stp octane booster

All engines are tuned to run on a specified octane level of gasoline. But what if the gasoline is not so good, an octane booster will come in handy in that situation.

In this Article, we showcase the 7 best octane boosters in the market today, in addition to answering some FAQs regarding the topic.

What Does Octane Booster Do To My Car?

The most common use of an octane booster is to improve driving performance. It does so by raising the octane rating, which is related to the fuel’s stability and the pressure at which the fuel will explode inside the chamber.

Moreover, it can increase the vehicle’s efficiency with specific engines, Hence better fuel economy.

Octane boosters can solve some problems as well, such as engine knocking which is generated by a knock detonation or pre-ignition as they tend to have additives to protect the engine from such problems.

In addition to cleaning the fuel system up to the ignition chamber, when your fuel octane increases and compression happens at a higher temperature and pressure, carbon residue tend to be loosened and blown out of the exhaust.

Also, some products are mixed with special formula additives that help clean your car’s fuel system.

Does Octane Booster Work?

So octane boosters do wonders, but do they actually work? In most cases indeed it works by raising the octane level, therefore raising the performance and efficiency but It is greatly dependent on the vehicle and the engine itself.

Many OEM performance engines are built to make the most of higher-grade fuels like 93 octane. Nonetheless, if you already using the 93 octane fuel you might not see as much of a difference.

However, if you don’t have access to a good-grade octane fuel, then using an octane booster can noticeably increase performance, to add it’s a win-win situation since it improves engine safety by lowering the possibility of knocking.

How To Use Octane Boosters Correctly?

First hand before adding or using any type of additives to your car, we always recommend checking your owner’s manual in addition to reading the specific product guidelines.

Picking up the correct size booster depends on your fuel tank volume, for example, an entire 5.25oz Bottle can treat up to around 15 gallons of fuel, and an entire 15oz Bottle can treat up to around 25 gallons of fuel.

Regarding the octane level, it depends as well on your engine requirement and how bad the fuel is available at the pump.

Now comes the part where you pour your booster into the fuel tank, make sure to put some fuel in first in case you were running on an empty tank then add your octane booster, after that, you should fill up ur tank with fuel. That ensures the product is mixed well with your fuel for optimum performance.

If you have bought a bigger size bottle than you needed, we recommend using it within a year as octane boosters tend to go bad with time. Especially if haven’t been stored in proper conditions.
