3. Historical Fuel Costs

4. Fuel costs in perspective Fuel costs are the highest operating costs for your machines. Fuel costs can exceed the original purchase price over the life of the machine. At $4 per gallon, the fuel costs are 30% - 35% of the total of the purchase price and the operating costs of the machine over a 10 year period. Engine and power train life is most closely related to fuel burned.
