How To Increase Ethanol In E85

Are you looking to increase the ethanol content in your E85 fuel? Whether you’re a car enthusiast looking for better performance or an environmentally-conscious driver seeking cleaner burning fuel, understanding how to increase ethanol levels in E85 can be beneficial.

E85 is a blend of gasoline and ethanol that contains up to 85% ethanol, making it a popular choice for fuel-efficient vehicles. However, the actual ethanol content in E85 can vary, and knowing how to increase it can help you get the most out of your fuel.

In this article, we will explore the factors that affect ethanol content in E85 and provide tips on how to increase it. From using higher ethanol blends to sourcing ethanol from different suppliers, we will examine different production processes and techniques that can help you achieve your desired ethanol content in E85.

With this knowledge, you can take control of your fuel efficiency and reduce your carbon footprint. So, let’s dive into the world of E85 and learn how to increase ethanol levels in your fuel.

Understanding the Benefits of E85

You’re missing out on the incredible benefits of E85 if you’re not using it in your vehicle! E85 is a blend of gasoline and ethanol, with the latter being a renewable fuel source made from plant materials.

E85 has a higher octane rating than regular gasoline, meaning it can provide better performance for your car. Additionally, ethanol burns cleaner than gasoline, reducing harmful emissions that can negatively impact the environment and your health.

A benefits analysis of E85 reveals that it can also save you money in the long run. While E85 may have a slightly lower fuel efficiency than gasoline, it is often priced lower at the pump, making up for the difference in mileage. Plus, the use of ethanol in fuel helps reduce our reliance on foreign oil, boosting energy security for our country.

So, not only can using E85 benefit your car’s performance, it can also positively impact our environment and economy.

Factors Affecting Ethanol Content in E85

Factors such as the sourcing of raw materials and the distillation process can impact the final composition of E85 fuel. One of the most important factors affecting the ethanol content of E85 is ethanol purity. The ethanol used in E85 is usually sourced from corn, but the purity of the ethanol can vary depending on the method of production and other factors. The higher the purity of the ethanol, the higher the percentage of ethanol in the E85 fuel.

Another factor that can affect the ethanol content of E85 is fuel storage. Ethanol is hygroscopic, which means it can absorb water from the air. When ethanol absorbs water, it can decrease the ethanol content of E85 and also cause other problems such as corrosion in fuel systems. To prevent this, E85 fuel must be stored properly in tanks that are specifically designed for ethanol fuel.

Proper storage can help maintain the ethanol content of E85 and ensure that it performs optimally.

Using Higher Ethanol Blends

Using higher ethanol blends can lead to improved engine performance and fuel efficiency. Blending techniques are used to increase the ethanol content in E85 by mixing it with higher concentrations of ethanol. The blending process is carefully controlled to ensure that the resulting fuel meets the required specifications for E85.

Blending techniques can also be used to improve fuel efficiency. Higher ethanol blends burn more cleanly than gasoline, resulting in fewer emissions and less pollution. In addition, ethanol has a higher octane rating than gasoline, which means that it can be used to increase the power output of an engine.

By using higher ethanol blends, you can improve the performance of your engine while reducing your environmental impact.

Different Production Processes

Have you ever considered the various processes for producing ethanol? Ethanol extraction and fermentation techniques are two common methods used to create this renewable fuel.

Ethanol extraction involves the use of chemical solvents to separate the ethanol from other compounds in the raw material. This process is generally used for cellulosic feedstocks, such as agricultural waste and forestry residues.

On the other hand, fermentation techniques use microorganisms to convert sugars into ethanol. This process is typically used for corn, sugarcane, and other sugar-rich crops. There are several fermentation techniques, including batch and continuous processes.

Each method has its own benefits and drawbacks, such as efficiency and cost-effectiveness. Understanding the different production processes for ethanol can help you make informed decisions about increasing ethanol content in E85.

Sourcing Ethanol from Different Suppliers

When you’re looking to source ethanol from different suppliers, it’s important to consider the variety of options available to you. Ethanol quality is a crucial factor to consider when selecting a supplier. You want to ensure that the ethanol you purchase meets the required standards and is suitable for blending with gasoline to produce E85.

Ethanol quality is usually measured by its purity level, moisture content, and acid content. It’s essential to purchase ethanol with high purity levels to ensure that your E85 blend is of the desired quality.

Blending techniques are also a vital consideration when sourcing ethanol from different suppliers. There are various blending techniques that suppliers use to produce ethanol, and each technique has its advantages and disadvantages. Some suppliers use dry milling, while others use wet milling to produce ethanol.

You need to research and understand the different blending techniques used by various suppliers to make an informed decision. Choosing the right blending technique will help you produce high-quality E85 that meets the desired specifications.


In conclusion, increasing the ethanol content in E85 can offer numerous benefits, such as lower emissions and cost savings. However, achieving a higher ethanol content requires careful consideration of various factors.

One way to increase ethanol in E85 is to use higher ethanol blends, such as E90 or E98. Additionally, choosing the right production process and sourcing ethanol from reputable suppliers can also impact the final ethanol content.

With proper planning and implementation, achieving a higher ethanol content in E85 can be a feasible and worthwhile endeavor.
