As an octane booster, its main job is to boost these points. But, this one by LUCAS was designed to offer much more than just that.

By applying its contents to the fuel, you’re also making sure to produce fewer emissions, and there’s no need to mention the benefits from this.

Best Unleaded Fuel Accelerator

  • 32 Ounces
  • Unleaded
  • Safe to Use
  • High-Octane

Our second pick is one by TORCO. They describe their fuel accelerator as one of the best out there, even coming close to resemble race fuel. You’ll be the one to decide whether that’s an accurate description, so wait until you see the specs of this amazing octane booster.

First, let’s talk about octane points. By using the entire 32-ounce can with 10 gallons of gas, you can get your fuel octane points to rise up to 102. If you use the whole can with 5 gallons of gas, you can get an exceptional result standing at 105 octanes. These are nothing if not pretty remarkable results.

Regarding price, which is another essential factor in buying, well, almost anything, this amazing octane booster comes at a relatively reasonable price. It’s not extremely budget-friendly, it’s not among the cheapest out there, but it’s also not the most expensive, as well. If it meets your budget, then you won’t go wrong by choosing this one by TORCO.

RaceGas Race Fuel Concentrate

Best Off-Road Use Octane Booster

  • 32 Ounces
  • Powerful
  • Raises Pump Gas up to 105 Octane
  • Patented Unleaded Formula

RaceGas is another brand definitely worth mentioning when it comes to finding the best octane booster out there. This is another 32-ounce package that might prove to be even more robust than the previous one, but it does come with a few of its own drawbacks as well.

One of the best things about it is that you will only need around two ounces to raise the octane of your fuel by up to 40 points. Now, if you do apply more than the recommended amount, there is a risk of activating the oxygen sensors. You should be fine if you follow the instructions.

It is powerful, there’s no doubt about that. It has been tested on powerful machines such as race cars, drag cars, rally cars, snowmobiles, boats, and more. However, another important detail you might need to know is that this octane booster is recommended for off-road use only. This can either be a pro or a con, considering what you’re looking for.

How to Choose an Octane Booster

Now that you’ve finished seeing our top picks for some of the best octane boosters out there, it’s time to see what our buyer’s guide has to say. This is intended to help you find the best one for you and make sure you buy something that will satisfy your needs, and make sure your car runs with peak performance.

So, there are a few essential things to learn when purchasing an excellent octane booster for your vehicle. We will discuss what they are here and make sure you are prepared for buying.


One of the most essential and obvious things you will initially need to be on the lookout for is how much power the octane booster can provide. This can be measured in octane points. The typical octane levels in fuel are usually around 87 points, which is perfectly normal. The scale moves up to mid-grade standards as the points rise to anything between 88 and 90. The final measurement is known as premium, which is anything between 91 and 94 octane points.

The best octane boosters out there will make sure to raise your octane levels slightly higher than that, making sure to reduce pinging or knocking. The higher the points, the less pinging and knocking you will experience, and the faster and better the engine starts and works. This is among the most important features to look for, so focus on this before getting hooked on extra benefits like fuel stabilizers present inside and anything similar.


The next thing you need to pay attention to is something known as compatibility. Even the best octane booster on the planet won’t do you any good if it’s not compatible with your vehicle. There are some that are specific vehicle types, meaning they only work on what they’re intended for. There are also universal ones, meaning they will work on almost anything. These features can have certain drawbacks that may include efficiency, cost, and similar.

The best thing to do here is to check before you buy. If you find that it’s compatible with your vehicle, then, by all means, go ahead and get your new octane booster. Compatibility is something never to take for granted as it’s something that can cost if overlooked. It’s similar to additives that are designed for specific engines, such as diesel fuel additives and petrol ones in particular. Make sure you check, and then go ahead and buy.


Before you get confused about this one, let’s elaborate as simply as we can. When this comes up, what we’re trying to say is to consider how much of the product you’re going to need to treat a certain amount of gas. For example, if you plan to treat a 25-gallon gas tank, how many ounces of the octane booster in question will you need to pour to be satisfied with the results?

Hopefully, you can understand what we’re trying to say, as not all octane boosters treat the same amount of gas. Some are more cost-efficient, meaning fewer ounces of octane booster will treat more gallons of gas and vice versa. We felt that it was necessary to keep this in mind as it highly affects the next thing we’re about to talk about.


We all know that making sure we don’t spend an abnormal amount of money when buying anything should be a priority. The price is something everyone continually considers first, and it’s definitely not wrong to do so. When it comes to choosing the best octane booster, you will generally want to be looking at anything around $30 to $50. Don’t take this too literally, as you should also consider the things we mentioned above, such as how much of the octane booster is needed to treat a certain amount of gas.

Protection and Safety

One of the last things to consider is whether the product you’re getting is safe for your vehicle. You’d be surprised by how much damage something like this can do if not used as recommended and as advised. A few common examples of this can include whether the octane booster you’re considering will affect the O2 sensors or the catalytic converters. This is something you must check before proceeding with the purchase.


These are a few of the basics you must consider before buying. We suggest you don’t focus as much on making sure the octane booster cleans things like fuel intake systems and similar. There are separate products that focus on cleaning the engine and its components, like an engine degreaser. Make sure you think about what we’ve mentioned above, and you should be OK with your purchase.
