Using Flex Fuel (Ethanol blended fuels such as E85, E40, E30, E20, E15, and other blends)

Only use Flex Fuel in machines that are designed to use Flex Fuel. Machines with the Flex Fuel label can use either ethanol-blended fuel containing from 0% ethanol (E0) up to 85% ethanol (E85) or regular, unleaded gasoline.

Use fresh unleaded fuel with an octane rating of 87 or higher. E85 ethanol fuel should meet ASTM Specification D5798. Intermediate blends should consist of E85 blended with regular unleaded gasoline.

When changing from one ethanol blend to another, or changing from regular, unleaded gasoline to Flex Fuel, or from Flex Fuel to regular, unleaded gasoline, it is recommended that you add as much fuel as possible, at least half a tank. Do not add less than one third of a tank of the new fuel type. It is not recommended to switch repeatedly between fuel types.

After changing to a new fuel type, run the engine for at least ten minutes to allow the machine to adapt to the ethanol blend ratio of the new fuel. You can expect a slight change in performance during that period.

Ethanol produces less energy per gallon or liter than regular, unleaded gasoline, so you will need to fill the fuel tank more frequently when using Flex Fuel.

Ethanol is a renewable fuel made from renewable sources such as corn and other crops.
