Oh no say it ain't so, we had to put gas in the volt so Dawn could go out of town!  I think this is only the 4th time we've put gas in it in the last 6 months with over 7300 miles of driving.  We went from April to June, and now from June to September, so about every 2 1/2 to 3 months.  In addition to only filling up every 2 to 3 months the tank is a max of 9 gallons, so it's usually around $25 to fill up.

On another note talking to a local dealer recently I've found out there are some nice lease incentives for the 2013 volts, you might want to check one out!
