Oil pressure gauge
My 2010 Cadillac CTS 4 with the 3.6 liter has a fluctuating oil pressure gauge. It bounces from 0 to 100 and vice cersa, and never settles in the middle. No warning lights ever come on and all other gauges operate as they should. The car is running fine. My question is, does this sound like the sending unit and am I safe to drive until I can get it next week?
