Fuel and Emission

Fuel and Engine Exhaust Precautions

Fuel Requirements (Australia (SKYACTIV-G 2.5, SKYACTIV-G 2.5T))

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.

To achieve maximum engine performance, use the specified fuel.

Fuel	Research Octane Number
Regular unleaded fuel (Conforming to Fuel Quality Standards Act 2000)	90 or above

Fuel with a lower rating will negatively affect the emission control system performance and could also cause engine knocking and serious engine damage.

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.
This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by volume. Damage to the vehicle may occur when ethanol exceeds this recommendation, or if the petrol contains any methanol. Stop using gasohol of any kind if your vehicle engine is performing poorly.
Never add fuel system additives, otherwise the emission control system could be damaged. Consult an expert repairer, we recommend an Authorised Mazda Repairer for details.

Petrol blended with oxygenates such as alcohol or ether compounds are generally referred to as oxygenated fuels. The common petrol blend that can be used with your vehicle is ethanol blended at no more than 10 %. Petrol containing alcohol, such as ethanol or methanol, may be marketed under the name “Gasohol”.

Vehicle damage and drivability problems resulting from the use of the following may not be covered by the Mazda warranty.

Gasohol containing more than 10 % ethanol.
Petrol or gasohol containing methanol.
Leaded fuel or leaded gasohol.

Fuel Requirements (SKYACTIV-D 2.2)

The vehicle will operate efficiently on diesel fuel with specification EN590 or the equivalent.

Never use fuel other than specification EN590 or the equivalent for your vehicle. Use of petrol or paraffin in diesel engines will result in engine damage.
Never add fuel system additives. Otherwise, the emission control system could be damaged. Consult an expert repairer, we recommend an Authorised Mazda Repairer for details.

When refuelling, always add at least 10 L (2.6 US gal, 2.2 Imp gal) of fuel.

Emission Control System (SKYACTIV-G 2.5, SKYACTIV-G 2.5T)

This vehicle is equipped with an emission control system (the catalytic converter is part of this system) that enables the vehicle to comply with existing exhaust emissions requirements.

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.

Close Warning

View Warning

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.

USE ONLY UNLEADED FUEL.
Do not drive your Mazda with any sign of engine malfunction.
Do not coast with the ignition switched off.
Do not descend steep grades in gear with the ignition switched off.
Do not operate the engine at high idle for more than 2 minutes.
Do not tamper with the emission control system. All inspections and adjustments must be made by a qualified technician.
Do not push-start or pull-start this vehicle.

Engine Exhaust (Carbon monoxide)

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 colourless, odourless, and poisonous. When inhaled, it can cause loss of consciousness and death. If you smell exhaust gas inside the vehicle, keep all windows fully open and contact an expert repairer, we recommend an Authorised Mazda Repairer 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 the 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.

Fuel-Filler Flap and Cap

When removing the fuel-filler cap, loosen the cap slightly and wait for any hissing to stop, then remove it:

Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if ingested. Fuel spray is released when there is pressure in the fuel tank and the fuel-filler cap is removed too quickly.

Before refuelling, stop the engine, and always keep sparks and flames away from the filler neck:

Fuel vapour is dangerous. It could be ignited by sparks or flames causing serious burns and injuries.

Additionally, use of the incorrect fuel-filler cap or not using a fuel-filler cap may result in a fuel leak, which could result in serious burns or death in an accident.

Do not continue refuelling after the fuel pump nozzle shuts off automatically:

Continuing to add fuel after the fuel pump nozzle has shut off automatically is dangerous because overfilling the fuel tank may cause fuel overflow or leakage. Fuel overflow and leakage could damage the vehicle and if the fuel ignites it could cause a fire and explosion resulting in serious injury or death.

Close Warning

View Warning

Always use only a designated Mazda fuel-filler cap or an approved equivalent, available at an expert repairer, we recommend an Authorised Mazda Repairer. The wrong cap can result in a serious malfunction of the fuel and emission control systems.

Refuelling

Before refuelling, close all the doors, windows, and the liftgate/boot lid, and switch the ignition OFF.

To open the fuel-filler flap, pull the remote fuel-filler flap release.
To remove the fuel-filler cap, turn it anticlockwise.
Attach the removed cap to the inner side of the fuel-filler flap.
Insert the refuelling nozzle all the way and begin refuelling. Pull out the refuelling nozzle after the refuelling stops automatically.
To close the fuel-filler cap, turn it clockwise until a click is heard.
To close, press the fuel-filler flap until it locks securely.
