    GMC 3500 duramax. The oil gauge drops to 0!! Sometimes it pops back up, other times it stays there for a while the goes back to normal. I've tried 4 GM dealers -they can't figure it out. Does anyone have any ideas?

    Is the pressure actually dropping?

    I'd say it's most likely just the stepper motor for the gauge going out.... But I'd stick a mechanical gauge on it to double check...
