Fuel selection
Your vehicle is designed to use unleaded gasoline only. It is equipped with a fuel filler tube especially designed to accept only a small diameter unleaded gasoline dispensing nozzle.
Gasoline detergent additives
In the United States, fuel suppliers are required by law to add detergents to their gasoline to minimize fuel-injector fouling and minimize intake-valve deposits. Detergent gasoline helps keep your engine in tune and your emission-control system working properly.
Octane requirement 2.4 liter engine model
Your vehicle is designed to operate on unleaded gasoline hav- ing a minimum octane number of 87 [(MON+RON)/2], or 91 RON. 3.8 liter engine model
Unleaded gasoline having an octane number of 87 [(MON+RON)/2] or 91 RON may be used, but Mitsubishi Motors Corporation recommends that your vehicle be operated on premium grade unleaded gasoline having a minimum octane number of 91 [(MON+RON)/2], or 95 RON. For maximum performance, premium gasoline is recommended. MON: Motor Octane Number RON: Research Octane Number Oxygenated gasoline
Gasoline sold at some service stations contains oxygenates such as ethanol and MTBE, although the oxygenates may not be identified by those names. Oxygenates are required in some areas of the country. Such fuel can be used in your vehicle.
WARNING! ● Gasoline is highly flammable and explosive. You
could be burned, seriously injured or killed when handling it. Whenever you refuel your vehicle, stop the engine and keep flames, sparks, and smoking materials away from the vehicle. Always handle fuel in well-ventilated outdoor areas.
CAUTION! ● Using leaded gasoline in your vehicle will damage
the engine, catalytic converter, and the oxygen sen- sors. Also, using leaded gasoline is illegal, and will void your warranty coverage of the engine, catalytic converter, and oxygen sensors.
General information
Ethanol (Gasohol)
A mixture of up to 10 % ethanol (grain alcohol) and 90 % unleaded gasoline may be used in your vehicle, provided the octane number is at least as high as that recommended for unleaded gasoline. Methanol
Do not operate your vehicle on gasoline containing methanol (wood alcohol). Using this type of alcohol could adversely affect the vehicle’s performance and damage critical parts of the vehicle's fuel system. Reformulated gasoline
Many areas of the country require the use of cleaner burning fuel referred to as “Reformulated Gasoline”. Reformulated gasoline contains oxygenates and is specially blended to reduce vehicle emissions and improve air quality. Mitsubishi Motors Corporation strongly supports the use of reformulated gasoline. Properly blended reformulated gasoline has no adverse effect on vehicle performance or on the durabil- ity of the engine and fuel system. MMT (methylcyclopentadienyl manganese tri- carbonyl)
MMT is a manganese-containing metallic additive that is blended into some gasolines to increase the octane number. Mitsubishi Motors Corporation recommends using gasolines without MMT. Use of gasolines blended with MMT may adversely affect per- formance, and cause the malfunction indicator on your instru- ment panel to come on. If this happens, contact an authorized Mitsubishi Motors dealer or a repair facility of your choice for assistance.
Sulfur in gasoline
Your vehicle may have been designed to satisfy California’s low-emission regulations based on clean-burning low-sulfur gasoline. Gasoline sold in parts of the country other than Cali- fornia is allowed to have a higher sulfur content. Using such gasoline could adversely affect the vehicle's catalytic converter and cause the engine malfunction indicator (“SERVICE ENGINE SOON” or “CHECK ENGINE”) to come on. Illumi- nation of this indicator while you are using high-sulfur gaso- line does not necessarily mean the vehicle’s emission-control system is malfunctioning. Your authorized Mitsubishi Motors dealer may suggest you try using a different, lower-sulfur brand of unleaded gasoline to determine whether the problem is fuel-related. NOTE
● Poor-quality gasoline can cause problems such as poor starting, stalling during idling, abnormal engine noise, and poor acceleration. If you experience any of these prob- lems, try using a different brand of gasoline. If the engine malfunction indicator (“SERVICE ENGINE SOON” or “CHECK ENGINE”) flashes, have the vehicle inspected as soon as possible by the nearest authorized Mitsubishi Motors dealer or a repair facility of your choice.
General information
● Repeatedly driving short distances at low speeds can cause deposits to form in the fuel system and engine, resulting in poor starting and poor acceleration. If these problems occur, you are advised to add a detergent addi- tive to the gasoline when you refuel the vehicle. The addi- tive will remove the deposits, thereby returning the engine to a normal condition. Be sure to use a genuine Mitsubishi detergent additive. Using an unsuitable additive could make the engine malfunction. For details, please contact the nearest authorized Mitsubishi Motors dealer.
