So the CEN F450 I’m going to change the oil, bought 80w for it. It’s going to have a 5th wheel 3 axle holding 2 1/10 scale my rock crawler and desert rail. Think 80w should be good stiff enough

Hard to say man. I think you're going to have to experiment with it and see what works. It will probably be a tuning process because theres a lot of variables involved there.
