Abstract (en)

[origin: EP0913455A2] Lubricating compositions are described which contain organomolybdenum compounds and sulfur compounds (donors). The copper corrosion of said compositions is reduced by reacting the sulfur donors with plant oils to reduce sulfur activity and thus copper corrosion prior to the sulfur donors being added to the majority of oil to form a lubricating composition.
