2005 Silverado WT 4.8. Recently purchased and restoring.


209K, I am at 40 PSI after additive and changing the oil with high mileage conventional oil. It was  lower.


Appreciate the information, but just another "thing" i should look at.


40 PSI is in the middle of the gauge and what I was taught, middle is good.


I have read about 60 PSI?


Would anyone know what the correct oil pressure should be ?






Minimum oil pressure specs are as follow:


6 psi at 1,000 engine RPM

18 psi at 2,000 engine RPM

24 psi at 4,000 engine RPM
