containing up to 85% ethanol (E85).
See Fuel E85 (85% Ethanol) on
page 9 66. For all other vehicles,
use only the unleaded gasoline
described under Recommended
Fuel on page 9 64.

Recommended Fuel

If the vehicles has the 6.0L
V8 engine (VIN Code J), 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 F), use premium
unleaded gasoline with a posted
octane rating of 91 or higher.
You can also use regular unleaded
gasoline rated at 87 octane or
higher, but the vehicle's acceleration
could be slightly reduced, and a
slight audible knocking noise,
commonly referred to as spark
knock, might be heard. If the octane
is less than 87, you might notice a
heavy knocking noise when you
drive. If this occurs, use a gasoline
rated at 87 octane or higher as
soon as possible. Otherwise, you
could damage the engine. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.

Gasoline Specifications

At a minimum, gasoline should
meet ASTM specification
D 4814 in the United States or
CAN/CGSB 3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. See Fuel Additives
on page 9 65 for additional
information.

California Fuel

Requirements

If the vehicle is certified to meet
California Emissions Standards,
it is designed to operate on fuels
that meet California specifications.
See the underhood emission control
label. If this fuel is not available in
states adopting California emissions
standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog check test.
See Malfunction Indicator Lamp on
page 5 18. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.
