    i run 10w30 in everything except smokers


    put new valve stem seals in

    if it still smokes then its time to take it apart and do guides or rings


    good luck

    40w or 50w are heavier. i usually put 10-40 in my dd it has 200,000 on it. 10-40 or even 50w if it's warm out should be ok

    as crazyhole pointed out, 50w is a common heavy oil...

    if i'm looking to run something on the thick side, i run 20-50...

    Put a can of "restore" in it. Autozone has it, it comes in a silver and black can. It will help lessen/stop the smoking.

    Fix It!!..

    Nothing will slow oil consumption better than replacing the valve stem seals.(you might need guides too,or to have them knurled!)...
    --you can put off re-ringing an engine by using heavier oil,but the valve stems will still suck enough oil past them to smoke and burn some, no matter how thick it is..and heavy oil flows slowly on cold start ups,and can cause more harm that way...I'd use 20W-50 ,if that does not help,then its time to fix the cause,and not treat the symptoms..

    Of all the engine additives,I'd avoid using "Restore"..its like aluminum paint,consists of lead,silver,and copper in powder form..not something I'd think was good to pour in an engine!..I've seen many blow up shortly after ading it!..I'd trust a petroleum based additive like Lucas or STP long before I put powdered metal in my motor!..try a "High Mileage" motor oil,they are specially formulated to soften up old dry hard seals in older motors,and have higher flash points,so less will be lost to blow by and seal leaks..--all of my Chevy motors had the "chevy puff" when you start them..I think its GOOD to have a little oil upstairs when it first starts!..:crazy:
