The warm weather is here, and you’re itching to get your lawn mower roaring and trim those overgrown patches. But before you head out to the gas station, consider this: is the fuel you’re buying the best for your lawn mower? Ethanol, a common additive in gasoline, can wreak havoc on small engines. This article will explore the reasons why ethanol-free gas is better for your lawn mower, where to find it, and how to ensure you’re making the right choice for your equipment.
The Problem with Ethanol in Lawn Mower Fuel
Ethanol is a biofuel derived from corn and added to gasoline to reduce dependence on fossil fuels and boost octane levels. However, it poses several challenges for small engines like those found in lawn mowers, weed trimmers, and generators:
- Ethanol attracts moisture: It’s hygroscopic, meaning it readily absorbs moisture from the air. This moisture, combined with ethanol, forms a corrosive mixture that can damage fuel lines, carburetors, and other engine parts.
- Ethanol degrades over time: It breaks down more quickly than gasoline, becoming gummy and sticky. This residue can clog fuel filters and injectors, leading to engine problems.
- Ethanol reduces fuel efficiency: It burns less efficiently than pure gasoline, leading to decreased power and increased fuel consumption.
Where to Buy Ethanol-Free Gas
Finding ethanol-free gas, often called “non-oxygenated gasoline,” requires a bit more effort than stopping at your usual gas station. Here’s where to look:
1. Specialty Fuel Stations
- Look for stations that specifically advertise ethanol-free gas. Some gas stations specialize in selling fuel blends for specific purposes, including small engines. They may call it “small engine fuel,” “marine fuel,” or “ethanol-free gasoline.”
- Contact your local gas stations: If you’re not sure if they carry ethanol-free gas, call ahead and ask.
2. Small Engine Dealerships and Repair Shops
- These businesses often sell ethanol-free gas specifically designed for small engines. They might even offer it in smaller containers, making it easier for you to store and transport.
- Many offer fuel storage solutions: If you plan to store fuel for an extended period, ask about fuel stabilizers and other storage tips.
3. Home Improvement and Hardware Stores
- Large retailers like Home Depot and Lowe’s often carry small quantities of ethanol-free gas. Check the fuel aisle or ask a staff member for assistance.
4. Online Retailers
- You can purchase ethanol-free gas online from various retailers. This option might be more convenient if you need a smaller quantity or live in an area with limited access to local retailers.
Tips for Choosing the Right Fuel
- Read the label: Always check the label on the gas pump or container for the ethanol content. Make sure it’s clearly marked “ethanol-free” or “non-oxygenated gasoline.”
- Ask questions: If you’re unsure about the fuel you’re buying, don’t hesitate to ask the gas station attendant or retailer for clarification.
- Buy fresh fuel: Ethanol degrades over time, so it’s best to buy fresh fuel whenever possible.
- Store fuel properly: If you need to store fuel, use a fuel stabilizer to prevent degradation and follow proper storage guidelines.
Why Ethanol-Free Gas is a Good Investment
- Improved engine performance: Ethanol-free gas burns cleaner, leading to smoother engine operation and increased power. This is especially important for older engines that are more susceptible to the damaging effects of ethanol.
- Reduced maintenance costs: By avoiding the corrosion and clogging caused by ethanol, you’ll likely experience fewer engine problems, leading to lower maintenance costs in the long run.
- Longer engine life: Ethanol-free gas helps protect your engine’s internal components, extending its lifespan and potentially saving you from costly replacements.
Conclusion
Choosing the right fuel for your lawn mower is crucial to ensuring its performance and longevity. While it might take a bit more effort to find ethanol-free gas, the benefits outweigh the inconvenience. By understanding the issues with ethanol and knowing where to find suitable alternatives, you can keep your lawn mower running smoothly and efficiently for years to come.
Frequently Asked Questions
What is ethanol-free gas and why do I need it for my lawnmower?
Ethanol-free gas is gasoline that does not contain ethanol, a type of alcohol that is commonly added to gasoline to reduce emissions. While ethanol can be beneficial for some vehicles, it can be detrimental to small engines like those found in lawnmowers, generators, and other outdoor equipment. Ethanol attracts moisture, which can lead to phase separation, where the gas and water separate, causing clogging and damage to the engine. Ethanol can also corrode engine parts and degrade fuel lines over time.
Using ethanol-free gas in your lawnmower helps to prevent these issues and extend the life of your equipment. It ensures that your engine runs smoothly and efficiently, with less risk of breakdowns or repairs.
Where can I find ethanol-free gas?
You can find ethanol-free gas at a variety of locations, depending on your area. Some gas stations, typically those that specialize in marine or recreational vehicle fuels, will offer ethanol-free gas. These stations are often located near marinas or boat ramps. You may also find ethanol-free gas at some convenience stores or hardware stores. Check online directories or call local gas stations to inquire about their offerings.
Alternatively, you can purchase ethanol-free gas in pre-mixed containers at many outdoor equipment retailers, hardware stores, or even online. This option can be convenient, but it may be more expensive than buying it directly from a gas station.
What is the difference between ethanol-free gas and regular gas?
Regular gasoline typically contains 10% ethanol, while ethanol-free gas is completely free of ethanol. This difference in composition affects the performance and lifespan of small engines. Ethanol-free gas is specifically designed to be used in engines that are sensitive to the negative effects of ethanol, like those in lawnmowers.
Regular gas can be used in your lawnmower, but it may lead to problems like engine damage, decreased fuel efficiency, and shorter engine life. Therefore, using ethanol-free gas is highly recommended for optimal performance and longevity of your lawnmower.
Is ethanol-free gas more expensive than regular gas?
Ethanol-free gas is often priced higher than regular gasoline. This is because it is a specialized fuel with specific production and distribution processes. The higher price is a reflection of the additional costs involved in creating and distributing this type of fuel.
However, consider that using ethanol-free gas can save you money in the long run by preventing engine damage and extending the lifespan of your lawnmower. You may also need fewer fuel additives, further reducing your costs.
Can I use ethanol-free gas in my car?
While ethanol-free gas is safe for most lawnmowers and other small engines, it is not recommended for use in most vehicles. Modern cars are designed to run on gasoline that contains ethanol, and using ethanol-free gas can affect the performance of your vehicle.
In some cases, ethanol-free gas can lead to engine problems, such as reduced fuel economy or engine knocking. Therefore, it is best to stick to the fuel type recommended by your vehicle’s manufacturer.
How long can I store ethanol-free gas?
Ethanol-free gas has a longer shelf life than regular gasoline. You can store ethanol-free gas for up to a year without experiencing significant degradation. This is because it does not contain ethanol, which attracts moisture and can lead to fuel deterioration.
However, it is always advisable to use fresh fuel whenever possible. If you are storing gas for an extended period, consider using fuel stabilizers to further extend its shelf life and prevent deterioration.
What are some tips for storing ethanol-free gas?
Storing ethanol-free gas properly can ensure it remains stable and usable for a long time. Here are some tips:
- Store in a cool, dark place. Direct sunlight and heat can accelerate the deterioration process.
- Use a fuel container specifically designed for gasoline. This will prevent leaks and spills.
- Keep the container airtight. This will prevent moisture from entering the gas and causing it to degrade.
- Add a fuel stabilizer. Fuel stabilizers help to prevent the formation of gums and varnishes that can clog fuel lines and injectors.
By following these tips, you can ensure that your ethanol-free gas remains in good condition for as long as possible.
