How to Use Fuel Stabilizer in Lawn Mower in 4 Simple Steps

When gasoline gets stored in the tank for more than a month, it oxidizes and thickens. After the offseason, you want to start the lawn mower and mow the grass. The engine starts misfiring, and in some cases, it malfunctions completely.

When maintained and stored in good condition, a lawn mower will help you maintain the yard. Therefore, while reserving a lawn mower, it is good to use a fuel stabilizer to avoid possible damage to the engine and fuel.

A fuel stabilizer is used to neutralize the alcohol components harmful to plastic and rubber in the machine. It can affect the carburetor functionality making it jammed up.

Leaving a fuel that is not stabilized for a long period will degrade and affect the engine functionality due to oxidation. Therefore, learn how to use fuel stabilizer in lawn mower below.

Let us get started:

How to Use Fuel Stabilizer in Lawn Mower

A fuel stabilizer is helpful to a lawn mower, and a gardener must use it to ensure the engine is in good condition.

As discussed below, there are steps to be followed while using the fuel stabilizer.

1. Empty the Fuel Tank

Fuel stabilizer is not added randomly in the tank. A certain ratio of fuel stabilizer to fuel must get recommended. You must know the amount of fuel in the tank; therefore, emptying the tank will give you an accurate amount of fuel.

You are advised not to estimate the amount of fuel in the tank. After all, adding more than the prescribed fuel will serve no good to the engine because it will malfunction. Adding less than specified will not prevent oxidation from taking place.

2. Add Stabilizer to the Tank

When you empty and measure the amount of fuel in the tank, you will know the amount of stabilizer required in the tank. Typically, the ratio gets indicated in the user’s manual of the fuel stabilizers.

The bottles have cuts used for measuring the amount of gasoline. Add the required fuel stabilizer to the fuel tank.

3. Add the Fuel

After the fuel stabilizer gets added, you must add the required ratio of the fuel to the tank. You are requested to add new fuel to reduce the risk of the old oil oxidizing before the stabilizer got added.

Remember, the fuel should get added to the stabilizer because it disperses evenly.

The tank should not get filled to a full tank to avoid spilling out to the compound; therefore, add up to ninety-five percent.

4. Start the Engine

Start the engine after adding the fuel and check all the required precautions. Allow it to run for about ten minutes to ensure that the stabilized oil runs through the engine and the carburetor.

When the engine fails to run, the stabilized oil will not serve the purpose because it will remain in the fuel tank.

By allowing the fuel to circulate, the stabilized fuel fits its purpose, and you can have peace of mind. You can be sure that there will be no breakdown when you restart the lawn mower for the next season.

Importance of Using Fuel Stabilizer

Using the fuel stabilizers will help remove the impurities from the fuel and keep the engine fresh.

4. Fuel Economy is Enhanced

    Hi, I’m Ricky. I’ve been involved in lawn care and landscaping from when I was 15. To be honest, I didn’t like the idea of pushing mowers, collecting grass clippings, and maintaining flowerbeds at the time. But having seem the passion my parents had for gardening and outdoors and the effort they put in maintaining the health and beauty of our landscape, I couldn’t help but not only admire their hard work but also I became a part of it. As someone who loves to spend time with nature’s best, I find myself learning a lot more about gardening and outdoors on a daily basis. Not to mention I love to share the knowledge I’ve gathered over the years with my readers at We Mow Dallas. To be clear, I don’t have a Master’s degree in gardening or anything like that. Everything I’ve learned about gardening, landscaping, and lawn care spring from passion and engagement with my parents. And with a ton of free information out there, plus the ability to run tests and determine what works best for lawn care and landscaping, every day is an opportunity to learn and implement something new. My goal with We Mow Dallas is to teach you exactly how to maintain your lawn and landscape. And since I walk the talk in reality, you shouldn’t hesitate to join me in this wonderful world of landscaping and lawn care. K Beatrice
