Your vehicle is designed to use unleaded gas- oline only. It is equipped with a fuel tankfiller pipe specifically designed to accept only a small diameter unleaded gasoline dispens- ing nozzle. In the United States, fuel suppliers are required by law to add detergents to their gas-
oline to minimize fuel-injector clogging and minimize intake-valve deposits. Detergent gasoline helps keep your engine in tune and your emission-control system working prop-erly. Your vehicle is designed to operate on unleaded gasoline having a minimum octanenumber of 87 [(MON+RON)/2] or 91 RON. Gasoline sold at some service stations con- tains oxygenates such as ethanol, although the oxygenates may not be identified by thosenames. Oxygenates are required in some areas of the country. Oxygenated fuel can be used in your vehicle.
A mixture of up to 10 % ethanol (grain alco- hol) and 90 % unleaded gasoline may be usedin your vehicle, provided the octane number is at least as high as that recommended for unleaded gasoline. Do not operate your vehicle on gasoline con- taining methanol (wood alcohol). Using this type of alcohol could adversely affect thevehicle’s performance and damage critical parts of the vehicle’s fuel system. Many areas of the country require the use of cleaner burning fuel referred to as “Reformu- lated Gasoline”.Reformulated gasoline contains oxygenates and is specially blended to reduce vehicle emissions and improve air quality.Mitsubishi Motors Cor
poration strongly sup-
ports the use of reformulated gasoline. Prop- erly blended reformulated gasoline has noadverse effect on vehicle performance or the durability of the engine and the fuel system.
Fuel selection
WA R N I N G Gasoline is highly flammable and explo- sive. You could be burned, seriouslyinjured or killed when handling it. When- ever you refuel your vehicle, stop the engine and keep flames, sparks, andsmoking materials away from the vehicle. Always handle fuel in well-ventilated out- door areas.CAUTION Using leaded gasoline in your vehicle will damage the engine, catalytic converter, and the oxygen sensors. Also, using leaded gaso-line is illegal, and will void your warranty coverage of the engine, catalytic converter, and oxygen sensors.

Premium fuel is recommended to improve the performance under severe conditions such as hot w

MMT is a manganese-containing metallic additive that is blended into some gasolines to increase the octane number. Mitsubishi Motors Corporation recommends using gaso-lines without MMT. Use of gasolines blended with MMT may adversely affect performance, and cause themalfunction indicator on your instrumentpanel to come on. If this happens, contact an authorized Mitsubishi Motors dealer or a repair facility of your choice for assistance. Your vehicle may have been designed to sat- isfy California’s low-emission regulationsbased on clean-burning low-sulfur gasoline. Gasoline sold in parts of the country other than California is allowed to have a highersulfur content. Using such gasoline could adversely affect the vehicle’s catalytic con- verter and cause the engine malfunction indi-cator (“SERVICE ENGINE SOON” or “Check engine light”) to come on. Illumina- tion of this indicator while using high-sulfurgasoline does not necessarily mean the vehi- cle’s emission-control system is malfunction- ing. Your authorized Mitsubishi Motors
dealer may suggest using a different, lower- sulfur brand of unleaded gasoline to deter- mine if the problem is fuel-related.

MMT (methylcyclopentadienyl manganese tricarbonyl) Sulfur in gasoline
NOTE
Poor-quality gasoline can cause problems such as hard starting, stalling during idling, abnormal engine noise, and poor accelera- tion. If you experience any of these prob-lems, try using a different brand of gasoline. If the engine malfunction indicator (“SER- VICE ENGINE SOON” or “Check enginelight”) flashes, have the vehicle inspected as soon as possible by the nearest authorized Mitsubishi Motors dealer or a repair facilityof your choice. Repeatedly driving short distances at low speeds can cause deposits to form in the fuel system and engine, resulting in hard starting and poor acceleration. If these problemsoccur, you are advised to add a detergent additive to the gasoline when you refuel the vehicle. The additive will remove the depos-its, thereby returning the engine to a normal condition. Be sure to use a Mitsubishi Motors Genuine cleaning additive. Using anunsuitable additive could make an engine malfunction. For details, please contact the nearest authorized Mitsubishi Motors dealer.
Filling the fuel tank
WA R N I N G When handling fuel, comply with the safety regulations displayed by garages and filling stations. Gasoline is highly flammable and explo- sive. You could be burned, seriously injured or killed when handling it. Whenrefueling your vehicle, always turn the engine off and keep away from flames, sparks, and smoking materials. Alwayshandle fuel in well-ventilated outdoor areas. Before removing the fuel tank filler cap, be sure to get rid of your body’s static electricity by touching a metal part of thevehicle or fuel pump. Any static electricity on your body could create a spark that ignites fuel vapor. Perform the whole refueling process (opening the fuel tank filler door, remov-ing the fuel cap, etc.) by yourself; do not let any other person near the fuel tank filler. If you allowed a person to help youand that person was carrying static elec- tricity, fuel vapor could be ignited. Do not move away from the fuel tank filler until refueling is finished. If you movedaway and did something else (for example, sitting on a seat) part-way through the refueling process, you could pick up afresh charge of static electricity.
