Octane Booster is a fuel additive designed to increase the octane rating of gasoline. Higher octane levels help prevent engine knocking, which can occur when fuel ignites prematurely in the combustion chamber. This can lead to improved engine performance, efficiency, and longevity. Typically, Octane Boosters contain various chemical compounds, such as toluene or MTBE, that enhance the fuel's ability to resist knocking. They are often used in high-performance vehicles or engines that require premium fuel. However, it's essential to follow the manufacturer's guidelines when using these additives to avoid potential engine damage.
