Cost Savings
Slash your total cost of ownership.
Fleets switching from diesel to ethanol can save 40 cents per mile in their operations. On an energy-equivalent (DGE) basis, ethanol is over $2/gallon less expensive than diesel fuel.
Find out how much you could save on your fleet’s fuel costs, and request a custom total cost of ownership and emissions study.
