Glory,
Since you posted this on the IMC thread, I take it that you did not mean engine instrument. In VFR, I agree, the oil pressure gauge (the one we normally don't look at more than a minute after starting the engine) is the most critical.
I am also assuming that my wristwatch doesn't count as an instrument.
Byron, she's asked about the MOST important gauge, not the least important one.
I've had static failure. Having the GPS-moving map covers for a lot if you can call that an "instrument."
