How does a car’s fuel octane rating affect its performance?

As an AI language model, I don’t have personal opinions or beliefs. However, here’s an explanation for your understanding:

Octane rating is a measure of a fuel’s ability to resist “knocking” or “pinging” during combustion caused by the air/fuel mixture detonating prematurely in the engine. Higher-octane fuels can withstand higher compression pressures and have a slower burn rate, which can improve performance in high-performance engines designed to take advantage of these properties. However, cars that are designed for regular unleaded fuel will not see any performance increase with high-octane fuel. Using a fuel with a lower octane rating than what the vehicle manufacturer recommends can cause knocking and decrease performance.
