Classic cars are often only driven occasionally, and they may be stored for months at a time. This can cause the fuel to deteriorate, which can lead to engine problems. Fuel stabilizers are a chemical additive designed to preserve the quality of gasoline when it is stored for extended periods. They can keep fuel fresh for up to 24 months and prevent engine problems that might reduce fuel efficiency. However, fuel stabilizers are not necessary for all vehicles, and some sources suggest that they are only needed for small engines.

Why fuel stabiliser is important for classic cars
Classic cars are often only driven occasionally, and they may be stored for months at a time. This can cause the fuel to deteriorate and become less potent over time, which can lead to engine problems. This is where fuel stabilisers come in.
Fuel stabilisers are chemical additives designed to preserve the quality of gasoline or other fuels when stored for extended periods. They stop the oxidation process, preventing the breakdown of chemicals in the gas and keeping the fuel fresh and effective for at least two years. This is important for classic cars as it ensures that the fuel will still be usable when the car is taken out of storage.
By adding a fuel stabiliser to the tank, the fuel will stay at full strength and won't gum up the surrounding parts. This means that the car will be ready to drive right out of storage, without the need to clean the carburetor or refill the tank. Fuel stabilisers are suitable for all kinds of gasoline and diesel engines, and they work with both ethanol and non-ethanol fuel types.
To use a fuel stabiliser, simply add it to a full tank of fresh gas and run the engine for about five to ten minutes to ensure it gets distributed throughout the fuel system. It's important to follow the instructions on the product label, as some fuel stabilisers are formulated for specific types of fuel. While a stabiliser can extend the shelf life of gasoline, it won't last indefinitely, and it's recommended to use the stabilised fuel within six to eight months for optimal performance.

How fuel stabiliser works
Fuel stabiliser is a chemical additive designed to preserve the quality of gasoline or other fuels when stored for extended periods. It is meant to keep the fuel from deteriorating over time. When you add fuel stabiliser to the tank, the fuel will remain at full strength and will not clog up the surrounding parts. This is because the fuel stabiliser stops the oxidation process from happening, which means the chemicals in the gas do not break down over time.
Fuel stabilisers are suitable for all kinds of gasoline and diesel engines, including two-stroke and four-stroke motors. They are also compatible with both ethanol and non-ethanol fuel types. One small bottle of stabiliser can preserve a full tank of fuel in a car or truck.
To use a fuel stabiliser, ensure there is fresh gas in the tank and that the tank is about 95% full. Then, pour the stabiliser into the tank and run the engine for about five to ten minutes to ensure it gets distributed throughout the fuel system. The stabiliser will remain in the tank until you start diluting it with new, untreated gas.
It is important to note that fuel stabilisers cannot work miracles. While they can extend the shelf life of gasoline, they do not last indefinitely. Generally, stabilised gasoline can be stored for up to 12 to 24 months, but it is recommended to use it within 6 to 8 months for optimal performance.

When to use fuel stabiliser
Fuel stabilisers are designed to maintain the quality of stored fuel, not necessarily to improve gas mileage. They are meant to keep the fuel from deteriorating over time. Fuel stabilisers are especially important if you have a car that you rarely drive or one that you keep in storage for long periods.
If you drive your car regularly and use up the gas within days or weeks of filling up the tank, the fuel stays fresh. However, if you let the fuel sit in the tank without using it for a few months, it becomes less potent over time and can even start to break down since it has been exposed to a mix of moisture and oxygen while sitting in the tank. This can lead to poor engine performance or, in the worst-case scenario, an engine that fails to start at all.
Fuel stabilisers are chemical additives designed to preserve the quality of gasoline or other fuels when stored for extended periods. They keep fuel fresh and effective for at least two years of storage time. They prevent chemical reactions within stored fuel, as well as the evaporation of some volatile components, which can leave liquid fuels less likely to ignite properly in an engine after more than three months of storage. Fuel stabilisers also prevent gummy deposits from building up in sensitive areas of the motor, which can cause engine problems and reduce fuel efficiency.
To use a fuel stabiliser, make sure there is fresh gas in the tank, and that the tank is about 95% full. Then, pour the fuel stabiliser into the tank and run the engine for about 5-10 minutes to ensure it gets distributed throughout the entire fuel system. The fuel stabiliser will remain effective until you start diluting it with new untreated gas.

How much fuel stabiliser to use
If you own a classic car, you should consider adding a fuel stabilizer to the tank if you don't drive it regularly or plan to store it for an extended period. Fuel stabilizers are designed to maintain the quality of stored fuel and prevent engine problems that might reduce fuel efficiency.
Now, how much fuel stabilizer should you use? Well, it depends on the amount of fuel in your tank. The directions on every bottle of stabilizer specify how much to add for a given amount of fuel. Generally, the quantities specified are small. For example, a tablespoon or two in a lawnmower or chainsaw gas tank is typically enough to allow gasoline to burn cleanly even after years of storage. Similarly, one small bottle of stabilizer is usually enough to preserve a full tank of fuel in a car or truck.
It's important to note that fuel stabilizers are meant to be used with fresh fuel, and it's recommended to keep the gas tank about 95% full to avoid condensation build-up during storage. After adding the stabilizer, be sure to run the engine for around 5 to 10 minutes to ensure that the stabilizer gets distributed throughout the entire fuel system.
By following the instructions on the stabilizer product you choose and running the engine for a few minutes, you can effectively use fuel stabilizers to maintain the quality of fuel in your classic car during storage periods.

How to use fuel stabiliser
Fuel stabilisers are designed to maintain the quality of stored fuel, preventing it from deteriorating over time. They are especially useful for classic cars that are only rarely driven, or those that are kept in storage for long periods of time.
- Check that you have fresh gas in your tank.
- Run your tank to nearly empty.
- Open the fuel tank and measure out the amount of stabiliser recommended by the manufacturer.
- Pour the stabiliser into the tank.
- Top off the tank with fuel.
- Turn on the engine for 5-10 minutes to ensure the stabilised fuel is distributed throughout the fuel system.
The stabiliser will remain in the tank until you dilute it with new, untreated gas. It is important to note that fuel stabilisers are not designed to improve gas mileage, but they can prevent engine problems that may reduce fuel efficiency.

Frequently asked questions
Fuel stabilizers are designed to maintain the quality of stored fuel, preventing it from deteriorating over time. This is especially important if you plan to store your classic car for an extended period, as the fuel can break down due to exposure to moisture and oxygen. By adding a fuel stabilizer, you can keep the fuel fresh and effective, ensuring that your car will start and run smoothly when you take it out of storage.
First, ensure you have fresh gas in your tank and that it is about 95% full. Then, pour the fuel stabilizer into the tank according to the directions on the bottle, which will specify the amount required for the volume of fuel. Finally, run the engine for around 5-10 minutes to allow the stabilizer to distribute throughout the fuel system.
It is recommended to add a fuel stabilizer every time the fuel in the tank is replaced or cycled. Stabilized gasoline can typically be stored for up to 12 to 24 months, but it is advised to use it within 6 to 8 months for optimal performance.
