What is a normal reading for the oil gauge?
Gauges that register in PSI, usually range from 0 to 100 and the normal zone on these is between 20 and 80 PSI. The oil pressure gauge measures the resistance to the oil being pumped through the engine by the motor’s oil pump. The temperature of the oil, the type of oil and it’s viscosity all affect that resistance.
