One of the MORE INFORMATIONs which is not important is the size of the fuel tank.

IGNORING traveling time:

NEAR
5%2A3.39%2B2%2A2.1%281%2F25%29%2A3.87
17.6

FAR
5%2A2.99%2B2%2A8.2%281%2F25%29%2A3.87
17.49

These costs are not significantly different.

The travel time IS significant. 18 minutes round trip for the neighborhood store is much better than 50 minutes for the store accross-town.
