whats your avg oil pressure?

at idle after just started

and warmed up at idle

[sman]

Mine used to be about 60 regardless, a pinch higher when cold.

wow
somthing must be wrong with my car
its at about 60 when first started
and goes to 30ish when its warm

in the 200* area

Could just be tired, could also be the oil and filter combo you have. What are you running for oil and a filter? Have you tried changing the oil and seeing if that helps. BTW, 30psi is quite acceptable at idle. On a GENERAL basis, you need roughly 10 pounds of oil pressure per 1000rpms.

its some conevtional 10w30 castrol
i heard not to use syn on break in

and a fram sure grip filter

[sman]

I run GC 0w30 in the new motor, but ran any general 10w30 in my v6 and had no issues. But that fram filter scares me, some people get lucky, but others, not so much. Youll never see one on any of my vehicles.

whats wrong with them?

what should i use opposed to it

[sman]

They have a tendency to crush themselves.

Pretty much anything is better than fram oil filters. Mobile 1, pureolater premium plus, and napa gold are the best. IIRC k&n isnt to bad either.

[JoeliusZ28]

mine also seems to hold a pretty constant 55-65 psi no matter what and a little more cold.

[jderry]

yeah theres no reason for mine to go down i dont think

i have a brand new oil pump and all mains and rod bearings are new


sould i try running 10w40?

[sman]

I dont see why. Like I said, 30 is fine at idle, what is it while crusing and getting on the gas?

just crusing at say 1800 rpm its only like 40psi getting on it itll get to 65

but i looked somewhere online and it said it should be at 60 at 2000 rpm

It might just be a bad oil pressure switch. Hook a manual gauge up to it if you can get your hands on one and see if it reads the same.

[Kwazrollinz28]

when i had mine it idled just under the half way mark and really never moved when i reved it up i used 10w40 with a K&N filter same as i do now with my Z

[SSTODD]

Thicker oil is not the answer, stay 10-30 and change the filter to a napa gold or other. NO FRAMS!
