ITSpecialist Posted March 20, 2008 Share Posted March 20, 2008 Quick question about the Oil Pressure Gauge, not being up on mechanics can someone tell me how this gauge works and what to expect from the read outs that it's giving me? e.g good readings matching engine performance etc...

The oil pressure gauge shows the pressure created in the engine by the oil pump. It is linked to a 'sender' which is what actually measures the pressure. I don't know exactly what form the sender has on the Z but it will most likely be a spring-loaded diaphragm. On start-up until the car is warm the pressure will read between half-way and three-quarters on the gauge, I forget what this equates to exactly but I think between 60 and 90psi. When warm the gauge normally reads at the first, quarter-mark which is about 30psi IIRC. The Nissan test for low oil pressure defines the threshold below which to be concerned as 14psi again IIRC.
