Gas grades typically refer to the octane rating, which measures the fuel's resistance to knocking. Higher octane gas is better suited for high-performance vehicles or those with turbocharged engines, as it can prevent engine knocking and improve overall performance. Lower octane gas is more cost-effective and suitable for regular commuter vehicles that do not require higher octane levels.
