This invention discloses an oil soluble polyether composition, comprising: Image wherein R is either a C14-20 alkyl or C9-12 alkylphenyl; A is Image where x is from 7 to 13; i, j, k, and l are each independently from 0 to 35 and the sum (i + j + k + l) is from 8 to 35; o, p, and q are each independently 0 to 1 and the sum (o + p + q) is from 0 to 3; and, the average mole ratio of the glycidyl ether monomeric unit A to the initiator unit RO is from 0.4:1 to 1.5:1. This invention also discloses an anionic polymerization process for producing an oil soluble polyether composition, comprising reacting a mixture of propylene oxide and a C8-14 alkyl glycidyl ether with an initiator obtained from the group consisting of a C14-20 alkanol and a C9-12 alkylphenol under the influence of an alkaline metai alkoxide catalyst.
