Grand Caravan V6-4.0L (2008)
Fuel: Description and Operation
FUEL REQUIREMENTS
Your engine is designed to meet all emissions regulations and provide excellent fuel economy and performance when using high quality unleaded
gasoline having an octane rating of 87. The use of premium gasoline is not recommended. The use of premium gasoline will provide no benefit over high
quality regular gasoline, and in some circumstances may result in poorer performance.
Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and
immediate service is required. Engine damage resulting from operation with a heavy spark knock may not be covered by the new vehicle warranty.
Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturers world-wide have issued and endorsed consistent gasoline specifications (the Worldwide Fuel Charter, WWFC) to define fuel
properties necessary to deliver enhanced emissions, performance and durability for your vehicle. Chrysler recommends the use of gasolines that meet the
WWFC specifications if they are available.
REFORMULATED GASOLINE
Many areas of the country require the use of cleaner burning gasoline referred to as "reformulated" gasoline. Reformulated gasoline contain oxygenates,
and are specifically blended to reduce vehicle emissions and improve air quality.
Chrysler strongly supports the use of reformulated gasoline. Properly blended reformulated gasoline will provide excellent performance and durability
for the engine and fuel system components.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with oxygenates such as 10% ethanol, MTBE, and ETBE. Oxygenates are required in some areas of the
country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.
CAUTION: DO NOT use gasoline containing METHANOL. Gasoline containing methanol may damage critical fuel system components.
MMT IN GASOLINE
MMT is a manganese-containing metallic additive that is blended into some gasoline to increase octane. Gasoline blended with MMT provide no
performance advantage beyond gasoline of the same octane number without MMT. Gasoline blended with MMT reduce spark plug life and reduce
emission system performance in some vehicles. Chrysler recommends that gasoline free of MMT be used in your vehicle. The MMT content of gasoline
may not be indicated on the gasoline pump; therefore, you should ask your gasoline retailer whether or not his/her gasoline contains MMT.
It is even more important to look for gasoline without MMT in Canada because MMT can be used at levels higher than allowed in the United States.
MMT is prohibited in Federal and California reformulated gasoline.
SULFUR IN GASOLINE
If you live in the northeast United States, your vehicle may have been designed to meet California low emission standards with Cleaner-Burning
California reformulated gasoline with low sulfur. If such fuels are not available in states adopting California emission standards, your vehicles will
operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be adversely affected. Gasoline sold outside
of California is permitted to have higher sulfur levels which may affect the performance of the vehicle's catalytic converter. This may cause the
Malfunction Indicator Lamp (MIL), Check Engine or Service Engine Soon light to illuminate. Chrysler recommends that you try a different brand of
unleaded gasoline having lower sulfur to determine if the problem is fuel related prior to returning your vehicle to an authorized dealer for service.
CAUTION: If the Malfunction Indicator Lamp (MIL), Check Engine or Service Engine Soon light is flashing, immediate service is required.
MATERIALS ADDED TO FUEL
All gasoline sold in the United States and Canada are required to contain effective detergent additives. Use of additional detergents or other additives is
not needed under normal conditions.
FUEL SYSTEM CAUTIONS
CAUTION: Follow these guidelines to maintain your vehicle's performance:
-
The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance, damage the emission control system,
and could result in loss of warranty coverage.
