What Type of Fuel Does a Toro Lawn Mower Need?

The satisfying hum of a Toro lawnmower in action is music to any homeowner’s ears. But before you can enjoy that symphony of freshly cut grass, you need to understand the fuel that powers this magnificent machine. What type of fuel does a Toro lawnmower need? The answer, unfortunately, isn’t as simple as “just fill it with gasoline.” This article will delve into the intricate world of Toro lawnmower fuel, exploring different fuel types, their benefits, and how to choose the right fuel for your specific model. We’ll also provide helpful tips on storing and using fuel to ensure optimal performance and longevity for your beloved Toro mower.

In a nutshell, Toro lawnmowers generally require unleaded gasoline with an octane rating of 87 or higher. However, the specific fuel requirements can vary depending on the model and year of manufacture. Always consult your owner’s manual for the most accurate information.

Understanding Fuel Requirements for Your Toro Lawn Mower

The first step to choosing the right fuel for your Toro lawnmower is to understand the model and its specifications. While most Toro lawnmowers use standard unleaded gasoline, there are a few exceptions:

Toro TimeCutter Riding Mowers

Toro TimeCutter riding mowers stand out with their unique fuel requirements. They’re designed to run on E0 gasoline, also known as pure gasoline, which is completely free of ethanol. Ethanol, commonly added to gasoline as an alternative fuel source, can cause problems in small engines like those found in lawnmowers. Ethanol attracts moisture, leading to corrosion, gumming, and other issues.

Why does Toro choose E0 for TimeCutter mowers? The answer lies in their commitment to long-lasting performance and optimal fuel efficiency. Using E0 in TimeCutter mowers reduces the risk of fuel-related problems, ensuring smoother operation and extended engine life.

Checking Your Owner’s Manual

The most reliable source of information on your Toro lawnmower’s fuel requirements is your owner’s manual. This manual contains detailed instructions on fuel type, octane rating, and any specific recommendations for your model.

The Importance of Using the Right Fuel

Choosing the wrong type of fuel for your Toro lawnmower can lead to a variety of issues, including:

  • Reduced engine performance: Using low-quality fuel can lead to engine sputtering, loss of power, and difficulty starting.
  • Fuel system problems: Ethanol-based gasoline can cause corrosion, gumming, and fuel line blockage, leading to engine failure.
  • Shortened engine life: Improper fuel use can significantly reduce the lifespan of your Toro lawnmower’s engine.

Tips for Using and Storing Fuel Properly

  • Use Fresh Fuel: Always use fresh gasoline and avoid storing it for extended periods. Older fuel can degrade and lead to engine problems.
  • Store Fuel Properly: If you need to store gasoline, use a fuel stabilizer to prevent degradation and store it in a cool, dry place.
  • Clean Your Fuel System: Regularly clean your fuel system to prevent fuel line blockage and ensure optimal performance.


Selecting the right fuel for your Toro lawnmower is crucial for maximizing performance and extending the life of your machine. While most Toro models use standard unleaded gasoline, it’s essential to check your owner’s manual for specific fuel requirements for your particular model. Remember to prioritize fresh fuel, proper storage, and regular maintenance to keep your Toro lawnmower running smoothly for years to come.

Frequently Asked Questions

What type of fuel does a Toro lawnmower use?

Toro lawnmowers, like most gasoline-powered outdoor equipment, typically require unleaded gasoline with an octane rating of 87 or higher. You can use regular unleaded gasoline readily available at most gas stations.

It’s important to note that some older Toro models may have different fuel requirements, so it’s always best to consult your owner’s manual for specific instructions. The manual will provide details on the recommended fuel type, octane rating, and any other specific requirements.

Can I use E10 gasoline in my Toro lawnmower?

Yes, you can typically use E10 gasoline, which is a blend of 10% ethanol and 90% gasoline. Most modern Toro lawnmowers are designed to handle E10 without any issues. However, it’s always a good practice to consult your owner’s manual to confirm the compatibility of your specific model.

It’s worth noting that older Toro lawnmowers or models with fuel systems not designed for ethanol blends may experience problems with E10, such as fuel line damage or engine performance issues. If you have an older mower, consider using E0 gasoline (pure gasoline) or consult a mechanic for advice.

What is the best type of gasoline to use in a Toro lawnmower?

While regular unleaded gasoline with an octane rating of 87 or higher is suitable for most Toro lawnmowers, some users prefer to use higher-octane fuel, such as 89 or 91. This can be beneficial in certain situations, like when operating the mower in extreme heat or at high altitudes.

However, using higher-octane gasoline is not necessary in most cases and won’t provide any noticeable performance improvements. It’s important to note that using higher-octane fuel than recommended may actually reduce engine performance and fuel efficiency.

Can I use fuel stabilizer in my Toro lawnmower?

Yes, it is highly recommended to use fuel stabilizer in your Toro lawnmower, especially if you won’t be using it for an extended period. Fuel stabilizer helps prevent the formation of gums and varnish that can clog fuel lines and damage the engine.

Adding fuel stabilizer to the gas tank before storing your mower for the winter can help extend the life of the fuel and prevent problems when starting the mower in the spring. Check the fuel stabilizer instructions for the recommended dosage and application method.

Should I use fresh gas in my Toro lawnmower?

Using fresh gasoline in your Toro lawnmower is always a good practice. Older gasoline can degrade and develop moisture, which can lead to engine problems. It’s generally recommended to use gasoline that is less than 30 days old.

If you have old gas in your mower, it’s best to drain it and refill the tank with fresh gasoline. This will help ensure optimal performance and prevent any potential engine issues.

How do I store my Toro lawnmower during the off-season?

To store your Toro lawnmower during the off-season, it’s essential to follow a few steps to ensure its longevity. First, drain the fuel tank completely, as old gasoline can damage the fuel system. Then, run the engine until it runs out of fuel to clear any remaining fuel from the carburetor.

Next, change the oil and spark plug, and clean or replace the air filter. Finally, store the mower in a dry, clean, and well-ventilated location. Following these steps will help keep your Toro lawnmower in good condition for next season.

How often should I change the oil in my Toro lawnmower?

The frequency of oil changes in your Toro lawnmower depends on the usage and recommendations provided in your owner’s manual. Typically, it’s recommended to change the oil every 25 hours of use or every season, whichever comes first.

However, if you use your mower infrequently, you may only need to change the oil once a year. Regularly changing the oil helps ensure proper engine lubrication and prevent wear and tear. Always refer to your owner’s manual for specific guidelines regarding oil change intervals.
