Why E85

If you’re looking to gain more control over your fuel consumption and reduce your carbon footprint, you may want to consider switching to E85. E85 is a blend of gasoline and ethanol that contains up to 85% ethanol. This renewable fuel is becoming increasingly popular among environmentally conscious drivers who want to reduce their dependence on fossil fuels.

One of the main reasons why E85 is gaining popularity is its composition. Ethanol is a renewable resource that can be produced from a variety of feedstocks, including corn, sugarcane, and switchgrass. When blended with gasoline, it reduces the amount of petroleum in the fuel, which in turn reduces greenhouse gas emissions.

This means that using E85 can help you reduce your carbon footprint and contribute to a cleaner environment. In this article, we’ll explore the benefits of using E85, its compatibility with vehicles, and potential drawbacks to help you make an informed decision about whether this fuel is right for you.

Understanding the Composition of E85

Let’s break down what’s in E85 and why it’s different from regular gasoline. E85 is a blend of gasoline and up to 85% ethanol, a type of alcohol produced from corn, sugarcane, or other crops. The exact amount of ethanol in E85 can vary depending on factors such as the season, location, and availability of ethanol. However, it typically contains around 70-85% ethanol content and 15-30% gasoline.

One of the major advantages of using E85 is its high octane rating. The octane rating is a measure of a fuel’s ability to resist ‘knocking,’ a type of uncontrolled combustion that can damage the engine. E85 has an octane rating of around 100-105, which is higher than most regular gasoline types. Regular gasoline typically has an octane rating of 87-93. This means that E85 can provide better performance and efficiency for high-performance engines, as well as reduce emissions and engine wear.

Benefits of Using E85

You’ll feel the power surge through your engine and notice a cleaner burn when you switch to using E85, which can result in better performance and lower emissions.

E85 is a blend of 85% ethanol and 15% gasoline, which makes it a more environmentally friendly fuel option. Ethanol is a renewable resource that’s made from corn, sugarcane, and other plant materials, making it a sustainable alternative to traditional gasoline.

Aside from its environmental impact, E85 can also be cost-effective for drivers. While the initial cost of converting a vehicle to run on E85 may be higher, the price of E85 is typically lower than traditional gasoline. Additionally, some states offer tax incentives for using E85, making it an even more attractive option for drivers looking to save money.

By choosing E85, you can not only improve the performance of your vehicle but also do your part in reducing your carbon footprint and saving money in the long run.

Compatibility with Vehicles

Many vehicles on the market today are compatible with E85 fuel due to their flex-fuel capabilities. This means they can run on a blend of up to 85% ethanol and 15% gasoline, providing a more sustainable fuel alternative.

In fact, according to the Department of Energy, there are currently over 4 million flex-fuel vehicles on the road in the United States. If you’re considering using E85 in your vehicle, it’s important to note that it may require some vehicle modifications.

Because ethanol has different properties than gasoline, it can affect engine performance. However, many newer vehicles are designed to handle E85 without any modifications. It’s recommended to check with your vehicle manufacturer to see if your vehicle is compatible and what modifications may be needed before using E85 as a fuel alternative.

Potential Drawbacks

If you’re considering using e85 as a fuel source, it’s important to be aware of some potential drawbacks.

One of the main concerns is reduced fuel efficiency, which can lead to more frequent refueling and higher costs in the long run.

Additionally, e85 availability is still limited in many areas, so it may not be a viable option for all drivers.

It’s important to weigh these factors against the potential benefits before making a decision.

Reduced Fuel Efficiency

Don’t expect better mileage with E85, as it typically reduces fuel efficiency by up to 30%. This means that you will need to fill up your tank more often, resulting in a heavier strain on your wallet.

In addition, the reduced fuel efficiency also means that you will be emitting more greenhouse gases into the environment, leaving you with a greater carbon footprint.

The impact on engine performance is also something to consider when using E85. While some vehicles are designed to run on E85, others may experience engine problems and reduced power output. It’s important to check with your manufacturer to see if your vehicle is compatible with E85.

Even if your vehicle is compatible, you should still do a cost comparison to see if the potential savings from using E85 outweigh the reduced fuel efficiency and potential engine problems.

Limited Availability

Unfortunately, you may have difficulty finding E85 at your local gas station due to its limited availability. E85 is a relatively new fuel type and not all gas stations are equipped to handle it.

According to the U.S. Department of Energy, there are currently only about 4,500 gas stations that offer E85 in the United States. This is a small fraction of the over 150,000 gas stations in the country.

Challenges of finding E85 include the fact that it is not yet widely distributed and the infrastructure needed to produce and distribute it is still being developed. Additionally, the demand for E85 is not as high as traditional gasoline, which also contributes to its limited availability.

Despite these challenges, there are alternatives for those who are committed to using alternative fuels. For example, electric cars are becoming more popular and charging stations are becoming more prevalent. There are also other alternative fuels, such as biodiesel and hydrogen, that may have more widespread availability in the future.


In conclusion, you now understand what E85 is and its composition. The blend of 85% ethanol and 15% gasoline offers benefits such as higher octane rating, lower emissions, and the potential for increased horsepower.

Using E85 can also be compatible with Flex Fuel vehicles and some modified vehicles. However, it’s important to note that there may be potential drawbacks such as decreased fuel efficiency and limited availability.

When deciding whether or not to use E85, it’s important to weigh the benefits and drawbacks and consider factors such as availability and compatibility with your vehicle. Ultimately, the decision to use E85 should be based on individual circumstances and priorities.

By understanding the composition and benefits of E85, you can make an informed decision about whether or not it’s right for you.
