Can you run E85 Flex Fuel in your 2011-2018 Ram 1500 5.7L

Are you a proud owner of a 2011-2018 Ram 1500 5.7L and intrigued by the idea of using E85 ethanol fuel? Perhaps you've heard about the benefits of flex fuel vehicles and are wondering if it's possible to make the switch. Well, the answer is a resounding "yes," and we're here to tell you how you can do it effortlessly with eFlexFuel's E85 conversion kits.

What Is E85 Ethanol Fuel?

Before diving into the benefits and the eFlexFuel solution, let's briefly explain what E85 ethanol fuel is. E85 is a blend of 85% ethanol and 15% gasoline. It's a renewable, high-octane fuel that's derived from sources like corn and sugarcane. E85 is known for its environmental advantages, as it produces fewer emissions than regular gasoline, making it an excellent choice for those who are eco-conscious.

The Flex Fuel Advantage

One of the best ways to embrace the world of E85 is by converting your vehicle into a flex fuel vehicle. With eFlexFuel's E85 conversion systems, this transition becomes seamless. But why should you consider it?

Cost Savings: E85 is often more affordable than regular gasoline, allowing you to save money at the pump. The eFlexFuel kit helps you take full advantage of these savings by ensuring your vehicle can efficiently run on E85.

More Horsepower: E85 has a higher octane rating than gasoline, which means it can lead to improved engine performance. When you install an eFlexFuel E85 kit, your 2011-2018 Ram 1500 5.7L will not only run on E85 but can also make more horsepower.

Environmental Benefits: As a flex fuel vehicle owner, you contribute to reducing greenhouse gas emissions, which is a win for the environment. E85 is renewable and can be produced domestically, further decreasing our dependence on foreign oil.
