Yes, I realize this. I had the auction mechanic put a manual guage on it and aslo he printed out the service bulletin about the guage. The manual guage read 0 psi.Big_D said:FROM THE FAQ
Why Does The Oil Pressure Read Low At Idle?
For 1991 cars serial number 3162 or lower, see Service Bulletin 91-008
[A/H] The specification at the engine oil pump is 0.7 kg/cm (the dash gauge reading) or (10 psi) at idle. The + - value of the gauge is 0.5 So, given all the little electrons and the hot oil molecules line up on the soft side your gauge could read very close 0 at idle. Unless the light comes on (see your owners manual) I wouldn't worry about it. You could always install a gauge and check it at the oil pump. We haven't had a problem with oil pressure in unmodified cars.
My reads low at idle as well
