Where to Buy Lawn Mower Fuel?

The warm weather is finally here, and with it comes the dreaded task of mowing the lawn. But before you can get started, you need to make sure you have the right fuel for your lawn mower. This article will guide you through the different places where you can find the best lawn mower fuel, including gas stations, home improvement stores, and even online retailers. We’ll also cover the important factors to consider when choosing fuel, such as octane rating and ethanol content. So, let’s get started and ensure your lawn mower is ready to tackle your grass.

Where to Buy Lawn Mower Fuel?

There are several places where you can buy gasoline for your lawn mower, each with its own pros and cons. Let’s explore some of the most common options.

Gas Stations:

This is the most obvious place to buy fuel, and for good reason. Most gas stations offer a variety of fuel options, including regular, mid-grade, and premium gasoline. They’re typically open long hours and conveniently located, making them an easy choice for many homeowners.


  • Wide availability: Gas stations are everywhere, making it easy to find fuel when you need it.
  • Variety of options: Gas stations typically offer several different grades of fuel, allowing you to choose the best option for your mower.


  • Higher price: Gas station fuel is often more expensive than other options, especially if you’re buying in small quantities.
  • Ethanol content: Most gas stations sell gasoline with ethanol, which can damage older lawn mowers.

Home Improvement Stores:

Home improvement stores like Home Depot and Lowe’s also sell fuel, often in pre-mixed containers. These containers usually contain a gasoline/oil mixture specifically designed for small engines.


  • Convenience: Home improvement stores are often located close to where you might be buying other lawn care supplies.
  • Pre-mixed fuel: Pre-mixed fuel eliminates the need to mix your own, making it easier for less experienced users.


  • Limited variety: Home improvement stores generally offer only pre-mixed fuel, which might not be suitable for all lawn mowers.
  • Price: Pre-mixed fuel is usually more expensive per gallon than buying gasoline and mixing it yourself.

Online Retailers:

While not as common as other options, you can also purchase fuel online through retailers like Amazon. This is a great option if you need a specific type of fuel, such as non-ethanol gasoline, and don’t want to spend time searching for it locally.


  • Specialty fuel options: Online retailers can offer a wider range of fuel options, including non-ethanol gasoline and pre-mixed fuel blends.
  • Delivery: Ordering fuel online allows you to have it delivered directly to your door, which can be convenient if you have a busy schedule.


  • Shipping costs: Shipping fuel can be expensive, especially if you’re ordering a small quantity.
  • Limited availability: Not all online retailers sell gasoline, and even those that do might not have the specific type of fuel you need.

Factors to Consider When Choosing Fuel:

Once you’ve determined where to buy fuel, you need to choose the right type for your lawn mower. Here are some factors to keep in mind:

Octane Rating:

Octane rating is a measure of a fuel’s resistance to knocking or detonation. Higher octane ratings are designed for high-performance engines that operate at higher compression ratios. Most lawn mowers run on regular gasoline with an octane rating of 87. However, some newer models may require higher octane fuel, so consult your owner’s manual.

Ethanol Content:

Ethanol is a biofuel that is often added to gasoline to reduce emissions and promote energy independence. However, ethanol can be harmful to older lawn mowers and other small engines. Ethanol absorbs moisture from the air, which can lead to corrosion and damage within the engine.

Here are some tips for minimizing the potential damage of ethanol:

  • Use fuel stabilizer: Fuel stabilizer helps to prevent the deterioration of gasoline by reducing the rate of oxidation.
  • Store fuel properly: Store fuel in airtight containers in a cool, dry place to prevent the absorption of moisture.
  • Don’t let fuel sit for too long: Use fuel as soon as possible after purchasing it, and try to avoid storing it for extended periods.
  • Consider non-ethanol gasoline: Non-ethanol gasoline is specifically formulated for small engines and can be a good choice for older lawn mowers.

Pre-mixed vs. Mixing Your Own:

Pre-mixed fuel is convenient, but it can be expensive. Mixing your own fuel can be more cost-effective, but it’s important to ensure you are using the correct ratio of gasoline to oil. The recommended ratio is usually 40:1 or 50:1, but it’s best to check your owner’s manual for the specific ratio for your mower.

Tips for Choosing the Right Fuel:

  • Check your owner’s manual: The best way to determine the type of fuel your lawn mower needs is to consult your owner’s manual.
  • Look for fuel with a low ethanol content: If possible, opt for fuel with a low ethanol content, such as 10% or less.
  • Consider using fuel stabilizer: Add fuel stabilizer to your gasoline to help prevent the formation of varnish and gum.
  • Store fuel properly: Store fuel in airtight containers in a cool, dry place.


Choosing the right fuel for your lawn mower is essential for its performance and longevity. By considering factors such as octane rating, ethanol content, and pre-mixed vs. mixed fuel, you can make an informed decision that will keep your mower running smoothly for years to come. Remember, a little bit of knowledge can go a long way towards ensuring your lawn mower is ready to tackle your lawn all season long.


1. What kind of fuel do lawn mowers use?

Most gas-powered lawn mowers use regular unleaded gasoline, often referred to as 87 octane. This is the same fuel you would use in your car. However, it’s crucial to avoid using fuel with ethanol additives, as these can damage your lawn mower’s engine. Look for “gasoline” or “unleaded” on the pump, as opposed to “gasohol” or “E10.”

Additionally, some newer mowers, especially those with 4-stroke engines, might require a specific fuel blend. Refer to your owner’s manual for the correct fuel type for your mower.

2. Where can I buy lawn mower fuel?

You can find gasoline for your lawn mower at most gas stations. While some stations might label specific pumps for “lawn mower fuel,” it’s generally safe to use the same pumps you would use for your car, just ensure you’re selecting the correct type of fuel (unleaded, without ethanol).

Alternatively, some hardware stores, home improvement centers, and outdoor power equipment dealers sell small containers of gasoline specifically for lawn mowers. These options are convenient, but they may be more expensive than buying fuel at a gas station.

3. Should I use pre-mixed fuel?

Pre-mixed fuel is a blend of gasoline and oil, specifically designed for 2-stroke engines. If your mower has a 2-stroke engine, you’ll need to use pre-mixed fuel. The ratio of gasoline to oil is usually printed on the fuel container.

If your lawn mower has a 4-stroke engine, you should not use pre-mixed fuel. These engines have a separate oil reservoir for lubrication and require only pure gasoline.

4. Can I use old gasoline in my lawn mower?

It’s not recommended to use old gasoline in your lawn mower. Gasoline degrades over time, losing its volatility and becoming less efficient. This can lead to poor engine performance and even damage your mower’s engine.

If you have old gasoline, it’s best to dispose of it properly. Check with your local waste management agency for instructions. It’s always better to buy fresh gasoline whenever possible.

5. How much fuel do I need to buy?

The amount of fuel you’ll need depends on the size of your lawn and the fuel tank capacity of your mower. It’s a good idea to keep a spare gas can on hand, so you’re not caught short when mowing.

However, avoid filling your mower’s tank completely. Leave some space for expansion as the fuel heats up, preventing spills and potential issues.

6. How do I safely store gasoline?

When storing gasoline, it’s crucial to prioritize safety. Keep gasoline in a well-ventilated area away from heat and open flames. Use a clearly labeled, approved fuel container with a tight-fitting lid.

Regularly inspect your fuel containers for leaks and damages. Store fuel in a cool, dry place and avoid exposing it to direct sunlight.

7. What are the potential dangers of using gasoline?

Gasoline is a highly flammable substance and should be handled with care. Always wear appropriate safety gear, including gloves and eye protection, when handling gasoline.

Never smoke or use open flames near gasoline. Keep gasoline containers away from children and pets. If you spill gasoline, clean it up immediately and properly dispose of any rags or materials that came into contact with it.
