At cold start up oil pressure fluctuates from 20-60psi. Once warm (approx 180 deg Fahrenheit) pressure is consistent with rpm increase. At idle hot is 60psi.

Getting older and get tired working the wheel so thought I'd try something a little different. <br clear="none">My concern is the cold oil psi fluctuation and the higher than previous high rev psi.<br clear="none"><br clear="none">Thoughts please.
