2011 MAZDA MODEL RX 8 octane

Black plate (130,1)
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)
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[ (RM)/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
ØUSE 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.
ØYour 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.
ØNever 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
