If you have 100% gasoline (not E-10/E-12/E-15) available I would absolutely run that. You will get better mileage.
As far as running rough, you made it sound like its been sitting a long time? If so, pump out the fuel and replace it with fresh juice. Replace the fuel filter(s) while you are at it (likely sucked up a lot of junk)
