As we are using a motorbike engine, the oil pressure is a lot lower (17-26 psi) than on a car (upto 120psi on guage) and therefore the oil pressure gauge will only be registering on a on a small percentage of the range. The gauge is electronic and picks up from a sensor as usual. I am not botherd if the gauge reads incorrectly e.g. 10-75 psi, but would just like the operating range to be a lot larger so that fluctuations will be easily seen. Anyone got any ideas?
