So there is no need to worry about the engine running out of oil pressure? It sometimes reads right at the very lowest possible on the oil pressure gauge. I didn't know if that meant there was 0 psi or if it is just enough to lubricate while idling?

I find myself bringing the engine up to about a 1000-1100 RPM idle just to bring it up and make myself feel better. I don't need to do that?
