Does a Fuel Octane Booster Work?

High-quality octane boosters won’t provide your vehicle with more horsepower.

However, they are beneficial in other ways and can assist you in heightening horsepower with various top-notch performance parts – all without risking overheating the engine. Certain brands and formulas also promise to assist in clean fuel burn procedures and help to stabilize the fuel.

Understanding Octane Boosters

Octane Booster, in a nutshell, comes in the shape of a premium fuel treatment manufactured with the sole purpose of increasing the regular octane rating of standard unleaded 91 (RON) high octane fuel, making sure the fuel in the cylinder ignites, even in high-compression engines.

It has been manufactured to boost generic octane ratings by 2.5 percent. This applies to both gasoline engines and high compression engines.

Do Octane Boosters Work?

Octane boosters, all in all, are fuel enhancement products, and yes, they do work, providing these fuel additives are used correctly.

When done so, octane boosters heighten the fuel octane rating, which boosts a vehicle’s performance, ensuring the fuel tank operates at the optimal level.

In most cases, when you use an octane booster, octane ratings heighten, and pre-ignition is more challenging. This results in higher car performance due to a higher compression ratio.

What Octane Booster Works?

When it comes to the best octane boosters on the market, this comes down to several factors – how you drive your vehicle, the make and model, its age, the fuel system components, and personal preference.

Some of the most prevalent octane boosters available comprise STP octane Booster, Lucas Oil Octane Booster, Torco Unleaded Fuel Accelerator, Klotz Octane Booster, and Royal Purple Max Boost, to name a few.

The are other octane boosters on the market. To ensure you choose the correct one, it is important to do your research and go off recommendations.

Does An Octane Booster Help Gas Mileage?

Yes, providing you choose the correct octane booster and one with an additive that heightens octane and lowers the likelihood of pinging, knocks, and hesitation while also assisting in cleaning the fuel system on the whole.

By regularly adding a quality Octane Booster to your fuel tank or fuel intake system, you will heighten fuel mileage and engine performance.

When Should You Use An Octane Booster?

The answer to this question is only when you need to! You would necessitate an octane booster when you experience the engine ping or knock. It is important to note that an octane booster(no matter how high the quality) won’t heighten your car’s torque, horsepower, or speed.

However, it will encourage your car’s engine to function accurately without causing any harm to itself. One key tip? Never mix octane boosters, as this won’t help increase your vehicle’s peak performance or fuel economy.

Fuel Octane Booster Pros And Cons

There are many pros and a few cons to using boosters, varying from heightening horsepower through the correct use of components to cleaning fuel storage units. We have listed a handful of these pros and cons below: 


  • A boost in efficiency and power. High-quality octane fuel burns at a much better rate during combustion
  • Ensures all components run well. If your engine runs well, this will keep components such as catalytic converters happy! This, in turn, will help to restore lost horsepower.
  • Cleans your engine. Specific boosters boast of cleaning your car’s fuel tank! 


  • Too much additive can clog up components, including the likes of spark plugs and oxygen sensors. It is important to read the label carefully before adding an additive such as this one to your fuel-injected system or cap-less gas system.
  • It can be expensive to invest in most octane boosters, especially on top of the cost of low octane gasoline and higher octane gasoline. This is especially the case if your fuel consumption is high.

Advantages of using fuel octane boosters

There are many advantages to octane boosting products. As well as the most popular benefit – to heighten driving performance – they are also renowned for engine function improvement.

On top of this, a handful of high-quality boosters can also assist in heightening the function of the engine.

Octane booster side effects

As with all things, too much of something is never good. If you add more octane to your fuel than necessitated, your engine will perform at a slow or even sluggish speed.

This is down to the fact the fuel will be burning at a too slow a rate. An octane boost is a gasoline engine additive and, therefore, should be used to heighten the octane rating, not lower it. The booster will stop knocks and pings from occurring in your vehicle’s engine.

So, Is It Ok To Use An Octane Booster?

Yes, it is perfectly ok to use an octane booster. However, it is recommended that you opt for a higher octane fuel before investing in an octane booster.

If you have tried this and your engine is still showcasing signs of pinging and knocking, this is when a quality octane booster will come in extremely handy as it boosts the octane.

The majority of boosters have been fashioned to lower the rate of pre-detonation by stopping pinging and knocking from taking place.

Those with contemporary car models may notice that they require higher levels of octane. Why? Inserting fuel that is under 91 RON will often cause unwanted issues. This is mainly because many fuels today contain contaminants and are often lower quality overall lower – even if the gas station has specified otherwise.

Lengthy exposure to low-grade fuel can lead to more detrimental issues in the future, particularly with the engine.

Can An Octane Booster Damage An Engine?

Simply put, no. Octane boosters increase your vehicle’s octane rating and your engine life span. The ultimate purpose of quality boosters is to remove the possibility of engine damage, which makes them safe to use.

Correctly using quality boosters won’t harm your car’s engine. However, overuse of this fuel additive can cause damage to your vehicle’s components, such as the spark plugs or the internal combustion engine.

How Long Does An Octane Booster Last?

In terms of shelf life, the majority of high-end octane boosters last a total of two years. However, they must be stored in the correct environment. This should be a cool area, such as a dark garage or a cupboard.

On top of this, fuel stabilizers such as Boostane Professional Octane Booster should be sealed correctly. If you have already opened the product, you must reseal it properly.

Most companies recommend using octane booster regularly and within 12 months. Why? The performance will falter over time, especially if left sitting for lengthy periods. This is especially the case for supercharged vehicles that use racing fuels.

Choosing The Best Octane Booster For Your Car

This will depend on the type of car you own, how the car is maintained and how you drive it. For example, if you own a car that necessitates racing fuel, you will need to invest in an octane boost racing formula. If not, you may harm the fuel injectors or oxygen sensors.

The same goes for cars that require unleaded gasoline and high-performance vehicle types with carburetor engines.

For best results, always read the label on the fuel stabilizer and always use premium gasoline instead of reformulated gasoline. This will help to stabilize fuel and prevent engine detonation.
