Before Driving Your Mazda
Fuel and Engine Exhaust Precautions
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 |
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.
You may use a regular unleaded fuel with an Octane Rating from 87 to 90 (91 to 95 RON) but this will slightly reduce performance, such as reduced engine output, and engine knocking.
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
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. Otherwise, the emission control system could be damaged. Consult an Authorized Mazda Dealer for details.
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. l Gasoline or gasohol containing methanol. l Leaded fuel or leaded gasohol.
