    Use a thicker oil like 10W-40

    Pull the plugs and tell us what you see. Are the electrodes coated with deposits? Pics???

    Either leaking or burning. The laws of physics say so.

    It's your engine oil seal making way.Time to do some top overhaul. Do check with the mechanic

    Today I read a GM bulletin that said a possible cause of oil burning is the PCV valve an it should be replaced with a later model such as 2003 without the check ball,several owners said this cured their problem,I ordered one today,will post when I get results,Paul

    120k miles and a quart every 500. Doesn't sound like a crisis to me.

    The dark green wire between the relay and the horns.
