Im thinking of fitting a buzzer that will go off when i have low oil pressure. I have read on here that the standard oil pressure switch is next to useless so what would be the best pressure to activate the oil light and a buzzer?

Demon tweeks have this range of 15-30 psi what one would be best???

Standard switch is 2 psi. Most scoobs idle at around 30 psi or slightly more or possibly less depending on engine condition. 15 psi seems the right one or you might get alarms every time at idle. Better but far more expensive is to fit Defi gauge which will allow you to set alarm just below whatever you get at idle.

 

ill wait till the engine is back in the car then and see what it does on tickover
