Octane booster is a fuel additive that is added to gasoline to increase its octane rating. It is used to improve engine performance, reduce engine knock, and prevent damage to the engine caused by pre-ignition or detonation. Octane boosters are often used in high-performance engines, and they come in different forms such as liquids, tablets, and powders. They contain chemical compounds that increase the octane level of gasoline when added in the right amount.

Engines with high compression ratios and high-performance engines often require higher octane fuels to prevent engine knocking, which can cause damage to the engine. Octane booster is a cost-effective way to increase the octane rating of gasoline, which improves fuel efficiency, and provides better engine performance. It is useful for racing, high-performance cars, and also regular vehicles that require higher octane fuels to achieve the best possible performance.
