9-38 Driving and Operating Some gasolines, mainly high octane
racing gasolines, can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use
gasolines and/or fuel additives with
MMT as they will reduce spark plug
life and affect emission control
system. The malfunction indicator
lamp may turn on. If this occurs, see
your dealer for service.
California Fuel
Requirements If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle may not pass a smog-check test. See Malfunction Indicator
Lamp on page 5-11 . If this occurs,
return to your authorized dealer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs may not be
covered by the vehicle warranty.
Fuels in Foreign
Countries If planning to drive in countries
outside the U.S. or Canada, the
proper fuel might be hard to find.
Check regional auto club or fuel
retail brand websites for availability
in the country where driving. Never
use leaded gasoline, fuel containing
methanol, manganese, or any other
fuel not recommended. Costly
repairs caused by use of improper
fuel would not be covered by the
vehicle warranty. Fuel Additives To keep fuel systems clean, TOP
TIER Detergent Gasoline is
recommended. See Fuel on
page 9-37 .
If TOP TIER Detergent Gasoline is
not available, one bottle of Fuel
System Treatment PLUS added to
the fuel tank at every engine oil
change can help. Fuel System
Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Do not use additives with E85 or
FlexFuel.

10-10 Vehicle Care
{ CautionFailure to use the recommended
engine oil can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification. Use of Substitute Engine Oils if
dexos1 is unavailable: In the event
that dexos1-approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil that
meets American Petroleum Institute
(API) approved specifications of the
appropriate viscosity grade. These
oils have the API certification mark
on the front of the container.
Viscosity Grade
Use SAE 5W-30 viscosity grade
engine oil.
Engine Oil Additives/Engine
Oil Flushes Do not add anything to the oil. The
recommended oils meeting the
dexos1 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.

to the cooling system can be
dangerous. Water and other
liquids can boil before the proper
coolant mixture will. The coolant
warning system is set for the
proper coolant mixture. With
water or the wrong mixture, the
engine could get too hot but you
would not get the overheat
warning. The engine could catch
fire and you or others could be
burned. Use the recommended
engine coolant. See
Recommended Fluids and
Lubricants on page 11-11 . Use the recommended engine
coolant. See Recommended Fluids
and Lubricants on page 11-11 .
If using this coolant, nothing else
needs to be added. This coolant: .
Gives freezing protection down
to − 37°C ( − 34°F), outside
temperature. .
Gives boiling protection up to
129°C (265°F), engine
temperature. .
Protects against rust and
corrosion. .
Will not damage aluminum parts. .
Helps keep the proper engine
temperature.
{ Caution
If the improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
(Continued) Caution (Continued) mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
recommended engine coolant for
the cooling system. See
Recommended Fluids and
Lubricants on page 11-11 .
Never dispose of engine coolant by
putting it in the trash, by pouring it
on the ground, or by pouring into
