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
resellers 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. If the octane is less
than 95 RON, repairs would not be covered
by the vehicle warranty. If heavy knocking is
heard when using petrol rated at 95 RON
octane, 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.
