Step 1
Use the settings option in the GPS menu to change to the shortest distance, instead of the fastest time, and push "Enter" or "Save." Less miles and lower speeds will provide you with better fuel mileage, and help you save money on the amount of gas you need.

Step 2
Go to the avoidances option in the menu of your GPS and choose to avoid cities or towns and save this selection. Cites and towns negatively affect fuel mileage by causing you to stop and go at lights and when stuck in traffic.

Step 3
Enter your destination into your machine by the method you normally would use. There are many different methods to do this, such as by address, from your favorites, or by categories such as restaurants, hotels or other popular destination points.

Review the path chosen by your GPS using a map of the region through which you will travel. Make sure that the route selected is reasonable and that you can sensibly follow it during your trip.
