10 Best Octane Boosters – Review 2020


Although octane boosters are optional, car owners prefer using them for the engine capacity. The thing is, the fuel quality varies among different stations. In some cases, the octane rating of gasoline drops over time and is harmful to the engine. That’s where an octane booster comes into play. It’s a unique formula designed to stabilize the fuel inside the engine. 

In this post, you’ll find out why using octane boosters can prolong the lifespan of the vehicle significantly, how they are different from fuel stabilizers. Also, we’ll review the 10 most popular octane boosters on the market to facilitate the choice-making process. 

What is an Octane Booster?

Octane boosters are chemical formulas that aim to increase the efficiency of the engine. They have the highest efficiency when applied to high-compression engines – these sports cars. 

Most octane boosters help prevent knock – the pre-ignition detonation. When there’s no knock, a fuel that’s released into the engine is higher in octane. There are multiple anti-knock additives manufacturers use – the following are the most popular ones:

  • TEL – one of the most powerful anti-knocks on the market. The main concern car owners have with tetraethyl lead is its low environmental friendliness.
  • MMT – this methyl-based alternative is, on the contrary, quite environmentally sustainable and has no risk of damaging the emission mechanism. 
  • Ethanol. Although a powerful octane booster, ethanol increases fuel consumption as well. That’s why the additive is mainly used to boost the octane of racing cars fuel and not so much for traditional vehicle models. 

Octane Boosters vs Fuel Stabilizers

If you are a car enthusiast, chances are you’ve heard of fuel stabilizers and could be confused as to how they are different from octane boosters. Let’s break the distinction down. 

A fuel stabilizer is designed to maintain the chemical integrity of the fuel when it’s stored inside the engine for extended time periods – say, for over 30 days. When chemical bonds between fuel particles are broken down or weakened, there are higher odds of contaminants and other harmful particles entering the engine. To preserve the integrity of these bonds, fuel stabilizers are applied. 

An octane booster, on the other hand, ensures gasoline stability under the peak compression of the engine. A solution increases the fuel’s resistance to knocks and detonation. Drivers use octane boosters to ensure timely fuel ignition inside the cylinder. There are numerous claims from manufacturers that octane boosters increase the octane rating of the fuel by a certain number of points – the thing is, a precise difference is hard to deduce.

Benefits of Using Octane Boosters

Octane boosters are a polarizing topic among vehicle owners. While some swear by them and claim impressive octane level increases, others feel like using octane boosters doesn’t make an actual difference. 

Here are some undeniable benefits of boosting the engine with an octane booster:

  • Avoid premature engine detonation. Thanks to octane boosters, fuel particles can blend completely to initiate a smooth combustion process;
  • Less CO2 is emitted. Thanks to octane boosters, there’s more oxygen in the engine, resulting in higher combustion efficiency. Thus, less CO2 is emitted out of the engine. 
  • Higher engine horsepower. Thanks to octane booster,s drivers can enjoy considerably smoother uphill rides. 

How to Apply Octane Boosters?

If you are considering getting an octane booster, be sure you know when (and when not to0 use it and how to apply it to the engine. Here’s a brief list of practical tips car owners will benefit from when handling octane boosters. 

Octane boosters are good for particular engines

Although octane boosters do make a difference in engine efficiency, in some vehicles, it will be much more noticeable than in others. The rule of thumb is, a driver should apply an octane booster only for high-performing vehicles or those that struggle with detonation issues. Checking a default octane level in the car user manual is a smart thing to do before getting an octane booster since there’s a chance you don’t need one at all. 

Decide what type of boost you need

When choosing an octane booster, most drivers are confused when telling octane points and RONs apart. To clear the point up, one RON equals 10 octane points. Basically, for a 3 RON boost, you need a 30-point octane booster. 

How often should an octane booster be used?

The higher the compression of the engine is, the higher the frequency of using octane boosters is. For instance, sports car owners add an octane booster every time they fill the fuel tank. On the other hand, the owners of vehicles with the lower-compression engine only add boosters occasionally – once or twice a month. 

How to add an octane booster to the tank?

Be sure to add a booster to an empty tank. This way, a booster will be able to disperse equally throughout the tank once you pump the gas in. After the tank is full, don’t rush to start the ar. Instead, live the vehicle in a still state for 20-30 minutes and start the engine after this amount of time has passed. 

Top 10 Octane Boosters – Review

There are plenty of octane booster manufacturers who claim to have created the world’s most efficient fuel-boosting solution. Naturally, half of these claims are misleading and unfounded. To make sure you don’t get fooled by a fraud, take a look at the review of the most popular octane boosters on the market.
