An octane booster is a fuel additive that increases the octane rating of the fuel. This, in turn, allows the engine to run more efficiently and produce more power. When the octane rating is increased, the fuel can burn more uniformly, and the engine’s timing can be advanced, which allows for more power and torque production. However, it is important to note that the effectiveness of an octane booster is dependent on the engine’s design, fuel system, and other factors.

High compression engines require higher octane fuels to prevent pre-ignition and knocking. Pre-ignition occurs when the air-fuel mixture in the cylinder ignites before the spark plug fires, which can cause engine damage. Knocking occurs when the air-fuel mixture ignites too early, causing a sharp increase in pressure that can damage engine components. An octane booster can be useful in these engines, as it increases the octane rating of the fuel and can help prevent these issues. However, it is important to choose a high-quality octane booster and follow the manufacturer’s instructions, as using the wrong type or amount of booster can potentially cause engine damage.
