Whether you can put E85 in your Dodge Charger depends on if the vehicle is flex-fuel capable. Not every Charger can safely use this type of fuel.

Your Dodge Charger might be eligible to run on E85 if it is a flex-fuel model. If uncertain, one straightforward way to verify is by checking the inside of your fuel door or consulting your vehicle’s owner manual. Using E85 in a non-flex fuel vehicle can lead to significant damage to the engine and fuel system components. It is pertinent to ensure your vehicle’s compatibility before fueling with E85.

Some drivers have pursued E85 conversion kits for their vehicles, such as Dodge Challengers or Rams. A popular choice is the 5.7 Hemi E85 conversion kit. With such a kit, a car originally not designed for E85 use can safely handle this biofuel. Although E85 offers potential benefits like increased horsepower – a notable feature of the E85 Scat Pack – it’s not as simple as switching fuels. Conversion requires significant modifications and should be carried out by a professional to avoid risking damage to your vehicle.

Considering a Charger RT for E85 usage could be a possibility. However, similar to other Dodge models, only if the Charger RT is flex-fuel compatible can it utilize E85. Before taking any decisions, always make sure to validate the vehicle’s flex-fuel status. It’s crucial to remember that using E85 on non-flex fuel cars, even robust models like the 5.7 Hemi, can lead to severe damages, making it imperative to confirm whether your Dodge Charger is flex-fuel or not.

E85: The Core Components

Composition and Production of E85

E85 is a biofuel mixture, predominantly comprised of ethanol (approximately 51% to 83%), the balance being traditional gasoline. Produced through the fermentation of sugars from crops such as corn or sugarcane, this high-octane fuel can provide notable performance benefits.

Pros and Cons of E85 Usage

E85 has a higher octane rating than regular gasoline, which can boost engine performance. It’s renewable, reduces reliance on fossil fuels, and can lower greenhouse gas emissions. Yet, it’s not all positive – E85 has a lower energy content per gallon than gasoline, leading to reduced fuel economy.

Equipped with powerful engines, ranging from V6 to V8 options, the Dodge Charger delivers an exhilarating driving experience. Superior handling, smooth ride quality, and aggressive acceleration underscore its performance credentials.

Fuel Options for Dodge Charger

Fuel TypeProsCons
Regular GasolineWidely available; Optimal fuel economyNon-renewable; Higher emissions
Premium GasolinePotential performance boostMore expensive; Non-renewable
E85Renewable; Lower emissions; Enhanced performanceLower fuel economy; Limited availability

Comparing Different Fuel Types

Each fuel type has its unique benefits and drawbacks. Regular gasoline is readily available and provides optimal fuel economy. Premium gasoline may offer a slight performance boost but is more expensive. E85, while renewable and offering performance benefits, suffers from limited availability and lower fuel economy.

Suitability of E85 for Dodge Charger

Certain models of the Dodge Charger, specifically the flex fuel vehicles (FFVs), can run on E85. In the following sections, we’ll delve deeper into this topic.

E85 Compatibility Across Dodge Charger Models

Flex Fuel Vehicles (FFVs): An Overview

Flex fuel vehicles are designed to run on more than one type of fuel, usually gasoline blended with either ethanol or methanol fuel. These vehicles have modified engines and fuel systems to accept the different fuel compositions.

Identifying FFV Models within the Dodge Charger Line-up

Check the fuel door or owner’s manual of your Dodge Charger to see if it’s a FFV. Typically, there will be a label or badge indicating this compatibility. Only these models should use E85.

The Mechanics of E85 in a Dodge Charger

Real-World Experiences with E85

Owners of Dodge Charger FFVs report a variety of experiences with E85. While some enjoy the performance enhancement, others notice a dip in fuel economy. Each driver’s experience will depend on the particular model, driving conditions, and personal driving style.

Performance and Fuel Economy Metrics

E85 can offer a higher octane rating, which may improve performance. On the flip side, since E85 contains less energy per gallon compared to gasoline, it may result in a decrease in fuel economy.

Conversion to E85: The Process

Hardware Modifications Required

Converting a non-FFV Dodge Charger to run on E85 is a technical process involving changes to the fuel system, including the fuel injectors and fuel pump, and updating the engine control unit (ECU) software.

Legal Implications and Warranty Concerns

Before considering a conversion, remember that modifications could void your vehicle’s warranty. They may also not be legal in certain jurisdictions. Always consult with a professional and research local laws before proceeding.

AreaNumber of E85 StationsAverage Price per Gallon

Distribution of E85 Fuel Stations

While E85 is available across the country, its distribution is uneven. The Midwest, where much of the corn for ethanol is grown, has the highest number of E85 stations.

E85 versus Regular Gasoline Costs

On average, E85 is less expensive per gallon than regular gasoline. However, given that E85 has a lower energy content and thus yields fewer miles per gallon, the overall cost per mile might be higher.

Environmental Impact of E85

E85’s Role in Greenhouse Gas Emission Reduction

E85 helps reduce the total greenhouse gas emissions, especially carbon dioxide, due to the lifecycle of ethanol. The crops used in ethanol production absorb CO2 as they grow, offsetting some of the emissions when the fuel is burned.

The Ecological Footprint of Ethanol Production

While E85 usage reduces fossil fuel dependence, the production process for ethanol involves considerable energy and water use, and can contribute to deforestation and soil erosion. Balancing these factors is key to assessing the overall environmental impact.

Caring for Your E85 Dodge Charger

Special Maintenance Requirements for FFVs

While FFVs like the Dodge Charger can run on E85 without any special maintenance, it’s always advisable to follow the manufacturer’s recommended maintenance schedule, ensuring the vehicle performs optimally.

Tips for Prolonging Vehicle Life

To maintain your E85-fueled Dodge Charger, it’s best to use high-quality fuel from reputable stations. Monitor your vehicle for any changes in performance, and if noted, have your vehicle checked by a professional promptly.
