Chevrolet Silverado Classic 2007, Owner'S Manual

Page: 474 / 676

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 475.
Notice: Some additives are not compatible
with E85 fuel and can 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 the fuel system and also damage
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 might 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.
