    Hey guy's heres the question. I own a Walker w/ 20 Kolher and want to start running Amsoil 10w30w in her. Also I want to run it in my truck also. Right now I'm running 5w30w Mobil oil in it. It's a 2.2 Vortec 4 cylinder. GM says to run 5w30, what I'd like to do is run the Amsoil 10w30w in the Walker and the truck, do you think it will hurt the truck to go to the heavier oil weight. It's a pain in the @@@ to keep so many different oil bottles on the work bench. Thanks for your advice.

    I'd be inclined to run what the manufacturer recommends in both the Walker AND your truck.

    That's only 2 different types of oil to keep track of anyway, I use 10w30 in my car and 15w40 in the truck & bike. No problem having 2 types of oil on the shelf.

    I would put the 10W-30 in both.
    And since you are using the premium Amsoil lubricant it would be even better.
    The auto mfgrs. will specify the 5w-30 to get a little lower viscosity so that their mpg figures will be a little better for the government to work with.
    Just my .02 worth....

    Definetely run the 10w30 in both,the concern is with cold oil flow,the amsoil 10w30 will flow better cold than conventional 5w30,so dont worry about it.

    I run 10w30 Mobil 1 in my mowers

    It's not that hard to have different oils Mowman :) As a matter of fact, you could roll down to a WalMart and buy some 5 quart jugs of Mobil 1 and not have to worry about all those little quart bottles :D

    See 30 or 40 oil post. Too much to retype.

    I does not matter what brand of oil you use. As long as it is the correct SAE.:)
