    Ok its time to see what everone is using to PROTECT their engine.

    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.
