Oil pressure with a cold start

Post by **9240sx** » Mon Jan 14, 2008 12:12 pm

I was just wondering what kind of oil pressure you all were getting at a cold start..Iv got an autometer gauge and im getting 85psi..Does that sound right?

What is the weight of your oil.The difference in oil weight is a factor.

Good'ol 10-30

Yea that pressure sounds right you are good.

^yeah I run about 75-80 psi cold. I use autometer gauges too.

whats normale hot engine oil pressure?? mine only runs like 40psi idle to 50 maybe 60..with 10w30

what is your idle speed set at, Ive run 10W30, 10W40, and 15W50 and my running temp idle oil pressure is always 20 psi, 40 psi seems really high for idle. 80 psi is normal for cold starts.

i've got 5w 30 royal purpe in mine with autometer gauges and mines 80 during cold start and between 40 and 60 while driving and 20 at idle..... its less than 20 at idle if i have been driving it hard.

5W30 is a little thin for a turbo engine, I would suggest switching to a 10W30 or 10W40, they have a higher thermal capacity that will hold up better under the extreme heat caused by the turbocharger. I pulled this from the SR20DET FSM, it does not recomend 5W30 for temps above 59 F.

^yeah, I run 10w-30 now (colder months) and ran 10w-40 in the summer since it is hot, humid GA

the gauge was free. its in bar tho. one to seven bar.. electric. myn goes to seven stays there til motor warms then down to one bar.. does anyones pressure go up with rpm? sometimes pressure drops off and fluctuates...>?

You may be low on oil or having oil-pickup (read: starvation) issues.

Yes oil pressure increases and decreases with engine RPM.But oil pressure should not drop at random. If it is you have a problem

I don't understand your post in relation to the OP, but do you guys realize that this thread is 2 years old? LOL

EDIT: While the FSM (S14 SR20) has no cold PSI rating, it does state with the engine at normal operating temp, under no load, it should run more than 11 PSI at idle and b/t 46-57 PSI at 3,200 RPM.
