    Lets get a thread going here on which fluids everyone is using and where. This will make for a good list of fluids for future questions. I will start, lets try and keep this thread to a list of fluids and capacities only.

    Enigne Oil: Mobil Delvac 1, 10 Qts.
    Engine Coolant: Dexcool, recommend dealer flush and fill
    Front trans axle: Mobil Conventional 80W-90 Gear oil, 2 Qts.
    Transfer Case: Mobil 1 5W-30 engine oil, 3 Qts, (ATF Recommended by GM)
    ZF6 Manual Transmission: Mobil Fully Synthetic ATF, 6 Qts.
    Rear Axle: Mobil 1 Synthetic 75W-90 Gear oil, 3.5 Qts

    This should be a good starter for a reference. Remember, this should be what you use in YOUR truck to show different perspectives.
