Defi Gauges problem

[AyoDaesu]

So my oil pressure gauge started beeping.
From start up is fine, its only when the engine gets hot then the pressure drops.
Oil is fine .. could it be something with the wiring or censor itself?
A leak also came to mind but I am not overheating or leaking anywhere.
Any suggestions?

Thanks

At what PSI is the gauge warning you?
Oil pressure drops as the temps rise, your oil might be getting too thin.
You could try running a thicker oil.

try a thicker oil. or your sensor is messed up.
i would stop running synth, and try a thicker conventional.
