Premium wear-resistant lubricant containing non-ionic ashless anti-wear additives

摘要

A premium wear resistant lubricant comprises a base stock, preferably a GTL liquid or the liquid isomerization product of slack wax or F-T wax, and a non-ionic ashless anti-wear additive. The non-ionic ashless antiwear additive is preferably at least one thiazolidine. The lubricant may also contain additional base stock materials selected from other hydrocarbonaceous and synthetic base stock materials in admixture with the GTL liquid or slack wax or F-T derived base stock.
