ABSTRACT:
This invention relates to a process for the production of lubricating oils having a viscosity index of at least 120 and a pour point of at least -45.degree. C. by (a) oligomerizing a mixture of C5-C20 1-olefins comprising at least 2.6% w/w of 1-decene and at least 6% w/w of 1-hexene in the presence of a catalyst. The lubricating oil so formed may be hydrogenated in the presence of hydrogen to improve the oxidation stability thereof. The process is particularly suited to olefins feeds produced during a Fischer-Tropsch synthesis in which carbon monoxide and hydrogen are passed over a heated catalyst.
