One of the first convenient results of using the octane booster comes with the cleaner fuel burn. This has been noted by a number of drivers. Of course, the cleaner burn is also what leads to fewer emissions. For most drivers, it is advisable to simply add the booster in order to reduce their impact on the environment, especially when driving on long commutes.

Made to offer an extra boost compared to other vehicles, the booster is used for pining as well. Pining can occur in high mileage vehicles as well as in newer vehicles. However, this sound problem can be eliminated with the octane booster. No knocking is heard even in hot weather, which means the octane booster really works.

Since it has a versatile formulation, the octane booster is suitable for various types of vehicles. It works with fuel injected vehicles as well as with carbureted engines. The manufacturer also claims the booster is 3 times more efficient than its alternatives. Of course, this might depend on the type of vehicle but the efficiency of the booster has already been proven. Drivers should also know that if their vehicles have been running on low octane gas for a long period of time, it may take a full refill to see the results they want.

Verdict
With high efficiency, the octane booster is mainly recommended for clean fuel burn and reduced pinging.

Pros
  • Made with a proven formula
  • Reduces fuel emissions
  • Improves pinging

Guide to Buying the Best Octane Boosters

For the best octane boosters, drivers need to look at a few characteristics. Of course, there is a tendency to make them as complex as possible at the moment. For example, if the add to the octane number, they can also be made with additives which clean injectors. So using octane boosters can be one of the small steps taken in the direction of better engine maintenance.

Results in octane boosting
The actual number of octane boost differs from product to product. It also depends on the volume of gas it is added in. If a standard tank comes with 91 octane gas, it can be boosted up to 98 octane levels. But at the same time, there are other products which are suitable for performance vehicles. In this case, they can come with an octane level as high as 105.

The octane boosting results also depend on the type of gas which is put in the car. But most drivers actually use octane boosters on lower octane fuel, in order to save more over time. Testing the actual octane boosting results might not be too easy for the average driver. But there is a simple test driver can use to determine the improvements. Pinging is one of the main areas where an immediate difference should be heard with a higher octane fuel. This is why most drivers should actually listen to their engine and then be able to say if a product is working or not.

Mileage benefits
The mileage benefits of the octane booster are still debated. However, many drivers say they are able to see better mileage with their products, even if just to a small degree. But since the engine is optimized to work in normal parameters, mileage should also improve.

Of course, there are many other variables to mileage improvements. One of them is the actual weight load in the car, which can be higher when there is a full tank of gas. Another variable comes with the tire pressure, which still needs to be the same as it was before adding the octane booster in order to make an accurate assessment of a product.

Improved acceleration
Acceleration is among the first to improve as a result of an octane booster. Most users have the freedom to test this out themselves. Of course, the improvement is only going to be in the normal acceleration parameters of the car and they are not going to make the car have more horsepower or torque than it actually has.

Apart from actual acceleration improvements, drivers should still be able to hear a difference when the car is gaining speed. The motor should not be as loud when accelerating. The good news is that this can be tested out immediately.

Benefits to pinging
Pining is one of the main problems drivers consider octane boosters for. Nearly all cars are actually suffering from this mild issue with low octane gas. This is why it’s actually a good idea to see which products eliminate pinging. If some octane boosters can diminish pinging, the best octane boosters can completely eliminate the issue, in the same way in which high octane gas would.

Cleaning the fuel injector system
The best octane booster should also have the capacity to clean the fuel injector system. It is one of the first ways in which a formula is able to take care of the car. Unfortunately, there is no simple way to tell if cleaning is actually happening inside the injectors. What is clear is that some of the best octane boosters are actually made to act molecule by molecule, ensuring that any residue build-up toe to low octane gas use is eliminated.

Racing vs. standard engines
Not all engines are the same. If standard street cars use a type of octane which can be purchased in most gas stations, not the same can be said about racing cars. This is why it can be interesting to see how racing enthusiasts can benefit from an extra helping hand offered by performance octane boosters. As seen in the examples above, they can take good fuel to a 105 octane level. This is why it can be one of the products aimed at maximizing the full potential of a racing engine, which is more important than with a standard engine, especially from the perspective of acceleration and fuel economy. Pinging might not be as important with these engines.

Price compared to high octane gas
The main benefit of adding octane boosters comes with the lower fuel price. If the price of the booster adds to the price of the regular fuel and leads to a final price higher than that of high octane gas, it simply defeats its purpose. This is why all drivers should make calculations and see if it’s truly worth using octane boosters. The good news is that with most octane boosters, the saving can be considerable over the years.

Final considerations

Some of the best octane boosters are now made to offer a versatility which goes beyond fuel efficiency. They can help prolong the life of the engine or of the fuel injection system. Octane boosters are also among the most interesting choices for those seeking the ultimate level of engine performance. As fuel is one of the true driver-influenced choices for the performance of the car, together with engine oil, it is important to find the right products to make the car run in its normal parameters.

Testing out products is requires to see their efficiency. Apart from enjoying a quieter engine, drivers should also see benefits in the way the car runs, although this is not mandatory. One of the areas where improvements are seen is with acceleration. Furthermore, drivers should also be able to find their own ratio of octane booster to fuel level, as there could be a few small differences to the manufacturer-recommended ratios. Testing out different levels of octane booster is the simplest way to achieve this.
