That's pretty normal after the truck is warmed up. 50 psig is plenty for idle. The old rule of thumb is 10 psig/1000 rpm. That's kinda low for my tastes but we have it beat by a mile.iahemiram said:Jimmy...
Is your oil pressure still fluctuating? I noticed mine at 75 and 50 within a matter of minutes. Whenever the truck idles it drops to 50, but when on the move, it is at 75...
