Lubricating compositions and method of using same

A lubricating composition comprising a major amount of a lubricant and a minor amount of a salt of tetrathiocarbonic acid of the form M.sub.2 (CS.sub.4)y wherein M is ammonium or a metal and y is the valence of M.

A lubricating composition comprising a major amount of a lubricant and a minor amount of the reaction product of a mixture of a metal alkoxide, hydrogen sulfide, sulfur and carbon disulfide with said reaction product forming as a result of the reaction of equal moles of sulfur, carbon disulfide and hydrogen sulfide with 2 moles of the alkoxide moiety.

A lubricating composition comprised of a major amount of a lubricant and a minor amount of a tetrathiocarbonate complex of the form:

• (CI).sub.x (M.sub.z (CS.sub.4).sub.y)
• wherein M is a cationic, complex-forming metal, z is the number of atoms of M in the complex, y is the number of tetathiocarbonate groups in the complex, CI is a neutralizing counter ion, and x is the number of counter ions necessary to neutralize the complex.

A lubricating composition comprising a major amount of a lubricant and a minor amount of a complex of tetrathiocarbonic acid, said complex being the reaction product of a mixture comprising an alkali metal salt of tetrathiocarbonic acid, a cationic complex-forming metallic moiety, and a counter ion.
