Use of a non-conventional synthetic basestock in the formulation of high-quality engine oils

Research has been undertaken to identify new synthetic basestocks, to be used alone or with polyalphaolefins, for the formulation of high-quality engine oils. Basestock selection was limited to products not normally used in the synthesis of ester-type basestocks. A non-conventional product was identified: a carbonic ester of synthetic alcohols. A complete engine oil has been formulated using this basestock and submitted to a full test programme. The results are reported.
