Not only is it possible, but too pricey at present, in the near future it will be able to make and improve fuel oil through nano-scale processing which will be able to synthesize compounds from raw materials at (one hopes) a far lower cost per ton than digging, drilling and refining gasoline.

I'd love to see the day when old landfills, for example, are mined by nanobots for the raw materials to reuse for fuels, new plastics, new steel, and other commodities.
