2009 Malibu Automobile Owner's Manual

For good starting and heater efficiency below 32°F (0°C),
the fuel mix in the fuel tank should contain no more
than 70% ethanol. It is best not to alternate repeatedly
between gasoline and E85. If you do switch fuels,
it is recommended that you add as much fuel as
possible — do not add less than three gallons (11 L)
when refueling. You should drive the vehicle immediately
after refueling for at least seven miles (11 km) to allow the
vehicle to adapt to the change in ethanol concentration.
E85 has less energy per gallon than gasoline, so you
will need to refill the fuel tank more often when using E85
than when you are using gasoline. See Filling the Tank
on page 5-10.
Notice: Some additives are not compatible with
E85 fuel and can harm the vehicle’s fuel system.
Do not add anything to E85. Damage caused
by additives would not be covered by the vehicle
warranty.
Notice: This vehicle was not designed for fuel
that contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under the vehicle
warranty.
