Can You Put E85 in a Jeep Wrangler

can you put e85 in a jeep wrangler

As more and more people become aware of the impact of fossil fuels on the environment, alternative fuel options are becoming increasingly popular. One such alternative is E85, a fuel blend that contains 85% ethanol and 15% gasoline. E85 is primarily used in flexible-fuel vehicles (FFVs), which are designed to run on either gasoline or ethanol blends.

But can you put E85 in a Jeep Wrangler? The short answer is yes, you can put an E85 in a Jeep Wrangler, but there are several factors you need to consider before doing so. This article will discuss these factors and other related information about using E85 in a Jeep Wrangler.

What is an E85?

E85 is a fuel blend of up to 85% ethanol and gasoline. Ethanol is an alcohol made from various renewable resources, such as corn, sugarcane, and other agricultural products.

E85 is often used as an alternative fuel in flex-fuel vehicles (FFVs), which are designed to run on either E85 or gasoline. Flex-fuel vehicles have a special sensor in the fuel line that detects the ethanol content of the fuel and adjusts the engine accordingly.

Using E85 as a fuel has several potential benefits, such as reducing dependence on fossil fuels, lowering greenhouse gas emissions, and supporting the agricultural industry. However, there are also some drawbacks to using E85, such as lower fuel efficiency and availability.

The use of E85 is more common in areas with a strong agricultural industry or where there are incentives to promote the use of alternative fuels. The availability of E85 at fuel stations can vary widely depending on the region, with some areas having many E85 fuel stations and others having few or none.

Factors to Consider When Using E85 to Jeep Wrangler

Using an E85 on your Jeep Wrangler will require considering various factors affecting your vehicle. Please see below:

Vehicle Compatibility

First, not all vehicles are designed not to run on E85. You should check the vehicle’s owner’s manual to see if your Jeep Wrangler is compatible with E85. If it is not, using E85 could damage your engine or void your vehicle warranty.

When determining whether your Jeep Wrangler is an FFV, you can check the owner’s manual or look for a yellow gas cap. The yellow gas cap indicates the vehicle is designed to run on E85.

Impact on Vehicle’s Performance

Assuming you have an FFV Jeep Wrangler, the next thing to consider is the impact of E85 on the vehicle’s performance. E85 has a lower energy content than gasoline, which means that it can reduce fuel efficiency. In other words, you may need to refuel more frequently using E85 instead of gasoline.

E85 can also cause some problems with engine performance if it is not handled correctly. Ethanol can attract moisture, which can lead to corrosion in the fuel system. This can result in decreased engine performance, stalling, or other issues. Additionally, E85 can be more corrosive than gasoline, which means it can wear down rubber and plastic components in the fuel system over time.

Availability of E85

Another consideration is the availability of E85. While E85 is becoming more widely available, it is still less common than traditional gasoline. If you plan to use E85 regularly, you must ensure there are E85 fueling stations in your area.

Environmental Impact

It is also essential to consider the environmental impact of using E85. Ethanol is a renewable source which can reduce greenhouse gas emissions. However, ethanol production requires a significant amount of water and energy, and the crops used to produce it may displace food crops or natural habitats.

Is there a Jeep Wrangler E85 Conversion Kit?

Some companies offer E85 conversion kits for vehicles, including Jeep Wrangler. However, it is essential to note that installing an E85 conversion kit on your Jeep Wrangler may not be straightforward and could potentially video the vehicle’s warranty.

In general, E85 conversion kits for vehicles involve installing a new fuel system that can handle the higher ethanol content of E85. This typically includes upgrading the fuel lines, injectors, and other components of the fuel systems. Additionally, the engine control unit (ECU) may need to be reprogrammed to optimize the vehicle’s performance on E85.

It is essential to do your research and choose a reputable company that specializes in E85 conversions for vehicles. You should also check with your Jeep dealer to see if installing an E85 conversion kit will void your vehicle’s warranty.

Remember that even with an E85 conversion kit, your vehicle’s fuel economy may still be lower when using E85 compared to gasoline, and the availability of E85 may still be limited in your area. It is necessary to weigh the potential benefits and drawbacks of using E85 in your Jeep Wrangler before investing in an E85 conversion kit.


Can you put E85 in a Jeep Wrangler? Yes, you can put E85 in a Jeep Wrangler if your vehicle is compatible, but there are several factors you should consider before doing so. You all need to think about your vehicle’s fuel economy and power output, the availability of E85 in your area, and the other factors mentioned in this article.
