Octane rating

Octane rating measures a fuel’s ability to resist knocking or pinging during combustion in an engine. Higher octane fuels can withstand greater compression before igniting prematurely, which is important for high-performance engines with higher compression ratios. Using the appropriate octane rating ensures efficient engine operation, optimal power, and prevents potential damage caused by knocking. In simple terms, octane rating indicates fuel quality related to combustion stability—more octane means better resistance to knocking under pressure. Different engines require different ratings, so choosing the right octane helps maintain engine health and performance.
