What is a fuel stabiliser? Unlock long term fuel protection.

When considering the longevity of your engine, one area that is often overlooked is the use of a fuel stabiliser to prevent the degradation of fuel over time.

Fuel stabilisers, such as Sta-bil Fuel Stabilizer, are known to inhibit the oxidation of fuel and the degradation of fuel components which occur naturally during fuel storage.

Petrol engines will benefit from the use of a chemical fuel stabiliser additive in a variety of ways.

What are the benefits of using a fuel stabiliser?

From storage of the fuel itself, the engine life there are many benefits to making use of a fuel stabiliser.

Preserving your fuel

With the seemingly unending rising costs of fuel, fuel preservation is very much at the top of the list for many people.

Sta-bil Fuel Stabilizer prevents both oxidisation of the fuel and breakdown of molecules which preserves the fuel’s quality and prevents harmful deposits building up within the stored fuel.

The fuel remains in quality condition even when it has been stored for a long time.

Carburettor and System Protection

Fuel stabilizers help keep build up within the engine’s system to a minimum by reducing the formation of deposits that could otherwise stop your engine running efficiently.

This helps prevent corrosion and damage within the system, keeping your fuel lines, injectors, and carburettor safe from harm that can come from the long-term storage of fuel.

Engine Start Up

Deteriorating fuel can also cause issues in the system upon engine start up especially when fuel has been stored for a long time. By using a fuel stabiliser, you are maintaining fuel quality and reducing the need for excessive priming of thew system of cranking which puts additional pressure on your system in the long run.

Long Term Storage

If your engine will not be used for a while, stabilisers will help make sure that the fuel remains protected against degradation during extended periods of inactivity.

For example, if you have a recreational vehicle that you will store for the winter, fuel stabilisers are an ideal choice for protecting the vehicle from fuel degradation and the resulting impacts on your engine.


Fuel stabilisers are not for use on already degraded fuel. They do not “repair” fuel but rather prevent degradation, so they should always be used with fresh clean fuel before storage.

What vehicles are suitable for fuel stabiliser?

Sta-bil Fuel Stabilizer is often used with:

  • Classic collector cars
  • Vehicles in storage
  • Generators
  • Lawnmowers
  • Classic motorcycles
  • Stored motorbikes
  • Other garden/ outside appliances such as snow blowers and leaf blowers

Sta-bil Fuel Stabilizer

Sta-bil Fuel Stabilizer is ideal for both 2 stroke and 4 stroke petrol engines and eliminates the need to drain fuel prior to storage.

Prolong engine life, this best-selling fuel stabiliser protects from a host of risks associated with fuel storage such as the risk of ethanol damage; and the risks associated with gum build up, varnish deposits and rust deposits.

In addition, Sta-bil also removes water to prevent corrosion within the engine, and simultaneously cleans carburettors and fuel injectors. Sta-bil will keep fuel “fresh” for up to 24 months.
