Fuel and Engine Exhaust Precautions
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.
Your Mazda will perform best with fuel listed in the table.
*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.
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 Mazda warranty.
•Gasohol containing more than 10% ethanol.
•Gasoline or gasohol containing methanol.
•Leaded fuel or leaded gasohol.
Fuel Requirements
Fuel Octane Rating* (Anti-knock index)
Regular unleaded fuel 87 [ (R+M)/2 method] or above (91 RON or above)
•USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter or the oxygen sensor. The lead will
accumulate on the oxygen sensor and the catalyst inside the converter. This will result
in a malfunction of the emission control system, causing poor performance.
•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.
•Never add fuel system additives. Never add cleaning agents other than those specified
by Mazda. Other cleaning agents and additives may damage the system. Consult an
Authorized Mazda Dealer.
