Moly 5th Wheel Lube is a semi-synthetic, diluent-type heavy duty, extreme pressure spray lubricant recommended for the lubrication of fifth wheels. Moly 5th Wheel Lube is compounded from a unique blend of select high viscosity index paraffin base oils and synthetic base fluids. These base fluids are further compounded to provide Moly 5th Wheel Lube with superior adhesive film forming characteristics which allows Moly 5th Wheel Lube to resist “squeeze out” and cling tenaciously to plates.
