290 TECHNICAL SPECIFICATIONS
6.2L Supercharged Engine
Do not use E-85 flex fuel or ethanol blends
greater than 15% in this engine.
This engine is designed to meet all emis-
sions regulations, provide optimal fuel
economy and performance when using
high-quality unleaded “Premium” gaso-
line having a posted octane number of 91 as spec-
ified by the (R+M)/2 method. The use of 91 or
higher octane “Premium” gasoline is required in
these engines.
While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see your dealer immediately.
Use of gasoline with a lower than recommended
octane number can cause engine failure and
may void or not be covered by the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.

Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “Refor-
mulated Gasoline”. Reformulated gasoline
contains oxygenates and are specifically
blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recom-
mended. Properly blended reformulated gaso-
line will provide improved performance and
durability of engine and fuel system compo-
nents.
Materials Added To Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy,
reduce emissions, and maintain vehicle perfor-
mance.
Designated TOP TIER Detergent Gaso-
line contains a higher level of deter-
gents to further aide in minimizing
engine and fuel system deposits.
When available, the usage of TOP TIER Deter-
gent gasoline is recommended. Visit
