I made a viscosity test like 2-3 month ago and i figured that the viscisity of lubix is between 30 and 50k so a ~40k is a good estimate knowing that lubix is 40k +- 10k (30k-50k)
But it is not lubix because lubix claim that the lube is not toxic and on the traxxas bag say that it is a carcirogenic substant.
But if ur not solving the cube with ur mouth or under water there is no problem just dont eat it =P
