My tamiya grease is empty and I am about to start on my Tamiya Midnight pumpkin build. I have some hudy graphite grease that I use on my track racer (Xray XB2 and XB4)
Is this safe to use on the plastic differential gears?
I can't speak for the Midnight Pumpkin directly but I used to race a Tamiya Euro Truck in oval many years ago and never had any issues using white lithium grease, I can't imagine graphite being much different, this is what I use for all my cars:
