Look for shortcuts. Keep everything in good repair and carry tools.

By the way, you will obviously save gas, but not necessarily a ton of money. At that mileage, the bike will steadily need tubes and tires and parts and repairs, and you will start to think of each expense in terms of how much gas you could have purchased.
