engine oil pressure requirement

Recommended Posts

As long as oil pressure is 10 or above at idle oil pressure is good.  I have a 454 and used to run 20-50 valvoline vr-1 all the time. Thats how it used to be old school thought and that is what my engine builder said to use. I have a roller cam and roller lifters I bought through Chris Straub  - https://straubtechnologies.com and they says  10-30 to 10-40 driven racing oil. Some say it all depends on bearing clearances tight or loose. But now i run the 10-30 driven oil. I have 20 15 to 20 lbs at idle and goes up from there when driving.  Im definitely no expert hopefully someone else will chime in.

hi, i also have a  454 stock, and used to use 20w 50, now use straight 30 w  I was told the 50 breaks down first then 40 then 30 and so on ,i don't drive very much but will change oil often.
