to the pump. That's not an issue.

Hmm....Ive just always mentally been against that because the oil the factory puts in, is what the mechanical parts are setup to run. To run a 50w oil, youre almost doubling the viscosity of what that part is designed to run. Obviously with a built engine, stock specs go out the window, and the builder should determine the oil, and the oil pump needed. A Melling is crucial for built engines or stock engines that are road raced and sustain high rpms for minutes at a time. I would by all means listen to Zeke over me OP. That is just the way Im thinking of the subject, not necessarily a fact.

This is what i found: The thick oil like 20W50 can not flow through suck a tight space and engine does not get the oil it needs In time. Using 20W50 In an engine with modern tolerances will Inadequately lubricate the Babbit bearings on the crank and camshaft and the rings and valve stems .. pretty much everything, In fact. The engine builder is telling me to use 20W50 I think I'll bring him 10W40 instead! |

I asked Andy at ADM about using a melling on my 417 and he said he always uses the stock GM pump on all his builds. He said it basically comes down to who installed the pump and cam or whatever build was going on at the time so he put a factory GM pump back on mine and I will be running 15w50 mobil1 in my new build.
