Fuel Requirements
Vehicl es with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.
2.3-liter turbocharger engine
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] orabove (96 RON or above)
* U.S. federal law requires thatoctane ratings be posted on gasoline station pumps.
This vehicle is designed for and requires use of premium unleaded fuel. If 91 octane fuel [
(R+M)/2 method] (96RON) is not available, gasoline as low as 87 octane [ (R+M)/2
method] (91RON) can be used temporarily for emergency purposes. Use of gasoline lower
than 91 octane [ (R+M)/2 method] (96RON) can decrease performance during its use.
Refueling the vehicle with the correct octane fuel a couple of times will restore vehicle
performance.
Except 2.3-liter turbocharger engine
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] orabove (91 RON or above)
* U.S. federal law requires thatoctane ratings be posted on gasoline station pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause the emissi on control system
to lose effectiveness. It could also cause engine knocking and serious engine damage.
CAUTION
l
USE 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.
l
Your vehicl e 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.
l
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.
