RE: stock fuel pressure
Oil pressure varies depending on many factors, like oil viscosity, engine (and oil) operating temperature, engine speed, etc. Generally speaking you should have 75psi or so at a cold idle (the oil is thicker) and around 30psi at a hot idle. While cruising (3k RPM) at normal operating temperature you should have around 50psi-60psi.

RE: stock fuel pressure
hmmm well thats odd my car generally runs at like 60-65psi at idle when cold and when its warmed up it idles between like 20-27 psi.... is this bad? under cruising my oil pressure is usually around 45-50 @ 1.5-2k RPM, and it goes to 50+ for anything above 2k RPM i also use 5w-30 right now but generally once winter comes around i use 10w-30 just for a better cold start....
