During warm months we usually get better than 50 mpg, but this last tank of gas set our personal record: 57.8 mpg. We went an incredible 609 miles between fill-ups, which is darn good for gas tank that holds about 11.5 gallons and usually costs less than $30 to fill.
Ok, you can now make fun of us!
UPDATE: On our next tank of gas, we got 58.3 mpg and 625 miles. That'll probably stand as our record for quite some time!
