    I believe that has to do with the viscosity (thickness) of the oil before it is warmed. A more “human” way of saying it is that the oil pressure may run a little high until things warm up ….. don’t worry about it …. but in normal operation it should not get over 95 PSI”.


    The yellow arc on the high side of the gauge is that 95 to 115 PSI range. I believe the yellow arc on the low side is for when the aircraft is sitting at idle. I’ve flown R-22’s, but not enough and not recently enough to remember much about them.
