Use of the recommended fuel
is an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Look for the TOP TIER label on the
fuel pump to ensure gasoline meets
enhanced detergency standards
developed by auto companies.
A list of marketers providing
TOP TIER Detergent Gasoline can
be found at www.toptiergas.com.
The eighth digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle's engine.
The VIN is at the top left of the
instrument panel. See Vehicle
Identification Number (VIN) on
page 12‑1.
Recommended Fuel
If the vehicle has the 3.6L V6 engine
(VIN Code D), use regular unleaded
gasoline with a posted octane
rating of 87 or higher. If the octane
rating is less than 87, an audible
knocking noise, commonly referred
to as spark knock, might be heard
when driving. If this occurs, use
a gasoline rated at 87 octane or
higher as soon as possible. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.
If the vehicle has the 6.2L V8
engine (VIN Code W) or the 6.2L
V8 engine (VIN Code J), use
premium unleaded gasoline with
a posted octane rating of 91 or
higher. For best performance, use
premium unleaded gasoline with
a posted octane rating of 93.
