ABSTRACT:
The present invention provides a gasoline composition comprising a major amount of a gasoline suitable for use in spark-ignition engines, a minor amount of a polyalphaolefin having a viscosity at 100.degree. C. from about 2.times.10.sup.-6 m.sup.2 /s to about 2.times.10.sup.-5 m.sup.2 /s (2 to 20 centistokes), being a hydrogenated oligomer containing from 18 carbon atoms to 80 carbon atoms derived from at least one alphaolefinic monomer containing from 8 carbon atoms to 16 carbon atoms, and a minor amount of a polyoxyalkylene compound selected from glycols, mono- and diethers thereof, having number average molecular weight (M.sub.n) from about 400 to about 3000, the weight ratio of polyalphaolefin:polyoxyalkylene compound being from about 1:10 to about 10:1 and a concentrate for the preparation of such gasoline compositions.
