    I'm assuming to the oil gauge. Went to mechanic today and he told me that based on his experienced with S10 pickups it could be this faulty unit sending an inaccurate message to the oil gauge. Do you have any idea what they are talking about? I figured it must be a sensor or relay unit i'm presumed

    You need to find a tech that will perform a oil pressure test with a direct feed oil pressure tester gauge.
