E85 vs. Gasoline: Pros and Cons | Comprehensive Comparison

When it comes to choosing the right fuel for your vehicle, the decision between E85 (ethanol) and gasoline is crucial. Each option has its own set of advantages and disadvantages that can impact your vehicle's performance, fuel economy, and environmental footprint. In this comprehensive guide, we'll delve into the key differences between E85 and gasoline, helping you make an informed choice.
​

1. Energy Production
Gasoline:Gasoline is known for its high energy density, producing more energy per gallon than ethanol. This results in superior horsepower performance for vehicles running on gasoline.
E85: E85 is a blend of 85% ethanol and 15% gasoline. However, it has approximately 33% less energy content compared to gasoline. Consequently, vehicles running on E85 may experience reduced horsepower.

2. Fuel Efficiency
Gasoline: Gasoline generally offers better fuel efficiency compared to E85. Vehicles powered by gasoline tend to cover more miles per gallon, making it an ideal choice for those seeking maximum fuel economy.

E85: Ethanol requires more energy to burn, which means that vehicles running on E85 will have lower fuel efficiency. You can expect anywhere from 15% to 27% fewer miles per gallon compared to gasoline.

3. Engine/Fuel System Protection
Gasoline: Gasoline provides better protection for your vehicle's engine and fuel system. It is less prone to issues like fuel separation and water contamination, which can be problematic with ethanol. Additionally, gasoline is less corrosive to fuel system components.
E85: Ethanol is hygroscopic, meaning it absorbs water. This can lead to fuel system issues if the vehicle is left unused for extended periods. Ethanol's corrosive nature can also harm plastic and metal components over time.

4. CostGasoline: Gasoline prices can vary, but it is generally more widely available. The cost of gasoline may be higher in some regions, but it often offers better fuel efficiency, potentially offsetting the price difference.
E85: E85 is often cheaper than gasoline, especially in areas where it is produced. However, the cost advantage should be weighed against reduced fuel efficiency and potential long-term vehicle maintenance costs.

What is Ethanol (E85)?
Ethanol is a biofuel derived from fermented plants, such as corn, sugarcane, algae, or manure. As a renewable energy source, ethanol production relies on living organisms. Despite the energy required for production, ethanol is known for its cleaner burn, which can benefit the environment. The most common ethanol blend is E85, containing 85% ethanol and 15% gasoline.

What is Gasoline?
Gasoline is produced from petroleum liquids and crude oil. It undergoes refinement and may have additives like ethanol. Gasoline is available in various grades, with higher octane ratings commanding higher prices. In the United States, gasoline typically contains 10% ethanol.

Ethanol Pros
1. Lowered Greenhouse Gases
Ethanol reduces emissions by up to 30% per mile driven, contributing positively to environmental efforts. It is made from raw materials that are safe for the environment, reducing concerns about contamination.

2. Renewable Energy Source
Ethanol relies on plant materials, making it a renewable and sustainable energy source. It can be produced from various plants, ensuring a consistent supply.
​
3. Created by Numerous Raw Materials
While corn is a common source of ethanol in the U.S., other countries use sugarcane, algae, or cellulosic materials. This versatility ensures a stable supply chain.

Ethanol Cons1. Fluctuating Prices
Ethanol prices vary by location, with the greatest savings in regions of production, such as the Midwest. However, savings may be limited in areas with transportation costs.

2. Lacking Infrastructure
Not all fueling stations offer ethanol, leading to accessibility issues. Additionally, ethanol production requires ample farm space, potentially limiting production.
3. Damage to Vehicles
Ethanol's water-absorbing properties can lead to issues in vehicles, including dissolving rubber and plastic components. This can result in expensive repairs.

Gasoline Pros1. Better Fuel Economy
Gasoline-powered vehicles typically achieve up to 27% better fuel economy than those running on ethanol. This can lead to long-term cost savings.
2. Easier to Find
Gasoline is widely available at fueling stations across the country, making it a convenient choice for drivers.
3. Better for the Vehicle
Gasoline provides adequate lubrication for vehicle components, reducing the risk of engine and fuel system damage.
Gasoline Cons1. Bad for the Environment
Gasoline-powered vehicles contribute significantly to CO2 emissions, which have detrimental effects on the environment, including climate change and rising sea levels.
2. Foreign Fuel Sources
A significant portion of gasoline used in the United States is imported, potentially leading to economic vulnerabilities due to fluctuating oil prices and dependence on foreign sources.

Ethanol or Gasoline: What’s the Right Choice?
The decision between ethanol (E85) and gasoline depends on your priorities and location. Ethanol offers environmental benefits but may be less convenient due to availability and potential vehicle-related issues. Gasoline provides better fuel economy and widespread accessibility but comes with environmental drawbacks. Consider your values, driving habits, and regional factors when making your choice.
​
Does E85 Burn Faster?
Yes, E85 burns faster due to its lower energy content compared to gasoline. Vehicles running on E85 use more fuel and produce fewer miles per gallon.
