Pretty sure viscosity is the most important factor but I am not an expert then it come to tribology. There might be non newtonian lubricants, would guess higher viscosity at lower shear rate would be good as if I got it correct higher viscosity is better at lower speed while lower viscosity is better at higher speed.
