    Unhappy Oil light comes on in an 98 Deville N*.

    Once in a great while my oil light comes on at idle. It will turn off as soon as i apply the throttle. I know what kind of damage an engine goes through with no oil pressure. Please give me some advice on this senario. Thanx.

    Red face Re: Oil light comes on in an 98 Deville N*.

    Had (have) the same problem occasionally. If the QUANTITY of oil is sufficient, and it's a good QUALITY, it's probably the pressure sending unit. I have a 99 Deville, and soon after I got it the LOW OIL PRESSURE-STOP ENGINE warning came on one hot afternoon after about five or six miles of stop and go traffic jam. Stopped, checked level (after a few minutes) and it was fine. Revs made light and chime go out.

    Checked with Dealer - bad switch. Replace under warranty.

    The switch is right next to the oil filter, and it's entirely possible, if not plausible, that a ham-handed filter replacement can knock it out of whack.

    Check the oil level about once a week, and keep it in the hash-marks. Have the dealer check the switch next time you're there.

    Since you appear to have joined recently, the best thing you can do is search for and read every post made by Our Leader and Supreme God-like Being Who Can Do No Wrong, bbob the Great.

    Rumor has BBob was born inside a N* oil pan and took 10w-30 with his Gerber and Similac..

    Seriously, though just go back and browse the threads in the N* Tech Discussion forum. Fount of Knowledge and all that....
