Oil Pressure

[jdf]

What is the normal oil pressure for a 4.5 Cerbera?

[AndyTather]

When my 4.5 starts it goes up to 50-60psi or more and then as the engine gets warmer it lowers to about 30-35psi at idle.

I think all cerbera's are a little different though.

At this time of year when the car is running cooler I get the following on 15w-50 Mobil 1
53 to 55 psi @ 3000 rpm
42 to 45 psi @ 2000 rpm
33 psi @ 850 rpm idle
Reckon on 3 to 5 psi less if you are on 0w-40.
This I believe are true figures as I had the gauge checked against a reference standard about 9 months ago and it was spot on across the whole range from 0 to 60 psi (must be the only one!!)
