Abstract

The present invention relates to compositions of automotive engine oils using synthetic polyalphaolefins derived from olefins other than 1-decene, especially 1-dodecene, to improve engine oil performance, as demonstrated by the severe Volkswagen T-4, Volkswagen TDI, and Sequence IIIE tests.
