Blends of lubricant basestocks with high viscosity complex alcohol esters

A lubricating oil composition comprising an add mixture of the following components:

• (A) a complex alcohol ester basestock which is a reaction product of an add mixture of the following:
• (1) a polyhydroxyl compound selected from the group consisting of neopentyl glycol, technical grade pentaerythritol, mono-pentaerythritol, di-pentaerythritol, trimethylopropane, trimethylolethane and trimethylobutane;
• (2) a C.sub.2 -C.sub.12 polybasic acid or an anhydride of a C.sub.2 -C.sub.12 polybasic acid, providing that the ratio of equivalents of said polybasic acid to equivalents of alcohol from said polyhydroxyl compound is in the range between about 1.6:1 to 2:1;
• and (3) a C.sub.5 -C.sub.13 monohydric alcohol, provided that the ratio of equivalents of said monohydric alcohol to equivalents of said polybasic acid is in the range between about 0.84:1 to 1.2:1;
• wherein said complex alcohol ester exhibits a viscosity in the range between about 100-700 cSt at 40.degree. C. and has a polybasic acid ester concentration of less than or equal to 70 wt. %, based on said complex alcohol ester;
• and
• (B) a lubricity enhancing amount of at least one additional basestock effective to exhibit a lubricity, as measured by the coefficient of friction of the lubricating oil composition, of less than or equal to 0.15.
