What is the proper oil pressure for on 04 350Z with VQ35DE? At cold start up my oil pressure is around 80psi at idle. If I give it gas will go up to 100psi. If I get on it, will top out at 120+psi. Once it warms up, 35 psi idle. Hard driving wont top 90 psi. The dealer says this is fine. Anyone able to confirm this? I have two months left on my warrenty. If I should be concerned tell me now.

I just completed a stroker build on my 06 REVUP. I now am pegged over 120psi at 3k and at the end of the gauge above 3k. I have all new internals including BC 88mm crank, JE 11.0.1 pistons JWT S7 cams & springs, Manley +1mm valves a new revup oil pump etc.

On initial start up and the second oil change I used 10-30 Valvoline dyno. Because of the high pressure I used 10-20 Catsrol GTX hoping to bring the pressure down with no change.

Should I be concerned?
