OK? So, what is Metal Lube? And maybe more importantly... why am I writing this?

METAL LUBE is an anti-friction treatment based on an exclusive high-tech formulation, with the ability to drastically reduce friction by up to 95%

Why not contact the maker of the turntable you have and asked them if you can use the metal lube ?

If you want an oil designed for turntable like applications (not a gimmicky engine treatment), get some Mobil DTE Heavy/Medium, or Mobil Velocite 6.

If your table has a high torque motor, you can try Maryn Thixosyn grease. It can handle extremely high loads with absolutely zero wear.
