Which weight of differential oil is better? 30k or 50k? Or is there another wt that is even better than these two?
Because I know that on the "Lubix viscosity found" thread, 30k is the recommended wt, but 50k is a good alternative....But I also heard that if someone wanted to buy a lubricant that had the closest viscosity to Lubix, they should get 50k. And Lubix being a very good lubricant, I would assume that 50k should (also) be a very good choice. Or maybe I'm just confused.
