What Is Flex Fuel E85

If you’re looking for a fuel option that offers you more control over your car’s performance, then E85 might be the answer. E85, also known as flex fuel, is a blend of gasoline and ethanol that can be used in flexible-fuel vehicles (FFVs) and some traditional gasoline engines.

But what exactly is E85, and how does it compare to gasoline? In this article, we’ll explore the basics of E85 and help you decide if it’s right for your car.

First, let’s understand what E85 is. The ‘E’in E85 stands for ethanol, which is a renewable fuel made from crops such as corn and sugarcane. The number ’85’indicates that the fuel contains 85% ethanol and 15% gasoline. This blend is different from regular gasoline, which typically contains no more than 10% ethanol.

E85 is considered a biofuel because it’s made from renewable resources, and it produces fewer emissions than gasoline. However, it’s important to note that not all vehicles can use E85, so it’s crucial to understand if your car is compatible before making the switch.

Understanding the Basics of E85

If you’re looking to fuel up with E85, it’s important to understand that it’s a blend of 85% ethanol and 15% gasoline. This type of fuel is predominately made from corn, but can also be made from other sources such as sugarcane, switchgrass, and even waste materials like corn stalks.

Compared to regular gasoline, E85 has a higher octane rating, which means it can withstand higher compression ratios before detonating. This makes it a great fuel for high-performance vehicles.

One of the biggest advantages of E85 is its environmental impact. Ethanol is a renewable resource, meaning it can be produced indefinitely without depleting the Earth’s natural resources. Additionally, ethanol has a lower carbon footprint than gasoline, meaning it releases fewer greenhouse gases into the atmosphere.

However, there are also some disadvantages to using E85, such as its lower energy density compared to gasoline, which means you’ll need more fuel to go the same distance. Additionally, E85 is not as widely available as gasoline, so it may not be a practical option for everyone.

Comparing E85 to Gasoline

When you compare E85 to gasoline, you’ll find that E85 typically has a higher octane rating. This means that E85 can improve engine performance and power, especially in high-performance vehicles. However, E85 also has a lower energy density than gasoline, meaning it takes more fuel to achieve the same amount of power. This can lead to lower fuel efficiency and shorter driving range.

When it comes to the environmental impact comparison, E85 has the potential to be a more sustainable fuel option. E85 is made from domestically sourced renewable resources, such as corn or sugarcane, while gasoline is made from nonrenewable fossil fuels. Additionally, E85 produces fewer greenhouse gas emissions than gasoline, which contributes to improving air quality and reducing the impact of climate change.

However, the production of E85 also requires large amounts of water and energy, so it’s important to consider the full lifecycle impact of the fuel.

Is E85 Right for Your Car?

Considering whether E85 is a suitable option for your vehicle can depend on various factors. One of the most important factors is cost comparison. While E85 is typically cheaper than gasoline, it also has lower fuel efficiency. This means that you may end up spending more on fuel overall, even if the cost per gallon is lower.

It’s important to do the math and figure out if the potential savings in fuel costs outweigh the decreased fuel efficiency of E85.

Another factor to consider when deciding if E85 is right for your car is the environmental impact. E85 is often touted as a more environmentally friendly fuel than gasoline because it produces fewer emissions. However, the production of ethanol, which is the primary component of E85, requires a significant amount of resources and energy.

Additionally, the increased demand for corn (which is used to make ethanol) can lead to issues with food supply and prices. Ultimately, the decision to use E85 should be based on a careful consideration of both the economic and environmental factors.

Finding E85 Fueling Stations

Looking to fill up with E85? Check out this guide to find fueling stations near you!

To find E85 fueling stations, simply use a website or app that specializes in locating alternative fuel stations. These resources can easily be found with a quick online search. Once you’ve found a station near you, be sure to check the pump to ensure that it dispenses E85 fuel specifically, as many stations offer multiple types of fuel.

When it comes to fuel economy, E85 may not be the best choice for every driver. While it can offer significant cost savings, the fuel has a lower energy content than gasoline, which can lead to decreased fuel efficiency. However, E85 does have a positive environmental impact, as it produces fewer emissions compared to gasoline.

Before deciding whether or not to switch to E85, it’s important to consider your driving habits and consult with a trusted mechanic or fuel expert to ensure that it’s the right choice for your vehicle.


Congratulations! You now have a solid understanding of flex fuel E85. This alternative fuel is a blend of gasoline and ethanol, with a higher percentage of ethanol than traditional gasoline. E85 can offer benefits such as lower emissions and potentially lower fuel costs, but it’s important to consider whether your vehicle is compatible and whether it’s available in your area.

When comparing E85 to gasoline, it’s important to note that E85 has a lower energy density, which can result in lower fuel efficiency and potentially lower performance in some vehicles. However, E85 can also offer higher octane ratings and a cleaner burn. It’s important to weigh the pros and cons and determine if E85 is the right choice for your specific vehicle and driving habits.

If you do decide to try E85, be sure to locate fueling stations in your area that offer the blend. Not all gas stations carry E85, so it may require some research and planning.

Overall, E85 can offer a viable alternative to traditional gasoline, but it’s important to do your research and make an informed decision.
