Ok, Silly question, What is "normal" oil pressure, when warm at idle and at speed?





Thanks


Keith

Typical oil pressure on my 03 with 5w-40 synthetic oil is as follows:

Cold
Idle: 60-65 psi, 1500-2000 rpm: 90-95 psi

Warm
Idle: 28-30 psi, 2000 rpm: 60-65 psi

My pressure figures are exactly the same using dino Rotella T 15W40

My oil pressure is pretty much the same with Amsoil 5W-30 synthetic and dual remote full flow/ bypass oilfilter setup.

MINE IS THE SAME AS ABOVE.....DONT LOOK VERY NICE WHEN HOT RUNNING 28 PSI IN A DIESEL....KINDA MAKES YA WONDER WHAT ITS GONNA RUN WHEN ITS GOT 300K ON IT !
