Deposit Cleaner
To get the best performance out of our newest-technology SKYACTIV petrol engines, cleaning of deposits adhering to the fuel related system, such as fuel injectors, may be required by using a Mazda genuine deposit cleaner in the specified countries. Refer to SCHEDULED MAINTENANCE for the details.
Refer to Scheduled Maintenance (Europe) (Search).
Refer to Scheduled Maintenance (Except Europe) (Search).
-
According to the inspection result of scheduled maintenance, Mazda genuine deposit cleaner is to be used. Neglected deposits in the fuel system may cause malfunction indicator light coming on to indicate an engine malfunction, and if the vehicle continues to be driven under this condition, it could result in problems occurring such as idling failure and poor acceleration.
-
The Mazda genuine deposit cleaner is not a guarantee of engine performance no matter the quality of the fuel used. When a problem occurs even though the specified fuel is used and the Mazda genuine deposit cleaner is used according to the instructions, consult an Authorised Mazda Dealer.
-
If a deposit cleaner other than the Mazda genuine product is used, it could result in damage to the fuel system or the engine internally; therefore use only the Mazda genuine product. Mazda genuine deposit cleaner: K002 W0 001
-
If cleaning required according to the inspection result of scheduled maintenance is not done with the Mazda genuine deposit cleaner, repair cost for engine malfunctions caused by deposits are borne by the customer.
How to use the cleaner
With the fuel tank full, infuse 1 bottle of Mazda genuine deposit cleaner directly into the fuel tank.
-
Infusing the deposit cleaner when the fuel tank is full provides the concentration of cleaner within the range effective for removing the deposits and the best cleaning results can be obtained by the full tank of fuel with the infused deposit cleaner contacting the deposits for a long period of time until the full tank of fuel is nearly used up.
Fuel Requirements (SKYACTIV-D 1.8)
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.
Emission Control System (SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5, SKYACTIV-X 2.0)
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.
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.
