What should be the oil pressure on different RPMS at hot engine motronic after an hour driving.

Min 7 psi at idle
Min 50 psi at running rpm.

And Greg:

Don't assume that the gauge is accurate. Get it checked independent of the Alfa gauges and sending unit.

Greg - I wouldn't worry too much about 40 psi. The engine's probably wearing or the oil pump getting weaker, but 40 psi is still good. You might try a 20w50 oil if not doing so already.
