Using ethanol-free gas in your lawn mower can be beneficial as it reduces the risk of damage to the engine, caused by ethanol attracting moisture and potentially leading to corrosion. Additionally, ethanol-free gas can provide more efficient combustion, improving the mower’s performance. However, it can be more expensive and less environmentally friendly than ethanol-blended fuels. Regular maintenance is also key, regardless of the fuel type used.
Places to Buy Ethanol-Free Gas
Local Gas Stations
Some local stations offer ethanol-free gas; these are often independently owned and cater to customers with specific fuel needs. Check with individual stations to confirm availability.
Marinas
Marinas often have ethanol-free gas, as boats typically require this fuel. It’s designed to prevent moisture-related issues associated with ethanol in marine environments.
Recreational Areas
Ethanol-free gas may be available near off-road vehicle parks as it is commonly used in ATVs and dirt bikes for better performance and engine longevity.
Specialty Fuel Shops
These stores specialize in various fuels, including ethanol-free options, catering to users with specific fuel requirements for their equipment.
Online Fuel Locators
Websites like pure-gas.org list locations that sell ethanol-free gasoline, providing an easy way to find nearby options.
Airport Fuel Depots
Some small airports sell ethanol-free aviation gasoline, but this fuel is not recommended for non-aviation engines due to different additives and regulations.
Agricultural Supply Stores
These stores sometimes offer ethanol-free gas as farming equipment and machinery often perform better with this fuel type.
Effects of Ethanol Fuel On Engines
Corrosion: Ethanol attracts water from the air, leading to water accumulation in the fuel system, which can cause corrosion in the fuel lines, carburetor, and engine.
Degradation of Plastic and Rubber Components: Ethanol can degrade certain plastics, rubber, and seals in the fuel system, leading to leaks and potential engine damage.
Decreased Fuel Efficiency: Ethanol has less energy content compared to gasoline, resulting in decreased fuel efficiency and mileage, as more fuel is required to produce the same amount of energy.
Phase Separation: Ethanol and gasoline can separate in the presence of water, leading to ethanol and water at the bottom of the fuel tank, causing potential engine malfunction or damage.
Engine Deposits: Ethanol can contribute to the formation of deposits within the engine and fuel system, which can decrease engine performance and fuel efficiency.
Cold Weather Issues: Ethanol fuels can be harder to ignite in colder temperatures, potentially leading to difficulty starting the engine.
Increased Emissions: While ethanol is a renewable fuel and can reduce greenhouse gas emissions, it can increase the emission of certain pollutants like acetaldehyde.
Shortened Shelf Life: Fuel containing ethanol can have a shorter shelf life and may degrade more quickly than ethanol-free fuel, especially if stored improperly.
Varnish Formation: Ethanol may contribute to forming a varnish inside the fuel system and engine, which can impede performance and necessitate additional maintenance.
Benefits of Ethanol-Free Gas for Lawn Equipment
Improved Fuel Efficiency
Ethanol-free gas contains more energy per gallon than ethanol-blended fuels, which can improve fuel efficiency and performance in lawn equipment.
Reduced Corrosion and Deposits
Without ethanol, which attracts moisture, there is less risk of corrosion within the engine and fuel system, and fewer harmful deposits are formed, ensuring smoother operation.
Extended Equipment Life
Ethanol-free gas can reduce wear and tear on engine components, extending the life of lawn equipment and reducing the need for repairs and maintenance.
Stable Fuel for Storage
Ethanol-free gas has a longer shelf life and does not degrade as quickly as ethanol-blended fuels, making it suitable for equipment that is not used regularly, such as seasonal lawn tools.
Fewer Cold Start Problems
Ethanol-free gas can alleviate cold start issues, ensuring lawn equipment starts more easily in lower temperatures than ethanol-blended fuels.
Lower Maintenance Requirements
Due to reduced deposits and corrosion, lawn equipment running on ethanol-free gas often requires less frequent maintenance, saving time and costs in the long run.
Preservation of Fuel System Components
Ethanol-free gas is less likely to damage plastic, rubber, and metal components within the fuel system, preserving the integrity and functionality of the equipment.
Optimal Performance
Lawn equipment often runs more efficiently and effectively on ethanol-free gas, ensuring optimal performance and reliability for tasks such as mowing and trimming.
What do E0 and E10 Gas mean?
E0 and E10 are terms used to describe the ethanol content in gasoline. E0 gas refers to gasoline containing no ethanol, meaning it is 100% pure. On the other hand, E10 gas contains 10% ethanol and 90% gasoline. E10 is commonly found at gas stations as it’s a standard fuel for many vehicles. The ethanol in E10 can attract moisture, potentially leading to engine issues in certain types of equipment, especially over time, which is why some users prefer E0 for small engines and equipment like lawn mowers.
