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.
Fuel
Premium unleaded fuel
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
This vehicle is designed to use 93 [ (R+M)/2 method] (98RON) or higher gasoline for best
performance. If 93 [ (R+M)/2 method] (98RON) is not available, 91 or 92 [ (R+M)/2
method] (96 or 97RON) gasoline can be used. In case 91 or 92 [ (R+M)/2 method] (96 or
97RON) is not available, gasoline as low as 87 [ (R+M)/2method] (91RON) can be used
temporarily for emergency purposes. Use of gasoline lower than 93 [ (R+M)/2 method]
(98RON) can decrease performance during its use.
USE ONLY UNLEADED FUEL.
l
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
l
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
l
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.
Gasohol containing more than 10% ethanol.
l
Gasoline or gasohol containing methanol.
l
Leaded fuel or leaded gasohol.
