I still have my 1984 Renault Fuego, it has an oil pressure gauge that reads in Bars, but does not give any unit on the gauge, just says 1 thru 6. It's in the manual that you find the oil pressure is supposed to be no less than 2 bars at 2000 RPM when the coolant is around 80 C. I never heard of anyone in the US having a problem with this. The other nice thing about this gauge was that it actually went up and down as the RPM increased or the oil got hotter, etc. The water temperature gauge was so accurate, you could see it move slightly as the thermostat opened and closed.
