Introduction To Top 5 Best Octane Boosters

Everything that you put into your vehicle will have an effect on what is happening inside of it – that includes an octane booster, which helps in increasing the octane number of your engine. The higher the octane number, the more compression the fuel can withstand before detonating.

A handful of octane boosters can really make a difference. This guide will show exactly which ones they are.

A handful of octane boosters can really make a difference. This guide will show exactly which ones they are.

This is a very common thing with premium vehicles such as BMW’s, Mercedes, some Nissans, and a whole bunch of other above average vehicles. In some instances, using an octane booster is necessary to make the internal combustion process flow smoothly.

Whether you are using an octane booster for racing purposes, or simply to boost up your current vehicle ratings to help eliminate some internal carbon build-up, we’ve put together a list of the best octane boosters that are currently available for the public to purchase. While there’s a few dozen brands advertising “10,20,30, 40, etc, number boost” that sounds impressive, once you narrow it down, you will realise that these numbers only mean 1,2, 3, maybe 4 octane levels of boost.The products recommended below are proven to work in boosting current octane levels (by various levels) – no compromises here. Take a look…

5 Best Octane Boosters To Buy On The Market Today 2020

NOTE:Octane boosters may advertise boosting your octane levels using a “points system”. 10 points is 1 octane level, so if there’s an advertisement of a boost of up to 50 points, it means 5 octane levels (e.g. 87 to 92 octane). That’s just an example.

If you’ve ever wondered “do octane boosters work, at all?” The answer is yes. See below the top performers.

Main Considerations For Our Top Rated Octane Boosters


Looking at a given octane booster, you’re looking at one MAJOR aspect, and that is by how much it could boost your octane level. Being the most important factor of any octane boosting product, for each recommended product we’ve listed the true level of octane boosting you’ll be able to achieve.
Keep in mind what we said about the points system (10 points is 1 octane level).


Octane boosters can add up quickly when using them for heavy duty applications – whether you are racing, or simply getting your current vehicle’s octane level where it’s supposed to be. The cost associated with using each octane booster is taken into consideration, and is a big factor in whether you should or should not make the purchase.


Torco Octane Booster Accelerator

Toro, is the best octane booster you can get your hands on right now that actually boosts octane number. Ideally used for racing applications, it can also be used by practically anyone else. You have the ability to customise the blend of this booster with your fuel, and raise the octane rating up to 105 octane (if desired).
It’s a very concentrated blend, and for performance oriented vehicles, it is perfect.

Looking at Klutz Octane Booster, you’ll see that it comes in a one-gallon jug. It is designed as a concentrated tetraethyl lead substitute to reduce pre-ignition ‘ping’ and spark knock caused by low-octane fuel. Spark plugs usually fire better due to increased octane levels.
Based on how much you’re willing to use, Klutz octane boost is capable of boosting the octane level by a whopping 10 numbers (100 points). Along with octane boosting, it also provides upper cylinder lubrication.

Along with octane boosting, it also provides upper cylinder lubrication.

Royal Purple’s background is in automotive racing. Whether it is Nascar, drag racing, Formula Drift, etc… you’ll find them as a sponsor in one way or another. As a premium brand, their full synthetic motor oils, as well as other lubricants have proven to withstand extreme conditions.
With their Max-Boost octane booster and stabilizer, you’re capable of bumping your fuel’s current level up by 30 points (or about 3 octane numbers). Some power can be restored, while some engine knocking/pinging can be either reduced or eliminated completely.

A more traditional octane booster is the Lucas-Oil A-Real Octane Booster. This product comes in a 16 oz bottle, which is enough for a single average-sized tank.
It primarily uses a chemical called MMT (Methylcyclopentadienyl Manganese Tricarbonyl)to make the fuel denser and burn slightly longer (giving you additional torque that simply higher octane could not achieve).
Marginal octane boosting can be experienced when full dosage is used.

104+ Octane booster is not to be misunderstood with 104 octane boosting. This product is the last recommended octane booster, but a decent one nonetheless.
More of a fuel injector cleaner than anything else, it can give a marginal boost in power, improve fuel economy due to some carbon build-up fighting properties, and even reduce knocks, pings and throttle hesitation.
In most cases, more than one full dose may be required to experience noticeable differences.
You can treat up to 18 gallons of fuel for every 16 oz of 104+.


Torco is the most expensive octane booster on our list. Costing around 23 dollars for a 32 oz bottle. While it may be pricey, it makes up for it by delivering what it’s meant to – boost octane. It is manufactured in the United States, so you know it is of higher quality.

Looking at the cost, you may get repelled. 50 dollars for an octane booster may seem absurd, but when you look at the quantity and the sheer fact that you can boost your octane level by up to 10 numbers, it becomes worth it.
One whole gallon of a potent octane booster, plus a reasonable price make it worth it. For premium vehicle owners and race car drivers, Klotz can help.

When it comes down to sheer cost of an average serving, Royal Purple’s Max-Boost does not cost much at all. About 11-12 dollars gets you 16 oz, compared to the Klotz and Torco ones mentioned above costing 20-50 dollars.
Though those products are much better, per serving you are paying less here.

Lucas-Oil octane booster does not cost much for a regular 15 oz bottle. About 12 dollars gets you one full dose which you can start using in your fuel tank. **Buying in BULK of 12, can save you 40 dollars (or about 50%).

The cheapest octane boosting product in our line-up, costing around 7.50 dollars for a single dosage. The good thing about this additive, is the savings you’ll receive when buying in bulk. A pack of 6 will cost around 30 dollars, which is a savings of about 15 dollars.

Best Bang for Your Buck

Considering that there’s about 128 fluid ounces in each gallon, Klotz High-Performance octane booster takes the win for being the best bang for the buck.
Not only is it an effective octane booster for regular and high performance vehicles, but it’s also a MUCH cheaper alternative to even the poor mains team boosters. Purchasing this octane booster is about 50 dollars, but for that ,you’re getting about 128 oz (1 gallon).

With an average quantity of 16 oz and cost of 12 dollars coming from poor mainstream boosters, with Klotz, you’d be paying about 6 dollars for each 16 oz.

Best Octane Booster – Buying Guide

If you have ever looked up any product, then you know that there are so many models and brands available today that choosing the right one can be quite a challenge. With octane boosters, however, there are a few tips that you’d want to keep in mind before deciding on one.Firstly, it’s important to fully assess all the benefits that using octane boosters can have. However, do not expect them to be a kind of magical cure, because it is unrealistic, and does not make up for poor engine maintenance. Instead, think of them as a part of engine maintenance routines. With all the advertisements and companies promising you the moon, it’s very easy to be fooled. You have to temper your expectations and keep them realistic.

Truth be told, octane boosters don’t enhance octane rating by more than 5%. The average increase in RON is around 3%. Even though the numbers might not seem that high, they are high enough to be able to fulfil at least some of the promises of octane boosters, such as the prevention of engine knocking, better throttle reactions, or healthier spark plugs and ignition times.

Another thing that you should keep in mind is that not all of the engines require an octane booster. It is necessary to meet the high-octane fuel engine requirements to keep fuel quality at desired level. Smaller engines with higher revving powers, on the other hand, can do just fine without them.

Benefits of Using Octane Booster

Octanes are measured in RON, which is an abbreviation for Research Octane Number. The modern gasoline engines are designed to be run on a fuel with 91 RON, 95 RON or 98 RON. However, higher octane ranges, such as 100 RON are also present – the thing is, however, that they are mostly needed in high-demand engines, like the ones in race cars and boats, and are not really meant for the passenger cars. Since having a common fuel standard makes things easier for the manufacturers, they adhere to these particular specifications.The problem can arise when the fuel itself has an octane rating is lower than 91 RON – this could happen due to a variety of reasons, from poor production quality in the refinery itself to the presence of contaminants in the barrel used to store the gasoline.

If the imbalance is not checked, then the engine can suffer from something that people refer to as engine knocking, which is caused by low octane level – it happens when the fuel burns unevenly in the engine’s cylinders. As a result, it usually produces tapping and pinging sounds that get louder and faster as you accelerate. Today’s engines, however, are designed to monitor the fuel’s quality, as well as adjust the engine’s management routine to try and combat the onset of knocking.

If such a situation happens in your vehicle, your engine will be performing in a lower-power phase, and will be under stress. Also, there’s the fact that the fuel economy will take a hit as well. This is where the octane boosters will be of biggest benefit. They will lift the RON index of the fuel, and as a result, it will prevent the engine from feeling distressed for want of a higher-grade fuel. What’s more, octane boosters come with many other functionalities, like fuel stabilising, as well as cleaning up of clogged fuel system components.

Essential Factors to Consider With Octane Boosters

Just like with most products, there are some things that you should consider before making your final decision.
When it comes to octane boosters, the first thing is the specific problem that it is intended to solve. Most octane boosters come with a variety of functions, aside from the main one of increasing the octane rating.For instance, some are great cleaning agents, while some allow for a more stable fuel mixture – this helps the fuel to retain its energy stores for extended periods of use. An important factor to consider here is the type of engine that is used – after all, it is the engine that determines the fuel requirements of your car.The next thing to take into consideration is the budget that you have. Even though a lower end booster will probably not serve its purpose, it doesn’t mean that the most expensive octane booster will. Why is that? Well, it comes from the earlier thing that we mentioned – narrowing down the specific requirements. Depending on what you need your octane booster to do, you will be able to accurately assess the price spectrum. An important factor to consider, in this case, would be the frequency with which the octane booster will be used. Usually, they need to be used repeatedly, so things like the packaging size or the quality are also worth taking into account.

The last but not least thing that you should really take into consideration are the reviews of people who already bought the product you are interested in. As we already said, companies will promise you the moon, but oftentimes it turns out that the product is not as great as its advertisement.

That’s why independent reviews are the best source of information – since they are not being paid by the producer of the product, they are able to express their true feelings about it, without unnecessary sugarcoating. Also, it gives you a better understanding of which product would work best for your engine specifications, and the manner in which your car or other vehicle is used- especially since some people claim that driving style can have a significant impact on the octane requirements from the fuel.

How to Use Octane Boosters

The first thing you’d want to do is find out what is the octane level most suitable for your vehicle – you can either check the manual of your vehicle, or look underneath the gas cap. If you don’t meet this level or you exceed it, you might experience underperformance of your car. Choosing the right octane booster is crucial – this is where what we said above about essential factors to consider comes into play.If you already bought one, then you can proceed to figuring out the right mixture. Pour the octane booster into the tank, but not with our checking the back of the bottle for information how much of it you should add. Once you’ve done it, the only thing left to do is adding regular gas.

If you want the product to perform at its best, then you should use it within a year, or at least keep it in good conditions, for example in the original container. Keep in mind that leaving it in the back of your car for a long period of time is not a good idea, which is also why you shouldn’t buy large containers – they might be saving you money at the moment, but the thing with octane boosters is that it’s better to use them as soon as possible.

Octane Boosters – FAQ

We understand that you might have many questions regarding the octane boosters, which is why we decide to answer the most frequently asked ones in this section.

➡️ What are octane boosters?

We said this name so many times already, but what actually are octane boosters? Octane boosters are described as additives that are supposed to enhance the fuel’s octane rating. Even though they might be more effective in sports cars than in regular vehicles, vehicle owners still think of them as worth investing into – mostly because of their ability to multiply power and improve efficiency.

The octane rating indicates the compression that the air / fuel mixture can handle before it spontaneously combusts. Speaking more technically, the octane is actually a hydrocarbon compound in the fuel itself. Highly volatile, the eight hydrocarbon chains make the process involved in the combustion happening in the engine go more smoothly. This has an impact on the acceleration generated, and it provides a measure of knock resistance of the gasoline used.

Several factors influence the octane rating – some of them being spark timing, the engine temperature controls, or engine’s compression ratio. To put it simply, a quicker vehicle needs a higher octane rating than one with a less powerful engine – this is where the octane boosters come into play. Keep in mind that smaller engines might not even need an octane booster.

➡️ Are octane boosters safe?

The answer is yes – the octane boosters are safe. However, keep in mind that they should come with lab-tested formulations.

➡️ Does an octane booster need to be used repeatedly?

The truth is that an octane booster is not something that you use once and get long-lasting benefits and great results. It should be used every time you go to the gas station to fill up the tank. Only this way you will be able to see the best results.

Also, if you are preparing yourself for something that you know will require the maximum engine performance, then you should start using an octane booster weeks before.

➡️ My car is turbocharged. Can I still use an octane booster?

The answer is yes. Every time the engine will benefit from an octane booster, no matter if it’s a turbocharged, aspired or racing engine – they all will do well out of optimum performance, which is something specific to the high octane.

➡️ I have a racing car – will an octane booster help?

Yes, there is no reason why it shouldn’t – octane boosters can be used on engines that have extra horsepower.

➡️ Are octane boosters safe for oxygen sensors?

If the octane booster you buy has a lab-tested formulation, then it should be completely fine to use it on oxygen sensors. What’s more, they should also be fine for fuel injectors or any other mechanical or electric part of the engine.

➡️ How much octane booster should be added to the fuel?

Now, this is something that we cannot really help you with, as the amount of octane booster that needs to be added to the fuel is a rather individual matter for every product. To obtain the results you wish, your best bet would be following the instructions printed on the recipient.

➡️ How does an octane booster affect the engine performance?

The higher octane level the fuel has, the more compression and heat it can handle before detonation. When the compression increases, it gives a bigger explosion within the cylinder, which improves the overall engine performance.

With that being said, we reached the end of our best octane booster buying guide. We hope that it was at least slightly helpful, and allayed some of your doubts.
