Understand the value provided by ethanol using this easy calculator. Ethanol has a higher octane rating than unleaded, burns cleaner, and is generally cheaper than pure unleaded gasoline. But ethanol has fewer BTU's per gallon than unleaded, so gas mileage might be a little lower than with pure unleaded gasoline. This easy calculator lets you plug in the cost of unleaded so you can see how good a deal you are getting with E-85.
NOTE: Actual mileage differences will vary based on the type of engine, vehicle and season.
