Just wanted to see if anyone has seen this: Oil pressure gauge showing about ~10 psi less than the 'gauge in the scope(bar)window' readout. 2017 991.2 c2. Really new to 911 so my ignorance may show quickly. Which reading would you trust? Can they calibrated?

I had the same question with the first 911 that had digital display. The gauge is reading bars & the display is psi. Round numbers; 1 bar = 14.7 psi. They “are” calibrated! So rolling along at 30 psi, the gauge will read just above 2.

I’m surprised. Using bar units on the analog oil pressure and Fahrenheit on the temps! Of course you’re right I checked by switching units under settings. I guess I just couldn’t believe engineers would mix gauges. Probably a US import change. Thanks for clearing that up
