Fuel and Engine Exhaust Precautions

▼ Fuel Requirements (SKYACTIV-G 2.5)
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
Premium unleaded fuel
(within E20)
Regular unleaded fuel
Fuel with a lower rating will negatively affect the emission control system performance and
could also cause engine knocking and serious engine damage.
CAUTION
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.
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.
