Oil pressure gauge
 

How do i fix my oil pressure gauge when the car is off the needle falls really far down the gauge??

The needle should drop down when the car is off... there is no oil pressure.

How far down?

Like at far down? ^^ If so, either someone messed with the needle on the gauge or the gauge failed like mine has.

Carzy Driver- yea its like yours it kinda works when the car is on but i think its pretty much fucked, were do i find a new gauge i heard the Mazda stock on suck anyway.

jjcobm- yea.....no shit

look into the autometer ES series of gauges. you should be able to get a mechanical oil psi gauge, and a cup, or mounting bracket for $60 or so shipped form jegs.com, or summit.

autometer makes great quality, and reliable gauges. the ES series if gauges match the FC interior (black face, red numbers/needle, and light up red at night.

I simply replaced mine with a Autometer gauge. Cost was about $50 total for the gauge and Re-Speed adapter. But if you can replace the stock gauge by taking your cluster apart and replace it if a working gauge pack, or just readjust the needle on the gauge since you say it still works. Either way will take about the same amount of time to complete.
