Stock Oil Pressure gauge reliable?

(Sorry, I'm not goot at English)



Hi Guys. I have 04 RX-8 automatic.



I have a question for Stock Oil Pressure Gauge.



Needle is always on Middle. Just little more "High" level. (Actually, 2 point and half)



I know this needle position is normal and fine.



But, I really want to know is Accurate Pressure Number (As You know, Needle doesn't show number)



How can I get Oil Pressure Number(Figure) ???



I have OBD-2 Bluetooth Scanner(PLX KiWi2 Bluetooth) and Torque Pro APP.

But, "Torque Pro APP" doesn't show "Oil Pressure Gauge" :-(



I'm worry about Stock Oil Pressure Gauge's reliablity.

If Stock Gauge faulty, It means damage to APEX Seal (Because, can't Lubricate)



Anyone know figure out Oil Pressure Number?
