What would good oil pressure be?

[drvon]

So I just installed a new oil pressure gauge, and was wondering what would a good reading be. I have a 4L SOHC, and once warm it seems to be around 30 psi at idle and around 55 psi when cruising around 65 km\h.

That's what it should be! Your good

That's plenty. The old rule is that you need 10psi per 1000rpm. You might even switch to a thinner oil.
