Understanding Gasoline and Your Husqvarna Mower
The gasoline your Husqvarna lawnmower uses is its lifeblood. It provides the energy to power the engine and keep those blades spinning. But not all gasoline is created equal.
Octane Rating: The Fuel’s Powerhouse
The octane rating on a gasoline pump reflects the fuel’s resistance to knocking or pinging. Higher octane gas burns more slowly and smoothly, preventing premature detonation in the engine’s combustion chamber. While a higher octane number might seem better, it’s not always necessary.
Why You Don’t Need High Octane for Your Husqvarna
Husqvarna lawnmowers are designed to run efficiently on regular unleaded gasoline with an octane rating of 87 or higher. Using higher octane gasoline (like premium) won’t provide any noticeable performance gains in your mower. It’s a waste of money and won’t improve your mower’s lifespan.
Lower Octane: When to Be Cautious
Using gasoline with an octane rating lower than 87 could lead to engine knocking or pinging, potentially causing damage to your engine over time. The lower the octane number, the more likely your mower will experience these issues, especially when working on hills or under heavy loads.
Ethanol: A Friend or Foe?
Ethanol is a biofuel often blended with gasoline, primarily to reduce reliance on fossil fuels and provide environmental benefits. However, ethanol can be problematic for small engines, like those found in lawnmowers.
The Downsides of Ethanol in Lawn Mower Fuel
- Corrosion: Ethanol attracts moisture, which can lead to corrosion within the fuel system, causing fuel lines and carburetor parts to rust.
- Gum & Varnish Buildup: Ethanol can break down over time, leaving behind sticky residues that clog fuel filters and carburetor jets, impacting engine performance.
- Shortened Fuel Life: Ethanol blends have a shorter shelf life than pure gasoline, meaning they degrade faster and can cause engine problems if left in the fuel tank for extended periods.
Ethanol-Free Gas: The Safer Choice
To avoid the potential problems associated with ethanol, consider using ethanol-free gasoline. You can find it at many gas stations, often labeled as “non-oxygenated” or “ethanol-free.” Ethanol-free gas offers longer storage life and minimizes the risk of fuel system corrosion and clogging.
The Importance of Fresh Fuel
Even if you choose the right gas, it’s crucial to keep your fuel fresh. Stale gas can lead to performance issues and damage to your engine.
Fuel Shelf Life and Recommendations
Generally, gasoline can remain usable for 30 to 60 days. However, this can vary depending on storage conditions and the presence of ethanol.
Signs of Stale Fuel
- Engine Stalling or Difficulty Starting: Stale fuel might not ignite properly, causing the engine to stall or struggle to start.
- Reduced Power: The engine may lose power due to the fuel’s decreased energy content.
- Gum & Varnish Buildup: Over time, stale fuel can leave behind residues that clog fuel lines and carburetor components, affecting performance and even requiring repairs.
Tips for Keeping Your Fuel Fresh
- Use Fuel Stabilizer: A fuel stabilizer helps prevent the breakdown of gasoline, extending its shelf life and reducing the risk of gum and varnish buildup.
- Store Fuel Properly: Keep your gasoline containers tightly sealed, in a cool, dry place away from direct sunlight to prevent evaporation and degradation.
- Use Fuel Within 30 Days: If you don’t anticipate using the fuel within 30 days, consider using a stabilizer or running the lawnmower until the fuel tank is empty to minimize the risk of stale fuel issues.
Taking Care of Your Husqvarna: Best Practices for Gas
Choosing the right gas is just the first step in maintaining your Husqvarna lawnmower. Here are some additional tips to ensure your mower runs smoothly and lasts for years to come:
Fuel Tank Cleaning and Maintenance
- Regular Cleaning: Periodically clean your fuel tank to remove any debris or sediment that may have accumulated. This helps ensure clean fuel reaches the engine.

- Fuel Filter Replacement: Replace the fuel filter regularly according to the manufacturer’s recommendations. A clogged filter can restrict fuel flow and hinder engine performance.
Carburetor Cleaning
- Importance of Cleaning: The carburetor is a critical component of your mower’s fuel system. It mixes fuel and air before sending the mixture to the engine. Over time, debris and gum buildup can clog the carburetor, causing performance issues.
- Cleaning Options: You can clean the carburetor yourself using a carburetor cleaning kit or take your mower to a qualified technician for professional cleaning.
Beyond the Fuel: General Maintenance Tips
- Regular Oil Changes: Changing the engine oil regularly helps keep the engine lubricated and running smoothly.
- Air Filter Replacement: A clean air filter ensures the engine receives adequate airflow, improving performance and fuel efficiency.
- Blade Sharpening: Sharp blades provide a clean, even cut, reducing stress on the engine and improving the overall mowing experience.
Conclusion
