Why You Should Invest In the Best Octane Booster?

Octane booster

The use of an octane booster is not compulsory but is a must for engines requiring higher compression ratios, supercharging or turbocharging. Below are some of the best reasons why you need a fuel additive.

Higher Octane Rating

Literally, the main benefit of this fuel additive is to increase the low octane rating of regular-grade fuels in pump stations. In the industry, octane rating is expressed in Research Octane Number (RON).

The RON of a regular grade fuel is 87. Adding an octane booster can increase it by 3 to 5 points depending on the quality of the additive.

Reduced Engine Knocking and Pinging

By increasing the octane rating, you can prevent engine knocking and pinging by premature detonation. The fuel and oxygen must have enough time to blend completely before combustion.

Knocking and pinging lower the overall performance of the engine and hastens its wearing.

Clean Fuel Systems

Most fuel additives in the markets are incorporated with a chemical that can dissolve solid deposits clogging up inside fuel injectors. Using these products will help you clean the internal systems of your engine.

Increased Horsepower

There will be instances where you need to carry heavy loads, drag trailers, go uphill or drive on hot summer days. For your car to survive these harsh conditions, it must have sufficient horsepower to move forward. Using an octane booster can be one of your best options for this requirement.

Fuel Efficiency and Reduced CO2 Emissions

Upon increasing the octane rating you are also increasing the power generated per volume of fuel. Consequently, you get more energy from each volume thereby consuming less fuel.

Likewise, the presence of an additive enhances the fuel and oxygen mixture which results in better combustion. Complete combustion of fuel results to lesser production of unburned fuel and carbon footprints.

What Makes The Best Octane Booster?

STP Octane Booster

Before making any hasty decision, here are some of the important factors you need to look for in buying the best octane booster for best engine performance.

Engine Compatibility

You need to check on the product label of the booster and the engine specifications of your car. If the octane rating of the booster is lower than what is required for the engine, it results to lower performance and risk of wearing.

Octane rating points

The main factor for measuring the performance of a fuel additive is how many points it can add to the existing rating of your fuel. Typically, most boosters can add rating points between 2 to 5.

Volume and Dilution

For practicality sake, if buying a larger volume or in bulk could give you more savings, then go for it. Buying in retail is only good if you are still trying out the product. Likewise, you can always test varying ratios between additive and fuel to get the most cost-efficient mixture.


Most of our purchasing decisions are dictated by the price of the product we want to buy. However, if the cost varies little compared to the better quality, then choose to pay for quality.

Saving a few bucks while compromising quality and engine condition is never practical.

Frequently Asked Questions

For more information, we have included some FAQs relevant to our topic.

What does octane rating mean?

This refers to the fuel’s capacity in mitigating the occurrence of engine knocking and pinging due to premature detonation of the fuel. In pump stations, you can see the octane rating on those yellow backgrounds that are written in black numbers.

What happens if I use a lower octane rating specified for my engine?

There will be low engine performance for such action and it elevates the risk for knocking and pinging. If done frequently, it can damage the entire engine and can compromise its warranty service.

Is it worth it to buy octane boosters?

If your engine requires high compression ratios or uses turbocharging, then buying an octane booster is more cost-efficient than buying premium high-grade gasoline. The average retail price difference between regular and premium grade gasoline has doubled – $0.25/gal to $0.50/gal.

Moreover, the reduced fuel consumption and minimal carbon footprints from your vehicle add up to its overall benefits.

Why some car engines require high octane fuel?

Fuel with high octane rating is commonly used for engines requiring high compression ratios or which uses turbocharging or supercharging. These types of engines draw more oxygen into the cylinder which allows more energy extraction from combustion.

However, to prevent any premature detonation your fuel must have a high octane rating to compensate with elevated pressure.

Where does 85 octane rating fuel typically sell?

This type of fuel is tolerable for carbureted engines and is commonly sold in places at higher altitudes because of the lower atmospheric pressure. Using this type of fuel for modern vehicles is not completely suitable as there are recommended octane ratings specified for those models.

What fuel stabilizers do?

There will be instances when your car will be unused for a month or more and it has a few liters of fuel left in the tank. The idle fuel in the tank eventually decomposes to various components of hydrocarbons.

In this situation, there is a higher risk of contamination and alter quality. To prevent the decomposition of your fuel, you need to add a fuel stabilizer to keep it in good shape.

When is the best time for using octane boosters and fuel stabilizers?

Fuel stabilizers are added into your fuel before storing and not using your vehicle for a period longer than 30 days. Meanwhile, octane boosters are preferably used every time you gas up. The more frequent you will be using octane boosters, the better will be the performance of your engine.


Based on our comparisons and reviews, we highly recommend Lucas Oil Octane Booster as our top choice for this list. For a minimal investment, it allows you higher efficiency as one full bottle can be mix with 25 gallons of fuel. Moreover, it raises your octane rating by 3 points, so if you are using 91 octane then it becomes 94 octane.

Another benefit worth praising of Lucas Oils is that it is compatible with catalytic converters and oxygen sensors. It also contains ingredients that help clean the internal system of your engine. If you have an old vehicle, this one can completely supplement its lost power which is useful for harsh driving conditions.

Nevertheless, the final decision of choosing which one is the best booster totally rests upon you. Hopefully, we have given you worthwhile information that will help you in the choosing process. If you find this article useful, kindly share it with your friends or colleagues.
