Gas mileage is such an illusive thing, with so many variables effecting it that for me it is often impossible to account for differences. However, my car gets pretty consistant around town mileage, 19 to 20 mpg. Recently I discovered a station in town that sells pure premium i.e. no ethanol and started to use it. It appears from a fairly small time sample that my mileage has jumped to 21.5 with that being the only change.
