What should my oil pressure be on a SR? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have 95SR20det Auto.I'm using an AutoMeter electronic oil pressure gauge 100psi max. When I start the engine and it's cold I get around 65 to 75psi on the gauge. As the car warms up my oil pressure decreases. I know this is normal. But after driving it drops to around 15psi at idle. My oil light on the dash never comes on or anything.I just think this is kind of low oil pressure. Under normal driving conditions or if you tap the gas pedal the oil pressure goes back up right away. My oil pan had a dent in it. That was corrected. I am using an oil filter relocation kit with a larger than stock (STP)filter. I have the oil pressure sending unit installed in the line between the filter and the engine.I'm using Mobil One 10-30 syn. oil. Could any of this be a problem? What should my oil pressure be at idle?

Pressure at idle once warm: ~1kg/cm2 ~ 15psi
3K RPM: 4kg/cm2 ~ 60 psi
