ABSTRACT:
Solvent-free lubricant compositions having improved lubricity properties comprising a basestock having a kinematic viscosity of about 1.5 to 3.0 cSt at 100.degree. C., about 3 to 15 wt % of bright stock having a kinematic viscosity about 20 to 40 cSt at 100.degree. C., about 3 to 15 wt % of a polyisobutylene having a number average molecular weight of about 400 to 1050 and about 3 to 15 wt % of a polyisobutylene having a number average molecular weight of about 1150 to 1650. Minor amounts of the lubricant composition may be incorporated into a distillate fuel to provide a lubricant oil-fuel composition for two-cycle engines.
