Does E85 Outperform 93 Octane Fuel in Power?
Many car enthusiasts are always on the hunt for ways to squeeze more power out of their engines. One question that often arises in this pursuit is whether E85, a fuel blend containing 85% ethanol and 15% gasoline, can deliver more oomph than the commonly used 93 octane fuel. So, let’s dive into the ring and see which fuel comes out as the heavyweight champion of power!
Unleashing the Ethanol Beast
E85: A Boost for Power?
When it comes to power, E85 has its advantages. The higher octane rating of E85 (which is around 105 to 108) compared to 93 octane fuel means that it can be compressed more before spontaneously combusting. This increased resistance to knocking allows for higher compression ratios and more aggressive timing, resulting in increased power output.
Flex Fuel Vehicles: The Key to E85 Dominance
Flex fuel vehicles (FFVs) are designed to run on a variety of fuel blends, including E85. These vehicles have specific engine calibrations that optimize performance when running on E85. FFVs typically have larger fuel injectors, modified fuel lines, and other components, allowing them to take full advantage of the benefits of E85. This means that if you want to truly unleash the power potential of E85, driving an FFV is the way to go.
The Blend Game: Finding the Sweet Spot
One factor to consider with E85 is the actual ethanol content in the fuel. E85 can vary in composition, with ethanol levels ranging from 51% to 83%. Ethanol contains less energy per unit volume than gasoline, which means a larger volume of E85 is required to match the energy content of gasoline. Depending on the ethanol content and engine calibration, power gains from E85 can vary.
The 93 Octane Contender
The Tried and True
93 octane fuel has been the go-to choice for most performance enthusiasts. It offers a good balance of power and cost, making it widely available at gas stations. While it may not provide the same knock resistance as E85, many modern engines can still extract impressive power from it.
Not Just About the Octane
Power gains from fuel aren’t solely determined by the octane rating. Factors such as engine design, turbocharging, and tuning also play a significant role. Some engines may be more sensitive to octane levels, while others may not see significant gains from switching to higher-octane fuels.
The Power Struggle Continues
Ultimately, whether E85 or 93 octane fuel makes more power depends on various variables. If you’re driving an FFV with a high ethanol concentration, E85 has the potential to deliver impressive power gains. However, if you’re running a non-flex fuel vehicle or have limited access to E85, 93 octane can still provide satisfying performance.
The Verdict? It’s up to You!
Both E85 and 93 octane fuel have their advantages and can deliver respectable power gains. If you own a flex fuel vehicle and have access to high-concentration E85, it’s worth exploring the potential of E85 to unlock additional horsepower. On the other hand, if you’re working with a non-flex fuel vehicle, or E85 availability is limited in your area, sticking with good old 93 octane fuel will still allow you to enjoy spirited driving.
Remember, the best fuel for your engine depends on a multitude of factors, so choose wisely and let your inner speed demon ride!
Frequently Asked Questions about E85 Fuel
Does E85 mess up your car

So, before switching to E85, make sure your vehicle supports it. It’s always a good idea to consult your car’s manual or talk to a qualified mechanic to ensure compatibility.
How much horsepower does E85 add to a Chevrolet SS
The amount of horsepower E85 can add to a Chevrolet SS depends on various factors such as the car’s engine, modifications, and tuning. On average, E85 can provide a power increase of up to 10-15% compared to regular gasoline. However, it’s important to note that individual results may vary.
How much horsepower does a 91 tune add
A 91 tune can offer a noticeable boost in horsepower. Typically, a well-tuned 91 octane fuel map can add around 15-20 horsepower to your car. However, it’s worth mentioning that the exact power gains can vary depending on the specific car, its modifications, and other factors.
Why does E85 pump so slow
You might have noticed that E85 pumps tend to deliver fuel at a slower rate compared to regular gasoline pumps. This is because E85 has a higher ethanol content, which requires a larger volume of fuel to achieve the same energy content as gasoline. Therefore, the slower fueling rate allows the pump to deliver the correct amount of fuel.
Does E85 give you more horsepower
Yes, E85 can give you more horsepower in certain situations. Due to its higher octane rating and cooling properties, E85 allows for more aggressive timing and boost levels, resulting in increased power output.
