Do Fuel Stabilisers Really Work?

Fuel stabilisers exist to keep fuel fresh and prevent serious engine issues caused by ethanol damage. 

But how effective is a fuel stabiliser? In this article we'll address common questions and help you make an informed decision. 

Can you add a fuel stabiliser to a full tank?

One of the most common questions about fuel stabilisers is whether you can add them to a full tank of fuel. The short answer is yes, you can. Fuel stabilisers are designed to mix with your fuel, regardless of whether your tank is full or not.

However, a nearly emptier tank allows for better mixing, as the fuel stabiliser can distribute more evenly throughout the fuel. But, the effectiveness is not significantly affected by how full the fuel tank is.

How long does fuel stabiliser keep fuel fresh?

That largely depends on the product you choose.

Typically, products like Sta-Bil E10 Fuel Stabilizer can keep fuel fresh for up to 12 months. It helps prevent fuel from breaking down and forming gum or varnish deposits that can clog fuel lines and injectors.

The 12-month timeframe is a general guideline, but it's important to consider various factors that can influence the stabiliser's effectiveness.

For example, the storage conditions play a role. If you store your vehicle or equipment in a cool, dry place away from direct sunlight, the fuel stabiliser will be more effective in preserving your fuel.

Do you have to run your engine after adding a fuel stabiliser?

One misconception about fuel stabilisers is that you need to run your engine immediately after adding them, which is not the case.

Fuel stabilisers work by preventing the oxidation and degradation of fuel components, so there's no need to start your engine right away.

However, it's a good idea to run the engine for a few minutes after adding stabiliser to ensure that the treated fuel circulates through the system and reaches all crucial components.

It's especially important to run the engine if you plan on storing your vehicle or equipment for an extended period, as it ensures that the entire fuel system benefits.

Can you over use fuel stabiliser?

It's essential to follow the manufacturer's instructions carefully.

Adding too much stabiliser can potentially result in a less effective mixture and waste product. Sta-Bil E10 Fuel Stabilizer, for example, provides clear guidelines on the proper dosage for various fuel tank sizes, ensuring you get the best results without any risk of overuse.

Overuse is generally not a concern if you stick the recommended guidelines. Using less than the recommended amount can result in insufficient protection for your fuel, so it's essential to strike the right balance.

What's the deal with Sta-Bil fuel stabiliser?

Our fuel additive is designed to combat the challenges posed by E10 fuel, which contains up to 10% ethanol and can lead to corrosion and engine issues if left untreated.

It not only helps keep your fuel fresh for up to 12 months but also contains corrosion inhibitors to protect your engine. It prevents the harmful effects of ethanol damage, such as rust and corrosion in the fuel system.

The unique formulation addresses the specific issues associated with ethanol-blended fuels. Ethanol can absorb moisture from the air, leading to water contamination in your fuel system. This moisture can cause corrosion and disrupt the combustion process in your engine.

In addition to its protective qualities, Sta-Bil E10 Fuel Stabilizer is straightforward to use. Simply follow the dosage recommendations on the product's packaging based on your fuel tank size, and add it to your fuel. It's compatible with all petrol engines, making it a versatile choice for a wide range of vehicles, tools and  equipment.
