so iv been burning oil for a while now and was on the way home last night and was looking at my oil psi and at 90 mph it was below 50psi... at 1000rpm it was at 23psi??? its this nomal, i kow it has pleny of oil in it, i just filled it before i left. i thought i read that it is to be like 75 at highway speeds...

 

10psi for every 1000 RPM. speed dont mean anything.

 

so at 5k i should me pushing 50psi??
