My 632 CID pump gas engine has a Melling standard pressure/high volume oil pump. Even when the engine reaches full operating temperature, the oil pressure is at about 32 PSI during idle, and climbs to 79-80 PSI by 2,500 RPM and stays there until the throttle is let off. This is with 10/40W oil. Is that a bad thing? I welcome anyone to comment, but I especially hope to hear from you guys who are professional engine builders.
