Gasoline Recommendations (Can and Can’t Use)
Reformulated gasoline (RFG) is a cleaner-burning fuel. It can lower emissions of highly volatile organic compounds.
In many areas in the US RFG is required.
Therefore Jeep Gladiator strongly guides using reformulated gasoline.
Jeep Gladiator suggests using gasoline containing up to 15% ethanol (E-15).
Do not use methanol blended gasoline.
Do Not Use E-85 In Non-Flex Fuel Vehicles
Jeep Gladiator is not a flex-fuel vehicle. Using Flex-fuel or E-85 in it will render problems such as
- lean mode
- inadequate engine performance
- difficult to start and drive in cold weather
- corrosion may increase.
MMT In Gasoline
MMT is an octane enhancer.
There is no advantage to using MMT blended gasoline, else can damage the spark plug and deposit manganese particles on the engine.
The emission of manganese particles is harmful to the environment, therefore it is prohibited in federal and California.
Don’t use gasoline with MMT in Jeep Gladiator.
Materials Added To Fuel
Using TOP-TIER Detergent Gasoline can help to improve gas mileage, maintains engine performance, and lower emissions.
Fuel system clean agents can harm the fuel system gasket. So, don’t use it.
Flexible Fuel (E-85)
E-85 signifies 15% unleaded gasoline and up to 85% ethanol.
The Jeep Gladiator has two engines, 3.6L, and 3.0L. Both engines lack flex fuel abilities.
If your Gladiator with a 3.0L diesel engine, federal law requires you to fuel Gladiator with ultra-low sulfur diesel fuel grade S15 (15 ppm Sulfur maximum). And prohibit low-sulfur diesel fuel grade S500 (500 ppm Sulfur maximum).
The number 2 diesel fuel grade S15 is fine in hot and ordinary temperatures. For cold temperatures (below -7°C), use climatized or dilute the Number 2 diesel fuel with 50% Number 1 diesel fuel. Number 1 diesel fuel, grade S15, should only be used where ample icy conditions exist (-23 °C).
Biodiesel is fuel that are produce from animal fat, rapeseed oil (Rapeseed Methyl Ester base), or soybean oil (Soy Methyl Ester base).
Jeep recommend to use upto 5% biodiesel. The biodiesel B6 to B20 or higher cause premature engine wear.
