9 Best Octane Boosters for Better Performance

(Updated on February 22, 2023)

Octane boosters are fuel additives that you pour into your gas tank to increase the vehicle’s engine performance. These boosters will also allow you to get better fuel economy during normal driving.

Most often, octane boosters are used when a gas station doesn’t have gas with a high enough octane rating for your car. Some people use octane boosters when racing their vehicle on a drag strip or track or when running autocross.

Octane boosters are also used by laypeople who simply want to get the best possible performance out of their engine. This will save them money on gas and keep their engine running smoothly for a long time. Not only that, octane boosters are a great alternative to purchasing premium unleaded gasoline. The boosters can be cheaper and do a better job of preserving your engine than premium fuel does.

Now that you know the benefits of octane boosters, it is time to find out which product is right for you.

Top 9 Best Octane Boosters For Cars or Trucks

1) Klotz Octane Booster

Klotz KL-628 Octane Boosters
  • Increases pump gasoline octane up to 10 numbers

Klotz Octane Booster is an octane booster product that has been on the market for more than 5 decades. Even after all this time, Klotz continues to innovate their octane booster formula so that it can perform better than ever. They do this by perfecting the synthetics of the formula in order to maximize their effect on fuel.

Klotz Octane Booster is a very diverse product which is used by both car lovers and competitors in motorsports. If you have ever been to a race track to watch race car drivers compete, you can be sure they are using an octane booster like this one to go as fast as possible.

Spark plugs will sometimes cause an engine knocking issue. This is where the spark plug does not ignite all the air and fuel mixture in the combustion cylinders. There may even be pings that occur during the pre-ignition phase.

When you experience these issues, you will want to use the Klotz Octane Booster because it will work to stop both the preignition pings and the knocking. That is what this particular octane booster is designed to do.


When you pour the Klotz Octane Booster into your fuel tank, it can provide a 10-number increase to the octane rating of your fuel. This is good news for people who want to maximize their engine power while having good fuel efficiency at the same time.

Furthermore, the octane booster will provide the upper cylinders with the proper lubrication they need to ensure the combustion process goes smoothly. This is truly a lubricating agent that will benefit your vehicle immensely.

One bottle of Klotz Octane Booster provides a whopping 1 gallon of the formula. This is a considerably large bottle in comparison to the size of other octane booster products. Along with its large size, the packaging is compact so that it looks smaller than it really is.

Meanwhile, you are charged a very affordable price for this large amount. If you want to save money, then try out this octane booster because one bottle will last you for a long time.


The biggest downside to the Klotz Octane Booster is that it only works well on vehicles with smaller engines. If you have anything bigger than an economy class car, such as an SUV or small truck, then you won’t find much help from this octane booster. Stick to economy cars or small custom cars like race cars. Some people even use this octane booster on their lawn mower engine too.

Another downside is that it can be difficult to optimize the ratio of fuel to octane booster. It will take a lot of practice using the product before you know how much of the booster to use at any given time. If you want to increase your octane rating by 10, you might need to use a lot of the booster formula just to get there. It depends on how big your engine is.

    • Depends on what the root cause of the knocking is. Bad fuel, maybe. It probably won’t stop knocking if you have an underlying issue; octane boosters aren’t a silver bullet.
