3.6L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15% in this engine.
These engines are designed to meet all emissions regulations and provide opti- mum fuel economy and performance when using high quality unleaded “Regular” gasoline having a posted oc- tane number of 87 as specified by the (R+M)/2 method. The use of higher
octane “Premium” gasoline is not required, as it will not provide any benefit over “Regular” gasoline in these
Poor quality gasoline can cause problems such as hard starting, stalling, and hesitations. If you experience these symptoms, try another brand of gasoline before consider- ing service for the vehicle.

While operating on gasoline with an octane number of 87, hearing a light knocking sound from the engine is not a cause for concern. However, if the engine is heard making a heavy knocking sound, see an dealer immediately. Use of gasoline with an octane number lower than 87 can cause engine failure and may void or not be covered by the New Vehicle Limited Warranty.

Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline”. Reformulated gasoline contains oxygenates and are specifi- cally blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Prop- erly blended reformulated gasoline will provide improved performance and durability of engine and fuel system components.
Besides using unleaded gasoline with the proper octane rating, gasolines that contain detergents, corrosion and stability additives are recommended. Using gasolines that have these additives will help improve fuel economy, reduce emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gaso- line contains a higher level of detergents to further aide in minimizing engine and fuel system deposits. When avail- able, the usage of TOP TIER Detergent gasoline is recommended. Visit www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents should be avoided. Many of these materials intended for gum and varnish removal may contain active solvents or similar ingredients. These can harm fuel system gasket and dia- phragm materials.
Some fuel suppliers blend unleaded gasoline with oxygen- ates such as ethanol.

Problems that result from using gasoline containing more than 15% ethanol (E-15) or gasoline containing methanol are not the responsibility of the manufacturer and may void or not be covered under New Vehicle Limited War- ranty.
Modifications that allow the engine to run on Compressed Natural Gas (CNG) or Liquid Propane (LP) may result in damage to the engine, emissions, and fuel system compo- nents. Problems that result from running CNG or LP are not the responsibility of the manufacturer and may void or not be covered under the New Vehicle Limited Warranty.
Methylcyclopentadienyl Manganese Tricarbonyl (MMT) is a manganese-containing metallic additive that is blended
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
into some gasoline to increase octane. Gasoline blended 9
containing up to 15% ethanol (E-15). Use of gasoline with higher ethanol content may void the New Vehicle Limited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel, the engine will have some or all of these symptoms:
with MMT provides no performance advantage beyond gasoline of the same octane number without MMT. Gaso- line blended with MMT reduces spark plug life and reduces emissions system performance in some vehicles. The manufacturer recommends that gasoline without 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 the gasoline contains MMT. MMT is prohibited in Federal and California reformulated gasoline.
NOTE: Intentional tampering with the emissions control system can result in civil penalties being assessed against you.
