Re: Oil gauge wonky! Works/doesn't work?
Short answer yes, unless your engine sounds different when it "loses" pressure due to lack of lubrication.
BTW its not a sending unit, its a switch. As soon as pressure passes a threshold the switch closes and cause your needle to go straight to the middle. A real gauge will actually move with the changes in RPM.
