I know this may be in the manual but I'm too lazy to go outside and get it.

What is the correct oil pressure for the Z. After it warms up, I read about 15psi at idle and about 60 cruising at 80mph. That idle pressure seems low to me. But the dipstick (after several tries to get it right, that thing sucks) reads right.

 

oil pressure changes according to your speed, (at high speed the pressure increases)

 

oh and also the temp. of the weather plays a major role on that

 

I had the same concerm when I first got my Z. Oil pressure at idle seemed low (10 - 15 lbs). My Ls1 held 35 - 40 at idle.
