View Full Version : Oil pressure at idle

We got a HO 3.1 GAGT and the oil pressure should be 15psi at idle or 1100 rpm.The gauge shows right above the red at idle and while driving shows about midway to 40psi.I have not put a manual guage on it yet,I was hoping that someone cost post up a couple of vids of there car at idle and driving to just verify.

my car idles with between 25 and 27 psi of oil pressure and under normal driving it doesnt get past about 45. Ive seen it as high as 62 on a WOT run.

27 views and 1 person has got input.Silvergtjrod do you have an aftermarket guage or are you going by the factory.What weight oil are you running.

i would recheck the oil pressure with a guage and for the most part oil pressure should be 15 psi at 1000 rpm.... idle is at about 650-700 i would also try doing an oil flush somtimes oil passages can get plugged up and cause oil not to flow evenly.....just a thought

25-27 at idle seems about right, once it warms up will drop as low as 20, but I never get much over 32psi during normal driving conditions. On WOT, I haven't really payed attention.
