metal fuel system parts or
damage plastic and rubber
parts.
.Fuel containing metals
such as
methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control
system and spark plugs.
.Fuel with a posted octane
rating of less than the
recommended fuel. Using
this fuel will lower fuel
economy and
performance, and may
decrease the life of the
emissions catalyst.
Fuels in Foreign
Countries
The U.S., Canada, and Mexico
post fuel octane ratings in
anti-knock index (AKI). For fuel
not to use in a foreign country,
see Prohibited Fuels0318.
Fuel Additives
TOP TIER Detergent Gasoline
is highly recommended for use
with your vehicle. If your
country does not have TOP
TIER Detergent Gasoline, add
ACDelco Fuel System
Treatment Plus−Gasoline to
the vehicle’s gasoline fuel tank
at every oil change or
15 000 km (9,000 mi),
whichever occurs first. TOP
TIER Detergent Gasoline and
ACDelco Fuel System
Treatment Plus−Gasoline will
help keep your vehicle’s
engine fuel deposit free and
performing optimally.
Filling the Tank
An arrow on the fuel gauge
indicates which side of the
vehicle the fuel door is on. See
Fuel Gauge 0125.
{Warning
Fuel vapors and fuel fires
burn violently and can cause
injury or death.
Follow these guidelines to
help avoid injuries to you
and others:
.Read and follow all the
instructions on the fuel
pump island.
.Turn off the engine when
refueling.
.Keep sparks, flames, and
smoking materials away
from fuel.
.Do not leave the fuel

specification are marked with
the dexos1 approved logo. See
www.gmdexos.com.
Caution
Failure to use the
recommended engine oil or
equivalent can result in
engine damage not covered
by the vehicle warranty.
Viscosity Grade
For the 2.0L L4 engine, use
SAE 0W-20 viscosity grade
engine oil.
For the 3.6L V6 engine, use
SAE 5W-30 viscosity grade
engine oil. Cold Temperature
Operation: In an area of
extreme cold, where the
temperature falls below −29 °C
(−20 °F), an SAE 0W-30 oil may be used. An oil of this
viscosity grade will provide
easier cold starting for the
engine at extremely low
temperatures.
When selecting an oil of the
appropriate viscosity grade, it
is recommended to select an
oil of the correct specification.
See
“Specification” earlier in
this section.Engine Oil Additives/
Engine Oil Flushes
Do not add anything to the oil.
The recommended oils
meeting the dexos
specification are all that is
needed for good performance
and engine protection.
Engine oil system flushes are
not recommended and could
cause engine damage not
covered by the vehicle
warranty.
What to Do with Used Oil
Used engine oil contains
certain elements that can be
unhealthy for your skin and
could even cause cancer. Do
not let used oil stay on your
skin for very long. Clean your
skin and nails with soap and
water, or a good hand cleaner.
Wash or properly dispose of
clothing or rags containing
used engine oil. See the
manufacturer's warnings
about the use and disposal of
oil products.
Used oil can be a threat to the
environment. If you change
your own oil, be sure to drain
all the oil from the filter before
disposal. Never dispose of oil
by putting it in the trash or
pouring it on the ground, into
sewers, or into streams or
bodies of water. Recycle it by
taking it to a place that
collects used oil.
