Fuel selection

Your vehicle is designed to use unleaded gasoline only. It is equipped with a fuel filler pipe especially designed to accept only a small diameter unleaded gasoline dispensing nozzle.
WARNING
Gasoline is highly flammable and explosive. You could be burned or seriously injured when handling it. When refueling your vehicle, always turn the engine off and keep away from flames, sparks, and smoking materials. Always handle fuel in well-venti­lated outdoor areas.
CAUTION
Using leaded gasoline in your vehicle will damage the engine, catalytic converter, and the oxygen sen­sors. Also, using leaded gasoline is illegal, and will void your warranty coverage of the engine, catalytic converter, and oxygen sensors.
Gasoline additives
Many fuel suppliers add detergents to their gasoline to mini­mize fuel injector fouling and to control intake valve deposits. These detergent gasolines are highly recommended for use in your vehicle. They help keep your engine in tune and your emission control system working properly.


Octane requirement
Your vehicle is designed to operate on unleaded gasoline having a minimum octane rating of 87 [(MON+RON)/2] or 91 RON.
MON: Motor Octane Number
RON: Research Octane Number
Oxygenated gasoline
Gasoline sold at some service stations may contain oxygenates such as ethanol methanol, and MTBE (Methyl Tertiary Butyl Ether), although they may not be identified by those names. Oxygenates are required in some areas of the country. Fuels blended with these oxygenates may be used in your vehicles.
Ethanol (Gasohol)
A mixture of 10% ethanol (grain alcohol) and 90% unleaded gasoline may be used in your vehicle, provided the octane rat­ing is at least as high as that recommended for unleaded gaso­line.
Methanol
Do not operate your vehicle on gasoline containing methanol (wood alcohol). The use of this type of alcohol can result in vehicle performance problems and could damage critical fuel system parts.
MTBE (Methyl Tertiary Butyl Ether)
A mixture of unleaded gasoline and 15% or less MTBE may be used in your vehicle provided the octane rating is at least as high as that recommended for unleaded gasoline. Fuel containing more than 15% MTBE may cause reduced vehicle performance, vapor lock, or difficulty in starting.
Reformulated gasoline
Many areas of the country require the use of cleaner burning
fuel referred to as "Reformulated Gasoline".
Reformulated gasolines contain oxygenates, and are specially blended to reduce vehicle emissions and improve air quality. Mitsubishi strongly supports the use of reformulated gasolines. Properly blended reformulated gasolines should have no adverse effects on vehicle performance or the durability of engine and fuel system components.
MMT
MMT is a manganese-containing metallic additive that is blended into some gasolines to increase the octane number. Gasolines blended with MMT offer no performance advantage over gasolines of the same octane number that do not contain MMT. Gasolines blended with MMT may adversely affect the spark plug and emission systems.
Mitsubishi Motors Corporation recommends using gasolines without MMT.
Sulfur in gasoline
Your vehicle may have been designed to meet California low emission standards based on clean burning low sulfur gasoline. Gasoline sold outside of California is allowed to have higher sulfur levels that may affect the performance of your vehicle's catalytic converter. This may cause the engine malfunction indicator light ("SERVICE ENGINE SOON" or "Check engine light") to come on.
Seeing this light while operating on high sulfur gasoline does not necessarily mean your emission control system is malfunc­tioning. If this happens, your authorized Mitsubishi dealer may recommended that you try using a different brand of unleaded


gasoline having a lower sulfur content to determine if the prob­lem is fuel related.
NOTE
• Poor quality gasoline can cause problems such as diffi­culty in starting, stalling, engine noise and hesitation. If you experience these problems, try another brand and/or grade of gasoline.
If the engine malfunction indicator light ("SERVICE ENGINE SOON" or "Check engine light") is flashing, have the system checked as soon as possible at an autho­rized Mitsubishi dealer.
