Fuel and Emission

Fuel and Engine Exhaust Precautions

▼ 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.

To achieve maximum engine performance, use the specified fuel.

Fuel

Octane Rating^*1 (Anti-knock index)

Regular unleaded fuel

87 [(R+M)/2 method] or above (91 RON or above)

^*1

U.S. federal law requires that octane ratings be posted on gas station pumps.

Fuel with a rating lower than 87 octane (91 RON) will negatively affect the emission

control system performance and could also cause engine knocking and serious

engine damage.

CAUTION

¾ 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.

¾ 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 gasoline contains any methanol. Stop using gasohol of

any kind if your vehicle engine is performing poorly.

¾ Never add fuel system additives other than a Mazda genuine product, 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".

Vehicle damage and drivability problems resulting from the use of the following may

not be covered by the warranty.

^ Gasohol containing more than 10 % ethanol.

^ Gasoline or gasohol containing methanol.

^ Leaded fuel or leaded gasohol.
