Top Tier Fuel

GM recommends the use of TOP TIER
Detergent Gasoline to keep the engine
clean, reduce engine deposits, and
maintain optimal vehicle performance.
Look for the TOP TIER Logo or see
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline marketers
and applicable countries.

Recommended Fuel

Use the recommended fuel for proper
vehicle maintenance.
Use unleaded petrol with a posted
octane rating of 95 RON or higher and
with ethanol up to 10% by volume.
Unleaded petrol rated at 91 RON can
be used, but acceleration and fuel
economy will be reduced, and an
audible knocking noise may be heard.
If this occurs, use petrol rated at 95
RON as soon as possible, otherwise
the engine could be damaged. If heavy
knocking is heard when using
unleaded petrol rated at 95 RON, the
engine needs service.

Prohibited Fuels

Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
Fuel with any amount of
methanol, methylal, ferrocene,
and aniline. These fuels can
corrode 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.
