1. A solvent for extracting oil from an oil bearing material so as to form an extracted oil comprised of greater than 95% by weight triglycerides and other non-polar constituents, with said solvent having a polarity no greater than about 0 and a viscosity ranging between about 0.3 centipoise and about 2.6 centipoise, whereby the triglycerides are miscible in said solvent at a temperature ranging between about 35°

  • C. and about 55°

    C and after extraction of the triglycerides said solvent and the triglycerides form a miscella at a temperature ranging between about 15°

    C. and about 25°

    C., said miscella will form distinct solvent and oil layers that can be separated, said solvent comprising;

    (a) an amount of a low molecular weight hydrocarbon having a viscosity of less than 2.6 centipoise; and

    , (b) a fluorocarbon solvent.
