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

Recommended Fuel (LSY
2.0L L4 Engine)
Premium unleaded gasoline meeting
ASTM specification D4814 with a
posted octane rating of 93 — (R+M)/2
— is highly recommended for best
performance and fuel economy.
Unleaded gasoline with an octane
rated as low as 87 can be used. Using
unleaded gasoline rated below
93 octane, however, will lead to
reduced acceleration and fuel
economy. If knocking occurs, use a
gasoline rated at 93 octane as soon as
possible, other wise, the engine could
be damaged. If heavy knocking is
heard when using gasoline with a
93 octane rating, the engine needs
service.
