Read a paper online from Bentley motors. The outcome was that lubricant was not a good idea on wheel studs. My empirical experience over 45 years motoring whereby I always used CopperSlip has so far never involved loss of a wheel or further torquing between services. 
That said I don’t doubt the science regarding clean / dry surfaces being theoretically better.
