2012 MAZDA MODEL 3 4-DOOR fuel

Black plate (150,1)
Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.
MZR 2.3 DISI Turbo
Your Mazda will perform best with fuel listed in the table.
FuelOctane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R
M)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
This vehicle is designed for and requires use of premium unleaded fuel. If 91 octane fuel [
(R
M)/2 method] (96RON) is not available, gasoline as low as 87 octane [ (RM)/2
method] (91RON) can be used temporarily for emergency purposes. Use of gasoline lower
than 91 octane [ (R
M)/2 method] (96RON) can decrease performance during its use.
Refueling the vehicle with the correct octane fuel a couple of times will restore vehicle
performance.
SKYACTIV-G 2.0, MZR 2.0 and MZR 2.5
Your Mazda will perform best with fuel listed in the table.
Fuel Octane Rating*(Anti-knock index)
Regular unleaded fuel 87 [ (R
M)/2 method] or above (91 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause the emission control system
to lose effectiveness. It could also cause engine knocking and serious engine damage.
CAUTION
Ø USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead
to deterioration of the emission control system and or failures.
Ø 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.
Ø Never add fuel system additives. Otherwise, the emission control system could be
damaged. Consult an Authorized Mazda Dealer for details.
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 ”.

Emission Control System
Your vehicle is equipped with an emission control system (the catalytic converter is part of
this system) that enables your vehicle to comply with existing exhaust emissions
requirements.
WARNING
Never park over or near anything flammable:Parking over or near anything flammable, such as dry grass, is dangerous. Even with
the engine turned off, the exhaust system remains very hot after normal use and
could ignite anything flammable. A resulting fire could cause serious injury or death.
CAUTION
Ignoring the following precautions could cause lead to accumulate on the catalyst
inside the converter or cause the converter to get very hot. Either condition will
damage the converter and cause poor performance.
ØUSE ONLY UNLEADED FUEL.
Ø Do not drive your Mazda with any sign of engine malfunction.
Ø Do not coast with the ignition switched off.
Ø Do not descend steep grades in gear with the ignition switched off.
Ø Do not operate the engine at high idle for more than 2 minutes.
Ø Do not tamper with the emission control system. All inspections and adjustments
must be made by a qualified technician.
Ø Do not push-start or pull-start your vehicle.
NOTE
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.
NOTE
While the engine is off, the sound of a valve opening and closing can be heard at the rear of the right
side of the vehicle, however this does not indicate an abnormality. Your vehicle has a self-checking
device and it operates while the engine is off.

Engine Exhaust (Carbon Monoxide)
WARNING
Do not drive your vehicle if you smell exhaust gas inside the vehicle:Engine exhaust gas is dangerous. This gas contains carbon monoxide (CO), which is
colorless, odorless, and poisonous. When inhaled, it can cause loss of consciousness
and death. If you smell exhaust gas inside your vehicle, keep all windows fully open
and contact an Authorized Mazda Dealer immediately.
Do not run the engine when inside an enclosed area: Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust
gas, which contains poisonous carbon monoxide, could easily enter the cabin. Loss
of consciousness or even death could occur.
Open the windows or adjust the heating or cooling system to draw fresh air when
idling the engine: Exhaust gas is dangerous. When your vehicle is stopped with the windows closed
and the engine running for a long time even in an open area, exhaust gas, which
contains poisonous carbon monoxide, could enter the cabin. Loss of consciousness or
even death could occur.
Clear snow from underneath and around your vehicle, particularly the tail pipe,
before starting the engine: Running the engine when a vehicle is stopped in deep snow is dangerous. The
exhaust pipe could be blocked by the snow, allowing exhaust gas to enter the cabin.
Because exhaust gas contains poisonous carbon monoxide, it could cause loss of
consciousness or even death to occupants in the cabin.

Turbocharger Informationí
The turbocharger greatly enhances engine power. Its advanced design provides improved
operation and requires minimum additional maintenance. To get maximum performance
from your turbocharged engine, take note of the following tips:
lThe turbocharged engine is designed for optimal operation with premium unleaded
gasoline (page 4-2). Do not use fuel with a lower octane rating. Extra fuel additives are
NOT recommended.
lChange the engine oil and filter using the turbo engine interval outlined in the
maintenance schedule (for your driving condition).
lUse only the recommended engine oil (page 8-19). Extra oil additives are NOT
recommended.
lAfter driving at freeway speeds or up a long hill, idle the engine at least 30 seconds to
cool the turbo before turning off the engine. Avoid simply shutting the engine off
abruptly after a hard or long drive. Damage to the turbocharger may result.
lDo not race or over-rev the engine when starting. This should not be done with ANY
engine, especially not with one that's turbocharged.
lDo not add any aftermarket devices to alter the engine's ignition timing, fuel delivery, or
turbo boost pressure. This may lead to serious engine damage and may void your
warranty.

NOTElIf the gears cannot be shifted down when
driving at higher speeds, the gear position
indicator will flash twice to signal that the
gears cannot be shifted down (to protect the
transaxle).
lIf the automatic transaxle fluid (ATF)
temperature becomes too high, there is the
possibility that the transaxle will switch to
automatic shift mode, canceling manual
shift mode and turning off the gear position
indicator illumination. This is a normal
function to protect the AT. After the ATF
temperature has decreased, the gear
position indicator illumination turns back
on and driving in manual shift mode is
restored.
