PURPOSE: To obtain a composition used to inhibit intermetallic friction by distilling a mixture comprising component A containing a specified metal salt, a vegetable oil and an oleic ester after heating, adding at least one specified additive and petroleum oil to the distillation residue and heating the resulting mixture.

CONSTITUTION: A mixture comprising 0.5-1.5 vol.% component A prepared by dispersing powdery FeCl3 and at least one member selected among powdery PbO, Fe2O3, Fe3C, Cr3C2 and WC, 0.5-1.5 vol.% vegetable oil and 0.5-1.5 vol.% oleic ester is heated to about 38°C under agitation. This mixture is distilled; the distillation residue is mixed with 10-20 vol.% polar hydrocarbon, 0.5-2.0 vol.% antioxidant, 0.2-1.0 vol.% carbonyl, 0.2-1.0 vol.% carbonamide, 25-40 vol.% viscosity improper, 0.5-2.0 wt.% pressure-sensitive adhesive, 0.5-3.0 vol.% sulfonate, and 40-60 vol.% petroleum oil; and the resultant mixture is heated to 38-66°C to obtain a chemical metal- and oil-treating composition.
