Driving and Operating
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

.
Vehicles that have a yellow fuel
cap can use either unleaded
gasoline or ethanol fuel containing
up to 85% ethanol (E85). See
Fuel
E85 (85% Ethanol) on page 9
‑
48
.
For all other vehicles, use only the
unleaded gasoline described under
Recommended Fuel on page 9
‑

.
Recommended Fuel
If the vehicle has a 2.4L L4 engine,
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 2.0L
L4 engine, 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, a
heavy knocking noise might be
heard when driving. 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.
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

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
