Oil pressure gauge

[01Tahoe]

Oil pressure gauge can anyone tell me if their gauge goes to zero when you turn off the engine(after warm up)?? If it does, how long does it take to go to zero?? This is for a 01 Tahoe LS.

Thanks,
Mike

it's most just the oil pressure gauge that's faulty. if you're under 80k miles, the dealer will fix it for free.
