Knowing how to properly fill your lawn mower with gas is a fundamental skill for any homeowner with a gas-powered mower.
It might seem straightforward, but there are a few crucial steps and safety precautions to keep in mind to ensure you do it right, every time. We’re here to walk you through the entire process, from selecting the right fuel to safely topping off your mower’s tank, so you can get back to enjoying a perfectly manicured lawn without any hitches.
Mastering the Art: How to Fill Your Lawn Mower with Gas
Keeping your lawn mower fueled up and ready to go is an essential part of lawn care. It’s a simple task, but doing it correctly ensures your mower runs efficiently, lasts longer, and most importantly, that you stay safe. Let’s break down exactly how to fill a lawn mower with gas, covering everything from fuel types to the nitty-gritty of the refueling process.
Why Proper Fueling Matters
You might be thinking, “It’s just gas, how complicated can it be?” Well, the answer is: more than you might think. Using the wrong type of fuel, overfilling the tank, or refueling in unsafe conditions can lead to a host of problems. These can range from minor inconveniences like engine sputtering to more serious issues like engine damage or even fire hazards. A little knowledge goes a long way in preventing these headaches.
Choosing the Right Fuel
This is arguably the most critical step. Not all gasoline is created equal, and your lawn mower has specific needs.
Gasoline Types and Octane Ratings
Most modern lawn mowers are designed to run on regular unleaded gasoline. You’ll typically see recommendations for an octane rating of 87. Avoid using premium fuels unless your mower’s manual specifically recommends it (which is rare for residential mowers). Higher octane fuels don’t offer any benefit to a standard lawn mower engine and are simply a waste of money.
Ethanol and Its Impact
A significant consideration today is the presence of ethanol in gasoline. Ethanol is an alcohol-based additive that can absorb water and cause corrosion in fuel systems over time. Many lawn mower manufacturers recommend using gasoline with no more than 10% ethanol (often labeled as E10). Some engines, especially older ones, can be sensitive to ethanol. If you’re unsure, check your owner’s manual. Many gas stations offer ethanol-free gasoline, which is the ideal choice for small engines if available and affordable.
Fuel Stabilizers: Your Mower’s Best Friend
If you don’t use your mower regularly, or if you store it for extended periods (like over winter), using a fuel stabilizer is highly recommended. Gas degrades over time, leading to gumming and varnish buildup in the carburetor. A stabilizer prevents this degradation, keeping the fuel fresh and your engine running smoothly when you finally need it.

- Before storing the mower for more than 30 days.
- When purchasing gasoline that will be stored for a while.
- To ensure fuel remains fresh in the tank during the mowing season if you use it infrequently.
What to Avoid
- Diesel fuel: Absolutely never put diesel in a gasoline engine.
- Leaded gasoline: This is mostly a concern for very old equipment.
- E85 or higher ethanol blends: These are not compatible with most lawn mower engines.
- Old, stale gasoline: Gas that’s been sitting for months can cause starting problems and engine damage.
Safety First: Before You Refuel
Refueling a lawn mower involves handling flammable liquids, so safety should always be your top priority. Taking a few precautions can prevent accidents.
1. Let the Engine Cool Down
Never refuel a hot engine. The engine components, especially the muffler, can be extremely hot after use. A hot surface can easily ignite gasoline fumes, leading to a dangerous fire. Always allow the mower to cool for at least 15-20 minutes after you’ve finished mowing before attempting to refuel.
2. Find a Safe, Well-Ventilated Area
Refuel your lawn mower outdoors in an open area. Avoid refueling in enclosed spaces like garages or sheds, as the fumes can build up and create an explosion risk. Ensure there are no open flames, sparks, or smoking nearby. This includes pilot lights on water heaters or other appliances.
3. Turn Off the Engine
This might seem obvious, but it’s crucial. The engine must be completely off and cool before you even think about opening the fuel cap.
4. Wear Appropriate Gear (optional but Recommended)
While not always mandatory, wearing gloves can protect your hands from gasoline and keep them from smelling. Safety glasses are also a good idea to protect your eyes from any accidental splashes.
The Step-by-Step Refueling Process
Now that you’ve chosen the right fuel and taken safety precautions, let’s get to the actual refueling. It’s a straightforward process, but attention to detail is key.
Step 1: Locate the Fuel Tank and Cap
Most lawn mowers have a fuel tank located on the top of the engine. The fuel cap is usually a screw-on or flip-top cap. Consult your owner’s manual if you’re having trouble finding it.
Step 2: Prepare Your Fuel Container
Use an approved portable gasoline container. These are specifically designed for storing and dispensing fuel and have safety features like flame arrestors. Make sure the container is clean and free of debris. If you’re using a gas can that’s been stored for a while, check for any sediment or rust inside.

Step 3: Open the Fuel Cap
Carefully unscrew or unlatch the fuel cap. Do this slowly to release any pressure that might have built up in the tank. Be mindful of any potential fuel or vapor release.
Step 4: Insert the Spout and Begin Pouring
Gently insert the spout of your fuel container into the lawn mower’s fuel tank opening. Avoid forcing it. If your fuel container has a vent, open it to allow for smoother pouring. Begin pouring the gasoline slowly and steadily.
Step 5: Fill the Tank (but Don’t Overfill!)
This is where many people make a mistake. Do not fill the tank completely to the brim. Leave about 1-2 inches of headspace at the top. This space is crucial for fuel expansion due to temperature changes and prevents fuel from spilling out when the engine is running or the mower is tilted. Overfilling can lead to fuel leaking, potential fire hazards, and damage to the engine or carburetor.
Tip: Many fuel spouts have an automatic shut-off mechanism. When the fuel level reaches the spout, it will often click or stop flowing. This is a helpful indicator, but still keep an eye on the fuel level yourself.
Step 6: Secure the Fuel Cap
Once you’ve filled the tank to the appropriate level, carefully replace the fuel cap. Ensure it is screwed on tightly or latched securely to prevent leaks and the entry of dirt or moisture.
Step 7: Clean Up Any Spills
If you happen to spill any gasoline, wipe it up immediately with a rag. Gasoline is highly flammable, and even a small spill can be a fire risk. Dispose of the rag properly (e.g., in a metal container away from ignition sources).
Troubleshooting Common Fueling Issues
Even with the best intentions, you might run into a few snags. Here’s how to handle them:
- Spilling Fuel: If you spill a little, wipe it up immediately. If you spill a lot, move the mower away from the spill area and ventilate the surrounding space before attempting to start it.
- Fuel Leaking After Filling: This usually indicates an improperly secured fuel cap or an overfilled tank. Check the cap and ensure there’s adequate headspace.
- Mower Won’t Start After Refueling: This could be due to stale fuel, a flooded carburetor (if you overfilled and then tried to start it immediately), or an airlock in the fuel line. Try waiting a bit, ensuring the cap is on correctly, and attempting to start again. If it persists, you might need to check the spark plug or carburetor.

- Keep a Dedicated Fuel Container: Don’t use containers that have held other chemicals.
- Store Fuel Properly: Store gasoline in an approved container in a cool, dry, well-ventilated area away from living spaces and ignition sources.
- Check Your Owner’s Manual: It’s your best resource for specific fuel recommendations and maintenance tips for your particular mower model.
- Consider a Funnel: A long-neck funnel can make it easier to fill the tank without spills, especially on mowers with hard-to-reach fuel caps.
- Refuel Before Storing: If you’re putting your mower away for the season, it’s often recommended to fill the tank with fresh fuel and a stabilizer. This prevents condensation from forming in an empty tank and keeps the fuel system clean.
Fueling Different Types of Mowers
While the general principles are the same, there are slight variations for different mower types:
Rotary Mowers (push and Riding Mowers)
These are the most common. They typically have a simple fuel tank with a cap, and the process described above applies directly. Riding mowers might have larger fuel tanks and sometimes a fuel gauge.
Reel Mowers (manual)
These don’t use gasoline at all! They are powered by human effort, making them an eco-friendly and quiet option. No fueling required!
Electric Mowers (corded and Cordless)
Electric mowers, whether corded or battery-powered, also do not require gasoline. They are powered by electricity. Cordless models use rechargeable batteries, and corded models plug into a standard outlet. These are excellent alternatives if you want to avoid gasoline altogether.
Environmental Considerations
Handling gasoline requires responsibility towards the environment.
- Minimize Spills: As mentioned, spills can contaminate soil and water.
- Proper Disposal of Rags and Containers: Never pour gasoline-soaked rags down the drain or into regular trash. Check with your local waste disposal services for proper hazardous waste disposal.
- Consider Alternatives: If environmental impact is a major concern, explore electric or manual reel mower options.
When to Seek Professional Help
While learning how to fill a lawn mower with gas is a DIY task, there are times when you might need a mechanic:
- If your mower consistently has starting issues after refueling, even with fresh fuel.
- If you suspect a fuel leak that you cannot easily fix.
- If you accidentally put the wrong type of fuel (e.g., diesel) into the tank. This requires immediate professional attention to drain and clean the fuel system.
- If you’re uncomfortable performing any of these steps, it’s always better to ask for assistance.
By following these guidelines, you’ll ensure your lawn mower is always ready for action, running smoothly, and most importantly, that you’re refueling it safely and efficiently. Happy mowing!
