ABSTRACT:
An oil-based corrosion inhibitor composition for use in lubricating and/or hydraulic oils includes an oil-soluble sulfonate salt, an imidazoline salt of a fatty acid or a poly acid, and a polymerized ester, with the corrosion inhibitor composition being diluted with a polyalphaolefin to a suitable viscosity for subsequent use as an additive to such oils. In preferred embodiments, the corrosion inhibiting additive composition is mixed with the lubricating and/or hydraulic oils at a concentration of between about 2–5% by weight of the combination.
