Alternative Fuel

So My wife's Minivan is a 2001 Grand Caravan.
Well it says right in the owners manual that it is a dual fuel vehicle.
Here is the problem, There is only one Station selling alternative fuel whithin 100 miles of our house.
According to the Locator on a Government website.

Well it just doesn't make sense to drive 85 miles to fill up with E85 now does it.

Next time I am down there I am gonna look up that station just to see how it affects gas mileage.
