What is an Octane Booster?

This is a product that has been made to increase the efficiency of a vehicle engine and to be more specific, aid in fast fuel combustion so that your car can gain speed faster and be able to sustain that speed for a long time. The most important thing to note when looking for an octane booster is to make sure that you know the kind of engine you have to avoid the embarrassment of not getting the result you expected after using it on your car. Basically an octane booster will raise the efficiency of the car by boosting compression to maintain a smooth running engine.​

Octane Boosters: Do They Work?​

To understand how octane boosters work, I will explain what an octane index is. An octane index is a number used as a measure of performance that your fuel has. The higher the octane number (index) the better for you. This simply means that your car is using fuel that is able to withstand high compression rates before going to the combustion chambers.

The octane index is highly affected by the quality of fuel used. The presence of impurities on the fuel will affect the fuel octane levels such that if you use an octane booster can lead to an engine knock and possible low performance. Some octane boosters have fuel stabilizers that promise to keep fuel octane index stable for longer.

By default an octane booster is supposed to realise the octane levels in the fuel you are using, but the rate of success is highly dependent on the type of product you buy and to some extent thief king of engine that your car is running on.

There are other factors that I would like to highlight in relation as to whether an octane booster works or not.

Some old vehicles and those probably still using the carburetor engine will not give any difference whether you use the best octane booster or not.

If you have a supercharged engine that has been specially designed to run on high octane fuel will definitely give you the positive results you are looking for.​

How Much Octane Should One Use?​

This is a question that I felt need to be addressed. We at least have a rough idea of how much fuel or oil is needed to maintain the car at a given optimum. The amount of octane you need is highly dependent on the type of octane booster, the quantity of fuel to be ‘boosted’, and of course the source of fuel you are using. Many manufacturers have placed the recommended number of times you can use their respective products. But I always recommend getting such advice from a certified mechanic who at least knows the history of your car.​

NOTE: An octane booster will work to improve the general performance of your car, therefore, you will only see the results after several treatments which goes back to the point of type of fuel used and the octane level.

You don’t have to worry if you don’t own a modern high speed car, there is still room for improvement to make your car run more aggressively if you can get the best octane booster. That is why we have this guide that will take you through the steps that will help you make the right decision.​

What to Look For When Choosing the Best Octane Booster​

1. Performance​

The most determinant factor on any octane booster product is its boosting capability. The selling point of this product is its ability to boost your engine efficiency. When you look at advertisements, they use the point system to sell the product. You may have come across one that promises 40 points, what it is simply means is that you will get 4 octane levels because the point system states that 10 points is equal to 1 octane level. It is also good to note that some octane boosters will boost better than others.​

2. The Cost​

The cost will determine the type of octane booster that you will opt for. If you are using a heavy duty engine, the cost of your octane needs may be higher. Depending on the type of fuel you use, you may also spend considerate amount of money trying to get your car’s octane level to its normal levels.

3. Do not Believe Everything Said on Advertisements​

The big promises from the product manufacturers do tell you that the highest octane value you can get from any product in the market is 5% more and that the average is 3% more. Anything more than 5% or less than 3% is not painting the correct picture.

4. No Super Performance​

An octane booster is supposed to better performance based on the type of fuel used and the engine you are running on. The notable thing will be the fuel economy and smooth engine operations.

5. Compatibility​

Different engines need specific products to enhance their performances. Some will use universal products to achieve the same. If your car has a low performance engine and you do not go beyond the speed limits quite often, then you do not need an octane booster. But if you are running a super charged high performance engine, you need an octane booster. The bottom line is, the higher the octane value of your engine or fuel, the more octane boosters you will need to maintain its levels.

6. Additives​

Some octane boosters have the capacity to maintain the standards of your fuel’s octane index to acceptable levels for a long time. They use what is referred to as a fuel stabilizers. This kind of product is the most ideal if you have fuel on your tank stay longer because of low usage.​
