Oil pressure about 20 and 17


Recommended Posts

Thanks for the feedback.

 

As my understanding this table is showing the oil temperature on the left side and on the right side is the viscosity for each .

 

as you see in 20w @120C the V =6 

 

how much this will be on the oil pressure, as these are our conditions.

Nothing you can measure. Compare your cold and hot idle pressure. That is the difference 60 to 70 cSt makes. This is only a few centistokes. I've run 0w20 to 10W30 in mine and never notice any hot pressure changes.

Does this all look ok? Back in October engine blew! Still owe on my Yukon. And no warranty. Fast forward, new engine, new shocks, new starter. Took my car to GM because I had a PO711 code and they changed the harness. Once I got my car back it went into shock. Engine light came on and the sensors were going crazy along with my fans running. Mechanic reset computer. It’s driven 500 more miles with nothing else. Should I be worried?
