2004 MAZDA MODEL 6 HATCHBACK catalytic converter

Black plate (106,1)
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.
Your Mazda will perform best with fuel listed in the table.
Fuel Octane Rating*(Anti-knock index)
Regular unleaded fuel 87 [ (R+M)/2 method] or above (91 RON or above)
* 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.
CAUTION
lUSE 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.
lYour 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.
lNever 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.
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.
lGasohol containing more than 10% ethanol.
lGasoline or gasohol containing methanol.
lLeaded fuel or leaded gasohol.

Emission Control System
Your vehicle is equipped with an emission control system (the catalytic converter is part of
this system) that enables your vehicle to comply with existing exhaust emissions
requirements.
WARNING
Parking Over Flammable Objects:
Parking over or near anything flammable, such as dry grass, is dangerous. Even with
the engine turned off, the exhaust system could ignite it because the exhaust system
gets very hot during normal use. A resulting fire could cause serious injury or death.
Never park over or near anything flammable.
CAUTION
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.
lUSE ONLY UNLEADED FUEL.
lDon't drive your Mazda with any sign of engine malfunction.
lDon't coast with the ignition switch turned off.
lDon't descend steep grades in gear with the ignition switch turned off.
lDon't operate the engine at high idle for more than 5 minutes.
lDon't tamper with the emission control system. All inspections and adjustments must
be made by a qualified technician.
lDon't try to push-start or pull-start your vehicle.
NOTE
Under U.S. federal law, any modification to the original-equipment emission control
system before the first sale and registration of a vehicle is subject to penalties. In some
states, such modification made on a used vehicle is also subject to penalties.
