Octane boosters are additives used in fuels to increase the octane rating, which helps prevent engine knocking. Knocking occurs when fuel ignites prematurely in the engine, leading to reduced performance and potential damage. By raising the octane level, these boosters allow engines, especially high-performance ones like those in sports cars, to run more smoothly and efficiently. Many drivers use octane boosters to enhance their vehicle's performance, especially in racing or when using premium gasoline. These products come in various forms, including liquids and powders, and can be easily added to the fuel tank. However, it's essential to follow the manufacturer's instructions for the best results.
