Fuel stabilizers are designed to maintain the quality of stored fuel and extend its lifespan. They are useful for those who don't drive their cars regularly or store them for long periods. Fuel stabilizers prevent the fuel from deteriorating, becoming stale, or oxidizing, which can cause engine problems and reduce fuel efficiency. The stabilizers are added to the fuel tank, and the engine is run for a few minutes to ensure the stabilizer gets mixed with the fuel. While fuel stabilizers can be beneficial, they don't provide a long-term solution, and fresh fuel is always recommended for optimal performance.
| Characteristics | Values |
|---|---|
| Purpose | To maintain the quality of stored fuel and prevent engine problems that might reduce fuel efficiency |
| Use case | For vehicles that are stored for long periods of time, such as seasonal equipment, classic cars, or boats |
| How it works | Prevents oxidation and evaporation of fuel, and stops the formation of sticky resins that can ruin a carburetor |
| Fuel type | Compatible with all grades of gasoline and diesel fuel, including ethanol and non-ethanol fuel types |
| Amount to use | A small amount is required, typically a tablespoon or two for a lawnmower or chainsaw gas tank |
| How to use | Add to a fresh, full tank of fuel, then run the engine for 5-10 minutes to distribute the stabilizer throughout the fuel system |
| Storage time | Fuel stabilizers can extend the shelf life of gasoline for up to 12 months, but it is recommended to use it within 6-8 months for optimal performance |

What You'll Learn
How does fuel stabilizer work?
Fuel stabilizers are designed to maintain the quality of stored fuel, not to improve gas mileage. They are suitable for all kinds of gasoline and diesel engines, including two-stroke motors found in chainsaws, snowmobiles, dirt bikes, and certain water pumps. They can also be used with all grades of gasoline, including gasoline that contains ethanol. However, it is always good to check the product label to be sure.
Fuel stabilizers can be used when storing fuel in an approved gas container or when adding it directly to the fuel tank that supplies an engine. If using a gas container, put the required amount of stabilizer in first, then add the fuel and seal the cap. If adding it to a fuel tank, put the required amount of stabilizer into the less-than-full tank, top off the fuel level, and then start the engine. It is recommended to run the engine for about 5 to 10 minutes to ensure the stabilizer gets mixed with the fuel and reaches the carburetor or fuel injection system. This will prevent gummy deposits and increase the chances of a quick and easy post-storage startup.
The optimal time to add a fuel stabilizer is when fueling up, especially if the vehicle or equipment will be stored for 30 days or more. Fuel stabilizers can help keep the fuel from becoming stale or oxidized and clogging up small ports in the fuel system. They can also help with water accumulation and allow old fuel to burn until the next fill-up. Generally, stabilized gasoline can be stored for up to 12 months, but it is recommended to use it within 6 to 8 months for optimal performance.
It is important to note that fuel stabilizers are not a miracle solution. They only help slow down the aging process of the fuel and provide a couple of extra months. While they can help maintain the fuel's quality, they do not improve its performance. Newer fuel will still burn cleaner, easier, and ignite better, leaving behind less varnish and carbon.

When to use fuel stabilizer
Fuel stabilizers are designed to maintain the quality of stored fuel, not to improve gas mileage. They are meant to keep the fuel from deteriorating over time. Fuel stabilizers are suitable for all kinds of gasoline and diesel engines, including two-stroke motors as found in chainsaws, snowmobiles, dirt bikes, lawn mowers, and certain water pumps.
Fuel stabilizers are ideal for those who own seasonal equipment, classic cars, or boats that tend to sit for more than three weeks at a time. They are also beneficial for those with multiple vehicles that are put into storage for extended periods. In these cases, using a fuel stabilizer can help prevent engine problems and maintain fuel quality.
If you plan to store your car for an extended period, such as over the winter, or if you don't plan on driving it for several months, it is recommended to add a fuel stabilizer to the gas tank. This will keep the gas from going bad and maintain its potency.
To use a fuel stabilizer, start by ensuring there is fresh gas in the tank, and the tank is about 95% full. Then, pour the recommended amount of fuel stabilizer into the tank, following the manufacturer's instructions. Finally, run the engine for about 5-10 minutes to ensure the stabilizer is distributed throughout the fuel system.

How much fuel stabilizer to use
Fuel stabilizers are designed to maintain the quality of stored fuel, not to improve gas mileage. They can, however, prevent engine problems that might reduce fuel efficiency. They are meant to keep the fuel from deteriorating over time. This is done by stopping the oxidation process, which means the chemicals in the gas do not break down over time.
Fuel stabilizers are suitable for all kinds of gasoline and diesel engines, including two-stroke motors found in chainsaws, snowmobiles, dirt bikes, and certain water pumps. Some brands of fuel stabilizer are formulated to be used only with gasoline or diesel fuel, while other brands are dual-purpose. It is important to check the product label to be sure.
The amount of fuel stabilizer to be used depends on the amount of fuel in the tank. The directions on every bottle of stabilizer specify how much to add for a given amount of fuel. The quantities specified are usually small. For instance, a tablespoon or two in a lawnmower or chainsaw gas tank is enough to allow gasoline to burn cleanly even after years of storage. One small bottle of stabilizer is enough to preserve a full tank of fuel in a car or truck.
If you are adding the stabilizer directly to the fuel tank, put the required amount of stabilizer into the less-than-full tank, top off the fuel level, and then start the engine. Allow it to run for about 5 to 10 minutes so the stabilizer gets mixed with the fuel that enters the carburetor or fuel injection system. This will prevent gummy deposits and increase the odds of a quick and easy post-storage startup.

How to add fuel stabilizer
Fuel stabilizers are designed to maintain the quality of stored fuel, keeping it from deteriorating over time. They can be used for all kinds of gasoline and diesel engines, including two-stroke motors. Fuel stabilizers are especially useful if you're planning to store your car for a long period of time or if you don't drive it regularly.
- Check the instructions on the bottle of the fuel stabilizer you have chosen and ensure that it is suitable for your vehicle. The directions on the bottle will tell you the amount of stabilizer required for a given amount of fuel.
- Ensure that your fuel tank contains fresh fuel and that it is about 95% full. Some sources suggest that it is not necessary to have a full tank, but it is generally recommended.
- Pour the required amount of fuel stabilizer into the fuel tank.
- Top off the fuel tank to the maximum level.
- Start the engine and let it run for about 5 minutes. This will ensure that the stabilizer gets distributed throughout the entire fuel system, including the carburetor or fuel injection system.
By following these steps, you can effectively add fuel stabilizer to your car, helping to maintain the quality of the fuel and prevent engine problems.
