types of gasoline we can and can’t use
Use Top tier gasoline to protect engines from carbon buildup – which can result in a rough idle, hesitation, heavy engine knocking sound, and diminished fuel economy. Here are the types of gasoline we use in Jeep Wagoneer.
Reformulated Gasoline (RFG)
RFG is cleaner burning gasoline. It can reduce emission of toxic pollutants.
These areas in the US (Los Angeles-Anaheim-Riverside, San Diego County, Greater Connecticut, New York-Northern New Jersey-Long Island-Connecticut, Philadelphia-Wilmington-Trenton, Chicago-Gary-Lake County, Baltimore, Houston-Galveston-Brazoria, and Milwaukee-Racine) require reformulated gasoline.

Meterial add to Fuel
The TOP-TIER detergent additives are crucial because they can clean fuel system components and stem deposits on the engine combustion system.
NOTICE: Don’t use fuel system cleaning agents. these can damage the fuel system gasket and diaphragm materials.
Gasoline/Oxygenate Blends
Oxygenate blend is mixing cost-effective ethanol or methanol with unleaded gasoline.
The Jeep Wagoneer can only use gasoline containing up to 15% ethanol and no methanol.
Flex Fuel (E-85)
The E-85 blend contains up to 85% ethanol and 15% unleaded gasoline.
The Jeep Wagoneer lacks flex-fuel capabilities.
Using flex-fuel in Wagoneer will result in lean mode, poor engine performance, cold start, cold driveability, and fuel system component corrosion.
MMT in Gasoline
MMT is used in unleaded gasoline as an octane booster.
The MMT form manganese particles that affect the environment, deposit on engine and fuel system component, and reduce the spark plug life.
Thus Jeep Wagoneer stops to use of gasoline with MMT.
