Fuel - Chevrolet 2015 City Express Owner's Manual

Fuel

Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. When
driving in the U.S. and Canada, to
help keep the engine clean and
maintain optimum vehicle
performance, we recommend using
TOP TIER Detergent Gasolines.
See www.toptiergas.com for a list of
TOP TIER Detergent Gasolines.
Use regular unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 87 or
higher. Do not use gasoline with an
octane rating below 87, as it may
cause engine damage and will lower
fuel economy.
Use of Seasonal Fuels
Use summer and winter fuels in the
appropriate season. The fuels
industry automatically modifies the
fuel for the appropriate season.
If fuel is left in the vehicle tank for
long periods of time, driving or
starting could be affected. Drive the
vehicle until the fuel is at one-half
tank or less, then refuel with the
current seasonal fuel.
Prohibited Fuels
Gasolines containing oxygenates
such as ethers and ethanol, as well
as reformulated gasolines, are
available in some cities. If these
gasolines comply with the
previously described specification,
then they are acceptable to use.
Driving and Operating
Warning
Using a fuel other than what
is specified could adversely
affect the emission control
system, and may also affect
the warranty coverage.
Under no circumstances
should either a leaded
gasoline or gasoline with
MMTbe used. Doing so will
damage the catalytic
converter.
Do not use E-15 or E-85 fuel
in your vehicle. Your vehicle
is not designed to run on
E-15 or E-85 fuel. Using E-15
or E-85 fuel in a vehicle not
specifically designed for E-15
or E-85 fuel can adversely
damage the emission control
devices and systems of the
vehicle. Damage caused by
such fuel is not covered by
the new vehicle limited
warranty.
