Abstract
A synthetic oil composition comprises a major portion by weight of synthetic base oil having a kinetic viscosity of from about 1.5 to 2.5 cSt at 100.degree. C. and a minor portion by weight of one or more property enhancing additives for said base oil, said base oil comprising a major portion by weight of dimer of 1-decene, said dimer having a kinetic viscosity of less than about 250 cSt at -40.degree. C., a kinetic viscosity of less than about 1,000 cSt at -54.degree. C. and a pour point of less than about -65.degree. C.
