Oil Pressure Gauge
 

I have one..

but aint got a clue what it does..??

iirc measures the oil pressure Sam :)

Normal it's just there to worry you and just when you think everything is fine it will droop to zero...

LOL

DunxC

P.S. If your oil gets way to hot, your oil pressure will wilt, and eventually your engine will die. Happy soul aren't I ?
