What Is Fuel Stabilizer and Is It Necessary?

what is fuel stabilizer

You just placed your half-full gas can in the garage and don’t anticipate using it soon. Yet, a thought crosses your mind: is fuel stabilizer necessary? The answer could be yes.

A fuel stabilizer is a solution of antioxidants and lubricants designed to repel water and limit evaporation. Since gasoline expires in 3 to 6 months, adding a small amount of fuel stabilizer will keep your fuel fresh and effective.

To answer other questions you may have, our experts compiled a list of what to know about fuel stabilizers.

How to Use Fuel Stabilizer

There are two ways to use fuel stabilizer. If storing fuel in a gas can for 3 months or more, follow the instructions to put the right amount of stabilizer in the can. Then add in the fuel and seal the cap.

You can also add stabilizer directly to the fuel tank of your car, lawn mower, snow blower, chainsaw, generator, and more.

To do so, put the designated amount of stabilizer into a fuel tank that’s less than full and then top off the fuel level. Start the engine and allow it to run for 10 minutes. That way, the stabilizer mixes with the fuel that enters the fuel injection system or carburetor, preventing gummy deposits.

How Long Does Fuel Stabilizer Last?

There are different brands of fuel stabilizers on the market, each with its own advantages. Depending on the product you use, a stabilizer can lengthen gasoline’s shelf life to 1 to 3 years.

Can You Add Fuel Stabilizer to Old Gas?

Fuel stabilizers are a preventative measure. Gasoline naturally degrades over time, oxidizing and evaporating, and fuel stabilizers can’t reverse this process. They work best when added to new gasoline.

Can You Use Too Much Fuel Stabilizer?

Luckily, accidentally using a little extra fuel stabilizer won’t affect much; it’ll mainly waste product. On the other hand, if the ratio is widely off, it could dilute your gasoline.
