2008 MAZDA MODEL RX 8 catalytic converter

Black plate (116,1)
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.
FuelOctane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R+M)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
This vehicle is designed to use 91[ (R+M)/2 method] (96RON) or higher gasoline for best
performance. If 91[ (R+M)/2 method] (96RON) is not available, gasoline from 87 to 90[ (R
+M)/2 method] (91 to 95RON) can be used temporarily for emergency purposes, but this
will slightly reduce performance. Fuel with gasoline from 87 to 90[ (R+M)/2 method] (91
to 95RON), driving in high temperature or low humidity conditions could cause engine
knocking.
Fuel with a rating lower than 87[ (R+M)/2 method] (lower than 91RON) could cause the
emission control system to lose effectiveness. It could also cause engine knocking and
serious engine damage.
CAUTION
Ø 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.
Ø 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.
Ø 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.
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
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.
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.
ØUSE ONLY UNLEADED FUEL.
Ø Don't drive your Mazda with any sign of engine malfunction.
Ø Don't coast with the ignition switch turned off.
Ø Don't descend steep grades in gear with the ignition switch turned off.
Ø Don't operate the engine at high idle for more than 2 minutes.
Ø Don't tamper with the emission control system. All inspections and adjustments
must be made by a qualified technician.
Ø Don't 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.
NOTE
While the engine is off, the sound of a valve opening and closing can be heard from inside and
outside of the cabin interior, however this does not indicate an abnormality. Your vehicle has a self-
checking device and it operates while the engine is off.
