Fuel Requirements(2.0-liter engine)
Vehicles equipped with catalytic
converters must use ONLY
UNLEADED FUEL, which will
reduce exhaust emissions and keep
spark plug fouling to a minimum.
Your Mazda will perform best with
regular unleaded fuel having an octane
rating (antiknock index) of at least 87
[(R+M)/2 method].
Fuel with a lower rating could cause
the emission control system to lose
effectiveness. It could also cause
engine knocking and serious engine
damage. (2.5-liter engine)
Vehicles equipped with catalytic
converters must use ONLY
UNLEADED FUEL, which will
reduce exhaust emissions and keep
spark plug fouling to a minimum.
Your Mazda will perform best with
premium unleaded fuel having an
octane rating (antiknock index) of at
least 91 [(R+M)/2 method].
You may use a regular unleaded
gasoline with a rating from 87 to 90;
this will slightly reduce performance.
Also, fuel with a rating lower than 87
octane could cause the emission
control system to lose effectiveness. It
could also cause engine knocking and
serious engine damage.
U.S. federal law requires that octane
ratings be posted on gasoline station
pumps.

CAUTION
!
NEVER USE LEADED FUEL.
It is harmful to the catalytic
converter. The lead will
accumulate on the oxygen sensor
and the catalyst inside the
converter.
This will result in a malfunction of
the emission control system,
causing poor performance.
Gasoline blended with oxygenates
such as alcohol or ether compounds
are generally referred to as oxygenated
fuels. The common gasoline blend that
can be used with your vehicle is
ethanol blended at no more than 10%.
Gasoline containing alcohol, such as
ethanol or methanol, may be marketed
under the name “Gasohol”.
CAUTION
!
Your vehicle can only use
oxygenated fuels containing no
more than 10% ethanol by volume.
Damage to your vehicle may occur
when ethanol exceeds this
recommendation, or if the gasoline
contains any methanol.
Stop using gasohol of any kind if
your vehicle engine is performing
poorly.

Emission Control SystemYour vehicle is equipped with an
emission control system (the catalytic
converter is part of this system) that
enables your vehicle to comply with
U.S. exhaust emissions requirements.
Under U.S. federal law, any
modification to the original-equipment
emission control system before the
first sale and registration of a vehicle
is subject to penalties. In some states,
such modification made on a used
vehicle is also subject to penalties.
