I would step up to 10k, and see how that goes. I usually run traxxas 50k fluid, but I have no idea how that compares to other brand fluid. This is for vehicles that use motor brakes, as I like 4 wheel braking.

A heavier truck would need thicker fluid, but the 8 spider diff should have more gear contact, so it should lock harder than a 6 gear model on the same fluid. I would say to start with 50k and see how that does...
