    What motor oil do you run in your Truck?

    Well I think it's obvious what I use. The proven best, AMSOIL.

    I use Royal Purple and have for the last year. I've gotten about the same service as from Mobil 1 and may at some time switch back, depending on expenses.

    I used Amsoil in my last Silverado ('89 R-30), but I am using Mobil1 in my current truck ('08 1500) and in my RVs. I would probably still be using Amsoil if there was a convenient place for me to get it. I use Valvoline Synthetic in my Samurai, but I'll probably switch over to Mobil1 in that too. Whatever the dealer puts in the wife's car it what it gets.

    i voted Mobil 1, but I actually use Mobil 5000 conventional oil; I'm in high school and I'm strapped for cash. It's a nice medium between synthetic and 3000 mile conventional.

    Castrol GTX - have used it for years. Good enough for John Force (I'll let his penchant for Fords pass), good enough for me!

    I first used Mobile 1 in 1980 and with the old corkgasket system could not keep it in engine but I immediately recognized the superior qualities of synthetic lubricants as to how easy I could crank off a 390 Ford at -10°F.
    Then I guess it was 86 I started running it in one vehicle at that time, then another and now I have put about 675K on several vehicles with it running it 15K or more between changes. Have not had the first bit of engine problems since that time.
    We now have three pieces of rolling stock with a combined mileage of 448K. I also have it in a International 140 tractor, Honda generator, Honda lawnmower, weed trimmer and use it to lube my guns and clean the gas systems on the semi autos.
    I also use it in my electric motors that have lube ports. I started this in circa 1991 when I talked with a electric motor rebuild facility in Columbus, Ga. They told me to run Mobile 1 as they put it in all their rebuilt motors and had never had one returned for failure with Mobile 1 run therein.

    I have about 80 quarts of it laid in. I run 10W30 even though the new engines say 5W, the manuals also say 10W is fine so it will continue to run it.

    Should I get another vehicle and the manual calls for 5W only, then I guess I will switch but I suspect that may be a litte or long while now and whatever it is I can assure everyone the next vehicle I purchase will not have been touched by a UAW worker.
