The Ultimate Guide to Gas Stabilizers for Lawn Mowers
As the mowing season comes to a close, many lawn mower owners face the daunting task of preparing their equipment for storage. One critical factor that often gets overlooked is the fuel left in the mower’s tank. Gasoline can degrade over time, leading to issues when you try to start your mower in the spring. This is where fuel stabilizers come into play. Fuel stabilizers are chemical additives that help prolong the life of your fuel, ensuring your lawn mower runs smoothly even after months of inactivity. This guide will explore the different types of gas stabilizers, how they work, and the best practices for using them effectively.

Understanding Fuel Stabilizers
Fuel stabilizers are essential for any lawn mower owner looking to maintain their machine’s performance. They work by preventing the breakdown of gasoline, which can occur due to oxidation and evaporation. When fuel sits in your mower’s tank, it can become stale, leading to gumming and varnishing that clogs the fuel system.
How Do Fuel Stabilizers Work?
When you add a fuel stabilizer to your gasoline, it inhibits the chemical reactions that lead to degradation. The stabilizer forms a protective layer around the fuel molecules, helping to prevent oxidation. This process helps keep the fuel fresh and minimizes the formation of harmful deposits that can clog fuel lines and injectors.
Benefits of Using Fuel Stabilizers
- Prevents Engine Problems: By keeping fuel fresh, stabilizers help avoid issues like hard starting and rough idling.
- Extends Equipment Life: Regular use of stabilizers can prolong the life of your lawn mower by preventing damage from stale fuel.
- Saves Time and Money: Preventative maintenance with stabilizers can save you costly repairs and time spent troubleshooting engine issues.
How to Choose the Right Fuel Stabilizer
When it comes to selecting the right fuel stabilizer for your lawn mower, consider the following factors:
1. Type of Fuel
Different stabilizers are designed for specific types of fuel. If your mower uses ethanol-blended gasoline, a stabilizer like EthanolShield is ideal. For standard gasoline, STA-BIL or Briggs & Stratton stabilizers are great choices.
2. Duration of Storage
Consider how long you plan to store your mower. If it will be idle for several months, choose a stabilizer with a longer effectiveness duration, such as PRI-G or Sea Foam.
3. Additional Features
Some stabilizers offer additional benefits, like cleaning properties. For instance, Star Tron not only stabilizes fuel but also cleans the fuel system, enhancing performance.
How to Use Fuel Stabilizers in Lawn Mowers
Using a fuel stabilizer is straightforward, but following the right steps ensures optimal performance:
Step 1: Choose the Right Stabilizer
Select a stabilizer based on your mower’s fuel type and your storage duration. Refer to the table above for options.
Step 2: Add Stabilizer to Fuel
Pour the recommended amount of stabilizer into your fuel tank. Typically, this is about 1 ounce of stabilizer for every 2.5 gallons of gasoline.
Step 3: Fill Up the Tank
Fill the tank completely with fresh gasoline. A full tank reduces the risk of moisture accumulation.
Step 4: Run the Engine
Start your mower and let it run for about 5-10 minutes. This allows the stabilizer to circulate through the fuel system, protecting it from gumming and varnishing.
Step 5: Store Properly
After treating your fuel, store your mower in a cool, dry place, away from direct sunlight.
