GASLOG tracks your gas usage, cost, and mileage. It will also graph your

Option 2 allows you to calculate the average MPG and the total cost,
mileage, and gallons used between two dates. You are given this information
and then asked if you want a graph of the MPGs for that period. The graph
will work only for EGA or better.
Option 3 lets you change to a different file and option 4 exits the
