Pumping gas, I watched the numbers flash by, assuming that it would take somewhere between 12 and 13 gallons, since the tank holds 13 gallons.
As I passed 13, I started to wonder a bit. When it stopped at 13.66 gallons, I realized that my previous assumption that the tank held 13 gallons would need to be revised.
Apparently my car actually has a 14-gallon tank.
Either that or I was literally running on fumes.
Some weeks can be like that.
