Metal Conditioner Squared or MC² is an antifriction metal conditioner and works differently than regular additives. It utilizes nanotechnology to bond to metal and fill in microscopic pits and grooves making the metal smooth. In doing this, MC² lowers the coefficient of friction, lowers operating temperatures, increases efficiency and even increases the surface hardness of the metal. MC² is compatible with lubricants such as petroleum and synthetic oils, greases, automatic transmission fluids, hydraulic fluids, and can also be used in air conditioning systems.
