Me too! 

I have been using 100K weight Traxxas diff lube (silicone based) as of yesterday (3 fills from 1000psi to 3000psi 490CC) the load meter has not gone above 20. I tried it with just normal silicone oil when i first got it and the meter would hit 26-27. i dont know how accurate the meter is but hopefully it is an improvement. I may try the 500K weight for poops and giggles.
