512 STARTING AND OPERATING For best results, a refueling pattern that avoids alternating E-85 is a mixture of approximately 85% fuel ethanol and between E-85 and unleaded gasoline is recommended. When you do switch fuel types it is recommended that: 15% unleaded gasoline. Ethanol Fuel (E-85) WARNING! Ethanol vapors are extremely flammable and could cause serious personal injury. Never have any smoking materials lit in or near the vehicle when removing the fuel filler tube cap (gas cap) or filling the tank. Do not use E-85 as a cleaning agent and never use it near an open flame. Fuel Requirements If your vehicle is E-85 compatible, it will operate on unleaded gasoline with an octane rating of 87, or E-85 fuel, or any mixture of these two fuels. • You do not add less than 5 gallons (19 Liters) when refueling. • You drive the vehicle immediately after refueling for at least 5 miles (8 km). Observing these precautions will avoid possible hard starting and/or significant deterioration in driveability during warm up. NOTE: • Use seasonally adjusted E-85 fuel (ASTM D5798). With non-seasonally adjusted E-85 fuel, you may experience hard starting and rough idle following start up even if the above recommendations are followed, especially when the ambient temperature is below 32°F (0°C).
