Use of polyalfaolefins (pao) derived from 1-dodecene or 1-tetradecene to improvethermal stability in engine oil in an internal combustion engine

摘要

The present invention relates to compositions of automotive engine oils using synthetic poly alpha olefins 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.
