    T0-4 oil, not sure what that one is. I use the 15W-40 in the engine..I am in australia so not sure if we have T0-4 but can find out if we have a alternative. Thanks for your reply.

    TO-4 is a Caterpillar Spec. Any good oil supplier should carry a TO-4 oil. If all else fails you can buy Cat TDTO from Westrac. Viscosity for a transmission would be SAE30.

    It's a B model loader. Any 30 wt. engine oil will work.

    Only if its a TO-2 spec motor oil. Bob
