Oil pressure gauge

5

Asked by Aug 21, 2014 at 06:16 PM about the 2010 Cadillac CTS 3.6L Premium AWD

Question type: Maintenance & Repair

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?

I would not run the motor until you can confirm that there is continuous oil flow/pressure to the motor.

My 2012 CTS LS is doing this exact same... took it to a dealer, they said they didn't see anything and we drove off without any maintenance performed. Going to take a video of the 100 reading and show them, it rarely goes to 0 now, but 100 quite often.
