octane MAZDA MODEL 6 HATCHBACK 2005 Owners Manual (in English)

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.

Fuel and Engine Exhaust Precautions

Outside the United States
Government regulations in the United States require that automobiles meet specific
emission regulations and safety standards. Therefore, vehicles built for use in the United
States may differ from those sold in other countries.
The differences may make it difficult or even impossible for your vehicle to receive
satisfactory servicing in other countries. We strongly recommend that you NOT take your
Mazda outside the United States. However, in the event that you are moving to Canada
permanently, Mazda vehicles built for use in the United States could be eligible for
exportation to Canada with specific vehicle modifications to comply with the Canadian
Motor Vehicle Safety requirements (CMVSS).
NOTE
The above is applicable for a permanent import/export situation and not related to
travelers on vacation.
You may have the following problems if you do take your vehicle outside of the United
States:
lRecommended fuel may be unavailable. Any kind of leaded fuel or low-octane fuel will
affect vehicle performance and damage the emission controls and engine.
lProper repair facilities, tools, testing equipment, and replacement parts may not be
available.
