If the vehicle has the 2.2L L4 engine (VIN Code B) or
the 2.4L L4 engine (VIN Code V), you can use either
unleaded gasoline or ethanol fuel containing up to
85% ethanol (E85). See Fuel E85 (85% Ethanol)
on
page 6‑8
. If the vehicle has the 2.0L L4 engine
(VIN Code M), use only unleaded gasoline. See
Gasoline Octane on page 6‑6.
Gasoline Octane
If the vehicle has the 2.2L L4 engine (VIN Code B), 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 2.4L L4 engine (VIN Code V)
or the 2.0L L4 engine (VIN Code M), 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 Additives
on page 6‑7
for additional
information.
