Why Is E85 Better For Racing

If you’re looking to gain an edge in racing, you may want to consider switching to E85 fuel. E85, a blend of 85% ethanol and 15% gasoline, has become increasingly popular in racing circles due to its higher octane rating and cooler burning temperature.

But that’s not all – E85 also offers environmental benefits, cost savings, and greater availability and accessibility than other racing fuels.

First and foremost, E85 boasts an octane rating of around 105, which is significantly higher than that of traditional gasoline (which typically has an octane rating of around 87-93). This higher octane rating allows for greater compression ratios and more aggressive ignition timing, which can lead to increased horsepower and torque.

Plus, E85’s cooler burning temperature helps to prevent engine knocking and other issues that can occur when running on lower-octane fuels.

Higher Octane Rating

You’ll find that e85 is a better option for racing due to its higher octane rating, which can provide significant benefits for engines.

The octane rating is a measure of a fuel’s ability to resist knocking or detonation, which can cause damage to the engine.

E85 has an octane rating of around 105, which is significantly higher than regular gasoline, which typically has an octane rating of around 87-93.

This means that e85 can withstand higher compression ratios and temperatures, allowing engines to produce more power and perform better.

The impact on performance is significant. With a higher octane rating, e85 can allow for more advanced ignition timing, which can result in more complete combustion, better fuel efficiency, and increased power output.

Additionally, e85 has a cooling effect on the intake charge, which can reduce the risk of engine knock and allow for even higher compression ratios.

Overall, e85 provides a range of benefits for racing engines, making it an excellent choice for those who want to maximize their performance on the track.

Cooler Burning Temperature

With its ability to burn at a cooler temperature, E85 provides a competitive advantage for racers looking to boost their performance. This is because the cooler burning temperature of E85 allows the engine to operate at a higher compression ratio, which results in improved performance.

In fact, studies have shown that E85 can increase horsepower by up to 5-10% when compared to traditional gasoline. But the advantages of E85 don’t stop there. The cooler burning temperature also leads to improved engine durability.

This is because the cooler temperatures help reduce engine knock, which can cause serious damage to an engine over time. In addition, E85’s higher oxygen content can help keep the engine cleaner, reducing the amount of carbon buildup that can lead to engine wear and tear.

All of this means that using E85 can help racers get the most out of their engines while also ensuring that they last longer and require less maintenance in the long run.

Environmental Benefits

If you’re looking to reduce your carbon footprint, using E85 fuel in your vehicle can be a great option. E85, also known as flex fuel, is a renewable source of fuel that is made up of 85% ethanol and 15% gasoline.

The ethanol in E85 is derived from corn or other renewable sources, and it produces fewer harmful emissions than traditional gasoline. In addition to being a renewable fuel source, E85 also produces fewer carbon emissions than traditional gasoline. This is great news for the environment, as reducing carbon emissions is an important step in fighting climate change.

So, not only is E85 better for racing because of its cooler-burning temperature, but it is also a more environmentally friendly option for those who are looking to reduce their carbon footprint.

Cost Savings

Saving money on fuel costs is a major concern for many drivers, and using E85 in your vehicle can be a smart financial decision. While E85 is typically cheaper than gasoline, it also has a lower energy content, which means your vehicle will consume more fuel to travel the same distance. However, the lower cost of E85 can still result in significant savings over time, especially for drivers who cover a lot of miles in their vehicles.

In addition to cost savings, using E85 can also result in performance gains. Because E85 has a higher octane rating than gasoline, it can support higher compression ratios and boost pressure, which can result in increased power output and better throttle response. While the exact performance gains will depend on your specific vehicle and driving conditions, using E85 can provide a noticeable improvement in overall driving experience.

Additionally, because E85 is a renewable fuel source, it can help reduce our dependence on fossil fuels and promote sustainable driving practices.

Availability and Accessibility

Availability and accessibility of E85 is crucial for drivers who want to use this renewable fuel source in their vehicles. The supply chain for E85 is not as established as traditional gasoline, which means that the availability of E85 varies depending on the region. However, the good news is that the number of E85 fueling stations in the US has been increasing over the years.

In 2018, there were over 4,000 E85 fueling stations across the country, up from just over 2,000 in 2012. The accessibility of E85 has also improved, as more gas stations are now offering the fuel alongside traditional gasoline. This is especially true in regions that are more agriculture-focused, as E85 is made from corn.

However, there are still areas where E85 is not readily available, which can be a challenge for drivers who want to use this fuel. In these cases, drivers may need to plan their routes carefully to ensure they can refuel with E85 along the way.


As a racer, you need to optimize your vehicle’s performance to gain a competitive edge. Switching to E85 can help you achieve that goal. With its higher octane rating, cooler burning temperature, and cleaner emissions, E85 provides a superior fuel option for high-performance engines.

Moreover, its cost savings and availability make it a smart choice for any budget-conscious racer. So, if you want to take your racing game to the next level, consider making the switch to E85.

In conclusion, you now understand why E85 is better for racing than traditional gasoline. With a higher octane rating and cooler burning temperature, E85 provides optimal performance for high-performance engines. Furthermore, its environmental benefits, cost savings, and increased accessibility make it a more attractive option for racers.
