Fuels In Foreign Countries - Chevrolet 2007 Monte Carlo Owner's Manual

To ensure quick starts in the wintertime, the
E85 fuel must be formulated properly for your
climate according to ASTM specification D 5798.
If you have trouble starting on E85, it may be
because your E85 fuel is not properly formulated
for your climate. If this happens, switching to
gasoline or adding gasoline to your fuel tank
may improve starting. 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 your fuel tank more
often when using E85 than when you are using
gasoline. See Filling the Tank on page 303.

Notice: Some additives are not compatible
with E85 fuel and may harm your vehicle's fuel
system. Damage caused by additives would
not be covered by your new vehicle warranty.
Notice: Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in your fuel system and also damage
the plastic and rubber parts. That damage
would not be covered under your warranty.

Fuels in Foreign Countries

If you plan on driving in another country outside the
United States or Canada, the proper fuel may be
hard to find. Never use leaded gasoline or any other
fuel not recommended in the previous text on fuel.
Costly repairs caused by use of improper fuel would
not be covered by your warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business
in the country where you will be driving.
