Which solutes are soluble in non-polar solvents?
Well, ethanol and higher alcohols for one........
And also other non-polar solutes; e.g. iodine, other hydrocarbons, i.e. butane, ethane, propane etc. And gasoline of course is itself a mixture of hydrocarbons, isomeric pentane, hexanes, and heptanes, all of which are mutually soluble.
