Here is a fun video that shows an octane booster in action. Enjoy!

Let us take a quick look at all the factors that need to be considered for picking the right octane booster.

Factors To Consider Before Buying

Just because you don’t own a racing car or don’t regularly participate in the Grand Prix does not mean that your car cannot use this performance booster. It can come pretty handy for cars with powerful engines. The main factors to consider before buying an octane booster are:

Total Octane Boost

So the fuel-air mixture already has the octane compounds present within it. This compound helps in smooth burning of the fuel and hence better and more stable performance. The octane boost rating is the technical specification that refers to the ratio by which the additive can improve the presence of octane compounds without your engine.


We are not encouraging you to go for the costliest brand in the market. But don’t pick the cheapest one either. Do a bit of research and pick the brand that hits just the right spot with respect to the performance and price for you. And don’t shy away from spending a few extra bucks within reason on your purchase if it comes with proven benefits.

Customer Reviews

Whether it is a Youtube video or an online product, the comments and reviews are always the most entertaining and often enlightening part of this interaction. You can save a lot of time and money if you just spend a few extra minutes going through the customer review section. This makes the online shopping portals all the more useful even when you are buying something for the very first time. And guess what, we already did all the grinding and prepared this review for you!

Compatibility Ease

The engine that powers your vehicle is not compatible with all kinds of octane boosters out there. It will save you a lot of trouble if you figure out the main types of octane boosters that do wonders to your car. And stay away completely from the ones that make your car behave like an untamed horse.

Usage Frequency

Your lifestyle comes with a cost. With every cent you spend on a particular commodity or service, you are taking away from all other options that you could have opted for. So before you make this transaction, analyze if your driving style will actually benefit from adding this new feature to it. If yes then go for it!

These are the few factors you need to keep in mind to bring home a useful octane booster for your car.
