Adding Fuel Stabilizer in a Lawn Mower

A fuel stabilizer is essential while storing the mower for an extended time because it helps you keep the gas fresh for a long time.

However, you must mix the correct ratio of fuel stabilizer with gasoline in your lawn mower.

The stabilizer will protect the fuel from gumming and pitting up. Again, your mower will start easily from storage while you want to use it.

When adding fuel stabilizer, consider these tips:

1. Mix Depending On Stabilizer Brand

The first thing to consider before mixing stabilizer with gasoline is the brand of the stabilizer. Each brand has recommended specific ratios indicated on the stabilizer label.

Different brands will have specific ratio recommendations. Therefore, the essential thing is noting the ratios indicated on the stabilizer brand. And don’t consider the brand of your lawn mower.

2. Stabilize All Fuel Types

It doesn’t matter the type of your mower’s engine. Some require a mixture of cycle oil with gasoline, while others only straight gasoline. Use a fuel stabilizer because it will protect your fuel tank against moisture.

The ratio you add to any type of fuel used will be the same. However, follow the brand’s recommendation to ensure you use the proper amount.

Perhaps you use gasoline fuel blended with ethanol; adding a fuel stabilizer will lengthen its life span. But only use fuel stabilizer recommended for gas-ethanol mixtures.

3. Mix With Fresh Gasoline

If you want to keep your engine starting easy after the offseason, mix recommended ratio of fuel and stabilizer.

Remember that a fuel stabilizer will only work after mixing it with fresh gasoline. Even after you add to bad gasoline, the fuel stabilizer will not refreshen it.

If you want to get the benefits of a fuel stabilizer, mix the gas and recommended ratio of fuel stabilizer to fill the mower’s tank.

When done, run your mower’s engine for 10 minutes to help circulate the fuel mixture in the system. The mixture will protect the engine’s carburetor easily.

4. Filter or Pour

Only use the fuel stabilizer when you plan to store the mower for over 30 days. Perhaps you have a small mower that you infrequently use, extend the life of its fuel by adding a fuel stabilizer.

Sometimes, you may not want to measure fuel stabilizer into the gasoline. Check those manufacturers that make a cartridge having a fuel stabilizer.

Then you can snap it inside your mower’s gas cap. The cartridge will dip the fuel stabilizer slowly into your mower’s gasoline.

Why Use a Fuel Stabilizer?

The fuel stabilizer will keep your mower’s gasoline fresh and effective for use for about two years.

Chemical reactions in the stored fuel and the evaporation of volatile components make the liquid fuel not ignite properly.

Depending on how you store your lawn mower, it may take less than three months for fuel to go bad.

Old fuel leaves gummy deposits inside sensitive parts of the engine. Unless you use a fuel stabilizer that prevents it from happening, the bottom line will be trouble.

That said, consider these tips:

• When to use a fuel stabilizer

If you want to use a fuel stabilizer, it will depend on two situations. First, when storing fuel gas in the can for some months. In such a situation, add recommended fuel stabilizer in a can, add gasoline, and seal the cap.

The other situation is when adding a fuel stabilizer directly into the mower’s fuel tank. Put less than full fuel in the fuel tank and add recommended amount of stabilizer.

When done, top off to fill the tank to the maximum level and start the engine. The engine should run for about 10 minutes to mix the stabilizer with fuel in the carburetor.

• Fuel Stabilizer to Use

You should use a fuel stabilizer for all types of engines – either diesel or gasoline. However, it will depend on the stabilizer brand because some brands are formulated for diesel or gasoline fuel. There are also those brands for dual purposes; therefore, read the labels carefully.

• Amount of Stabilizer to Use

You can find stabilizer instructions on the bottle indicating the amount you should add to the fuel. The thing you will find is that the quantities specified there are small.

Depending on the brand recommendation, a lawn mower may need one or two tablespoons of the fuel stabilizer. Adding the correct amount will allow your gasoline to burn cleanly after years of storage.
