Normal oil pressure at idle would be about 30 psi. Minimum would be about 10.
Some vehicles` oil pressure will do this when at an idle. This is normal, if the oil pressure does not get higher when at higher rpms then something may be wrong.
It is normal for the oil pressure to drop when the engine is warmed up and at an idle.
Normal is 30 at idle. 50+ at 3000 rpm. Minimum is 12 at idle.
Normal is 30 psi. Minimum is 7 psi.
Normal idle oil pressure would be around 30 psi. Minimum pressure should be about 10 psi.
Around 40
This old? 20-60 psi at idle
Probably 5 psi to 60 psi.
Hot at an idle, 15-20 psi.
Don't know what vehicle and or engine you have but some idle with normal oil pressure of 8 psi or less.
Bad oil pressure sensor. Simple unscrew the old one from the oil filter housing and screw the new one in.
