Ethanol-free premium fuel, also known as pure gas or pure gasoline, is a type of fuel that does not contain ethanol, a common additive in most gasoline sold today. While ethanol is often blended with gasoline to help reduce emissions and improve octane ratings, some consumers and industries prefer ethanol-free options for various reasons. This article delves into the benefits of ethanol-free premium fuel, explores the types available, and identifies where to find them.
The Rise of Ethanol-Blended Fuels
Ethanol, primarily derived from corn in the United States, has been used as a gasoline additive for several decades. It is an alcohol that can be mixed with gasoline to create a cleaner-burning fuel. The most common blend is E10, which contains 10% ethanol and 90% gasoline. Higher blends, such as E15 and E85, contain more ethanol and are designed for specific vehicles known as Flex-Fuel Vehicles (FFVs).
The push for ethanol-blended fuels has been driven by environmental concerns, energy independence, and agricultural interests. Ethanol can reduce greenhouse gas emissions and decrease reliance on fossil fuels. Additionally, it provides an important market for corn producers.
Drawbacks of Ethanol-Blended Fuels
Despite its benefits, ethanol-blended fuel has its drawbacks. Ethanol is hygroscopic, meaning it absorbs water from the air. This can lead to issues such as phase separation, where the water and ethanol mixture separates from the gasoline, potentially causing engine problems. Ethanol also has a lower energy content than gasoline, which can result in reduced fuel economy.
For some engines, particularly older models and small engines like those in lawnmowers, boats, and classic cars, ethanol can cause damage. These engines may not be designed to handle the corrosive effects of ethanol, leading to deterioration of fuel lines, gaskets, and other components.
Benefits of Ethanol-Free Premium Fuel
1.Longevity and Stability
Ethanol-free fuel is more stable and has a longer shelf life compared to ethanol-blended fuel. This makes it ideal for engines that are not used frequently, such as boats, motorcycles, and seasonal equipment. The lack of ethanol reduces the risk of water absorption and phase separation, ensuring the fuel remains effective over time.
2.Improved Fuel Economy
Since ethanol has a lower energy content than gasoline, ethanol-free fuel can provide better fuel economy. Drivers may notice an increase in miles per gallon (MPG) when using ethanol-free premium fuel, which can offset its typically higher cost.
3.Engine Protection
Ethanol-free fuel is less corrosive and less likely to cause damage to engine components. This is particularly important for older vehicles and small engines not designed to run on ethanol-blended fuels. Using ethanol-free fuel can extend the life of these engines and reduce maintenance costs.
Types of Ethanol-Free Premium Fuels
1.Recreational Fuel (REC-90)
Recreational fuel, commonly referred to as REC-90, is a type of ethanol-free gasoline designed for use in boats, jet skis, and other marine equipment. It is also suitable for motorcycles, ATVs, and small engines. REC-90 typically has an octane rating of 90, providing good performance without the drawbacks of ethanol.
2.Clear Gasoline
Clear gasoline, or clear gas, is a term used to describe ethanol-free gasoline that is often used in aviation, agriculture, and certain high-performance vehicles. It is known for its high purity and consistency, making it a preferred choice for engines requiring reliable and stable fuel.
3.Aviation Gasoline (AVGAS)
Aviation gasoline, or AVGAS, is a specialized type of gasoline used in piston-engine aircraft. AVGAS is ethanol-free and has a high octane rating, typically 100 or more. While not commonly used in automobiles, AVGAS demonstrates the importance of ethanol-free fuel in applications where performance and reliability are critical.

Finding Ethanol-Free Premium Fuel
Gas Stations and Retailers
Many gas stations across the United States offer ethanol-free premium fuel. Websites like pure-gas.org provide databases of gas stations that sell ethanol-free gasoline, making it easier for consumers to find a nearby source. These fuels are often labeled as “ethanol-free” or “clear gasoline.”
Marinas and Recreational Facilities
Marinas and recreational facilities frequently offer ethanol-free fuel for boats and watercraft. Since ethanol can cause significant damage to marine engines, these facilities often stock REC-90 or similar fuels to meet the needs of boaters.
Specialty Fuel Distributors
Specialty fuel distributors cater to industries requiring ethanol-free fuel, such as aviation, agriculture, and motorsports. These distributors provide high-quality ethanol-free gasoline in bulk quantities, ensuring consistent supply for commercial and recreational use.
Considerations When Using Ethanol-Free Fuel
Cost
Ethanol-free premium fuel is generally more expensive than ethanol-blended gasoline. The higher cost is due to the additional refining required to produce pure gasoline and the lower demand compared to E10 or other blends. Consumers should weigh the benefits of improved performance and engine protection against the increased expense.
Availability
Ethanol-free fuel is not as widely available as ethanol-blended gasoline. While many gas stations and marinas offer ethanol-free options, it may not be available in all areas. Checking online resources and planning ahead can help ensure access to ethanol-free fuel when needed.
Environmental Impact
While ethanol-free fuel can offer better performance and engine protection, it does not have the same environmental benefits as ethanol-blended fuels. Ethanol is renewable and can reduce greenhouse gas emissions. Consumers should consider the environmental impact of their fuel choices and balance it with their specific needs.
Case Studies and Testimonials
Classic Car Enthusiasts
Many classic car owners prefer ethanol-free fuel to protect their valuable engines. Classic car enthusiasts often report smoother performance and fewer engine problems when using ethanol-free gasoline. For example, a 1965 Ford Mustang owner might choose ethanol-free fuel to prevent damage to the car’s carburetor and fuel system.
Boating Community
Boaters, particularly those with older or high-performance engines, often choose ethanol-free fuel to avoid the risks associated with ethanol. Marine engines are susceptible to water absorption and phase separation, making ethanol-free fuel a safer option. A boat owner might opt for REC-90 to ensure their engine remains in good condition during the boating season.
Small Engine Users
Owners of lawnmowers, chainsaws, and other small equipment often prefer ethanol-free fuel to prevent damage and ensure reliable operation. Ethanol can cause significant issues in small engines, leading to costly repairs and downtime. A landscaper might use ethanol-free gasoline to keep their equipment running smoothly throughout the season.
Technological Advances and Future Trends
Improved Ethanol-Blended Fuels
Research and development are ongoing to improve the performance of ethanol-blended fuels. Advances in additives and refining processes aim to reduce the drawbacks of ethanol, making it more compatible with a wider range of engines. These improvements could make ethanol-blended fuels a more viable option for more consumers.
Alternative Fuels
The search for alternative fuels continues as the automotive and energy industries seek to reduce reliance on fossil fuels. Biofuels, synthetic fuels, and hydrogen are all potential alternatives that could provide the benefits of ethanol-free gasoline without the environmental impact. These alternatives may become more prevalent in the coming years, offering new options for consumers.
Regulatory Changes
Government regulations play a significant role in the fuel industry. Changes in environmental policies, agricultural subsidies, and fuel standards can impact the availability and composition of fuels. Keeping an eye on regulatory developments can help consumers stay informed about their fuel choices and potential changes in the market.
Conclusion
Ethanol-free premium fuel offers several benefits, including improved engine performance, longevity, and protection against corrosion. While it is more expensive and less widely available than ethanol-blended fuels, it remains a preferred choice for certain engines and applications. Whether for classic cars, boats, or small engines, ethanol-free fuel provides a reliable and stable option that meets the needs of discerning consumers.
Understanding the types of ethanol-free premium fuel, such as REC-90 and AVGAS, can help consumers make informed decisions about their fuel choices. With the right information and resources, finding and using ethanol-free premium fuel can ensure optimal performance and longevity for a wide range of engines.
