Gas Mileage 1.0

the author of this app says:

A HanDBase program that computes gas mileage for you. You can set the 'Grade of Gas' filter to show only regular, or premium and compare how your gas mileage is effected. You can set the date range to only show a designated period of time and see how your gas mileage changes. Sort by date, and then by Gas Station, or Grade of Gas, to track differences.
