Should You Use Ethanol-free Gas in Lawn Mowers?
Lawn mowers are an essential tool for maintaining a beautiful and healthy lawn. Whether you have a small backyard or a vast expanse of greenery, your lawn mower needs fuel to keep it running smoothly. However, with the increasing availability of ethanol-blended gasoline at the pumps, you may be wondering if it’s necessary or beneficial to use ethanol-free gas in your lawn mower. In this article, we’ll explore the advantages and disadvantages of ethanol-free gas and help you make an informed decision.
The Impact of Ethanol-blended Gasoline
Ethanol, a type of alcohol derived from plants like corn, has been added to gasoline in varying percentages for decades. It became more prevalent after the Energy Policy Act of 2005, which mandated the use of renewable fuels, including ethanol. Today, most gasoline contains up to 10% ethanol (E10), although higher blends like E15 and E85 are also available in certain regions.
While ethanol-blended gasoline has benefits such as reduced emissions and increased octane levels, it can have a negative impact on small engines, including those found in lawn mowers. Here are some key factors to consider:
- Phase Separation: Ethanol has a higher affinity for water than gasoline. When exposed to moisture, it can absorb water and separate from the fuel, resulting in a process called phase separation. This can lead to engine damage and performance issues.
- Corrosion: Ethanol is a solvent and can cause corrosion in metal and rubber components within the fuel system. Over time, this corrosion can lead to fuel leaks, clogged carburetors, and other costly repairs.
- Reduced Shelf Life: Ethanol attracts moisture, which can accelerate the process of fuel degradation. Ethanol-blended gasoline has a shorter shelf life compared to ethanol-free gas, leading to potential starting and running problems if the fuel has been sitting for an extended period.
- Increased Maintenance: The ethanol in gasoline can leave behind deposits and varnish inside the engine, leading to clogged fuel lines and fouled spark plugs. This can result in decreased performance and a need for more frequent maintenance.
- Lower Energy Content: Ethanol has a lower energy content compared to gasoline, meaning you may experience a slight decrease in power and fuel efficiency when using ethanol-blended gas in your lawn mower.
The Case for Ethanol-free Gas
Given the potential issues associated with ethanol-blended gasoline, it’s understandable why some lawn mower owners choose to use ethanol-free gas. Here are some of the potential benefits:
- Avoiding Ethanol-related Problems: By using ethanol-free gas, you can alleviate concerns about phase separation, corrosion, and fuel degradation, potentially extending the lifespan of your lawn mower.
- Improved Performance: Ethanol-free gas may provide better starting, smoother operation, and increased power output due to its higher energy content.
- Longer Shelf Life: Ethanol-free gas retains its freshness for a longer period, reducing the chances of fuel-related issues when your lawn mower sits idle for extended periods.
- Easier Cold Weather Starting: Ethanol can be problematic in cold temperatures, causing starting difficulties. Ethanol-free gas eliminates this concern, ensuring easier cold-weather starts.
Considerations for using Ethanol-free Gas
While ethanol-free gas may seem like the perfect solution for your lawn mower, there are a few factors to consider before making the switch:
- Availability: Ethanol-free gas might not be as readily available as ethanol-blended gasoline, depending on your location. You may need to do some research to identify nearby stations that offer this type of fuel.
- Pricing: Ethanol-free gas is typically more expensive than the ethanol-blended alternative. If you have a large lawn and use your mower frequently, the cost difference could add up over time.
- Environmental Considerations: Ethanol is a renewable fuel source, and its use reduces greenhouse gas emissions. It’s worth considering the environmental impact of using ethanol-free gas and weighing it against the potential benefits for your lawn mower.
- Manufacturer Recommendations: It’s essential to review your lawn mower’s user manual and warranty information. Some manufacturers specify the use of ethanol-blended gasoline and may void warranties if ethanol-free gas is used.
Using ethanol-free gas in your lawn mower can provide certain advantages, including avoiding potential ethanol-related problems and improving performance. However, it’s crucial to consider factors such as availability, pricing, and environmental considerations before making a decision. Review your mower’s manufacturer recommendations and consult with a local lawn care expert if you’re unsure. Ultimately, selecting the right fuel for your lawn mower will help ensure its longevity and reliable operation for years to come.

Frequently Asked Questions
Is it necessary to use ethanol-free gas in lawn mowers?
Whether or not it is necessary to use ethanol-free gas in lawn mowers largely depends on the specific model and manufacturer’s guidelines. While some lawn mowers can handle gasoline with ethanol content, others may suffer from performance issues or damage when using fuel that contains ethanol. It is essential to refer to the owner’s manual to determine the fuel requirements for your particular lawn mower.
What are the potential problems of using gasoline with ethanol in lawn mowers?
Using gasoline with ethanol in lawn mowers can lead to various problems. Ethanol has a corrosive nature that can damage the fuel system components, such as rubber gaskets, fuel lines, and carburetors, over time. It can also cause the formation of deposits that clog the fuel system or carburetor jets, leading to poor performance, hard starting, or engine stalling.
Will using ethanol-free gas improve the performance of my lawn mower?
Using ethanol-free gas may improve the performance of your lawn mower under certain circumstances. If your mower is designed to operate best with ethanol-free fuel or if you have experienced problems using gasoline with ethanol, switching to ethanol-free gas could potentially resolve these issues. However, if your lawn mower is specifically designed to run on fuel with ethanol content, using ethanol-free gas may not provide any noticeable improvements.
Where can I find ethanol-free gas for my lawn mower?
Ethanol-free gas can usually be found at certain gas stations or fuel distributors. These gas stations often advertise ethanol-free gasoline, commonly known as “pure gas” or “clear gas.” You can use online resources or mobile applications that provide updated lists of stations offering ethanol-free gas in your area.
Is ethanol-free gas more expensive than gasoline with ethanol?
Typically, ethanol-free gas tends to be slightly more expensive than gasoline with ethanol. The cost difference can vary depending on the region and availability of ethanol-free gas in your area. While the increased cost may be a consideration, it is important to weigh it against potential maintenance and performance issues that might arise from using fuel with ethanol in your lawn mower.
Can ethanol-free gas be used in other outdoor power equipment besides lawn mowers?
Yes, ethanol-free gas can be used in other outdoor power equipment besides lawn mowers. Many small engines, such as those found in chainsaws, leaf blowers, and generators, can benefit from using ethanol-free fuel. Just like with lawn mowers, it is crucial to check the manufacturer’s guidelines to determine the recommended fuel type for each specific piece of equipment.
