Q\'s about autometer oil psi gauge readings

What are the average readings? Ive been getting conflicting answers.

PSI at idle? under acceleration?

Im using a mechanical gauge and under cold engine temps, sometimes the gauge reads way past 100psi under acceleration

Usually Im getting 60psi at idle and around 80psi cruising. One of my buddies told me to prime the tubing of any air and I did that. Now the needle seems more responsive, but readings are the same.

MODS: please do not move this topic to interior.

Not that this will really help but I get the same thing. Does yours sit at 80ish psi and then slowly work its way back down to 60? Lately mine has been as low as 40psi after an autoX run.

Do I trust the gauge no, will I sell it for a electrical gauge yes.

Where do you install the sender??? I have an electric Auto Meter Oil Pressure guage laying around from my old car, I just can't find the stock sending unit....where is it?
BTW, according to my repair manual oil pressure readings should be at 19-36 psi at idle (800-850 rpm) on a normal operating temp and 53-81 psi at 4000 rpm.

yea sometimes it will do that

Mine is a Mechanical Pro Comp Ultra lite.

ON a cold start, under acceleration the needle pegs at 100 if i get on it.

at temp, it idles at 25-30 and at 3-3.5k rpm it hovers around 70psi.

The stock oil pressure sender is just a pressure switch, take it out, replace it with a "T" fitting (I think its AN hardware) and put the sender back on one and the autometer coupling on the other end. VIOLA!
