Got my new autometer oil pressure gauge installed, and im just wondering how much pressure i should have?

Right now im running 10w30 non synthetic and when cold, i get 50psi at idle, but after the motor is above 160degree's or so, i get 19/20psi at idle, and plenty when i rev it up.

Is 20psi at idle normal?

Probably. How many miles on the engine? That makes a considerable difference. General rule of thumb, you want at least 10psi per 1000RPM to be safe. More is fine. Synthetic actually acts like a thinner viscosity than the corresponding conventional oil, so it would be normal, especially in a higher mileage engine (100K+) for it to be a little lower than it would have with normal oil of the same weight. As long as you aren't getting blowby (does it smoke?) you should be fine with those numbers.

I'm using regular non-synthetic oil. Top end was rebuilt less than 1000km ago.. but the bottom end was not touched (previous owner).

Oops, non syth. I musta read your post too fast. I'd still say your fine, 20 is normal at idle.
