Fuel

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 regular unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 87

(R+M)/2

or higher. Do not use

gasoline with a posted octane rating
of less than 87, as this may cause
engine knock and will lower fuel
economy.

FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
