Abstract
A lubricating composition has been found for chain and gear drive mechanisms. The composition comprises a polyalphaolefin base oil, an ester oil solubilizer and 2 to 4 wt % of a polybutene tackifier. The composition replaces a mineral oil formulation and demonstrates persistent lubricity and substantially reduced smoking in chain and drive gear assemblies operated at high temperatures.
