Premium gasoline is a high-octane automotive fuel formulated with an octane rating between 91 and 94. It is engineered to withstand higher compression pressures without premature ignition (engine knock), making it ideal for high-performance, turbocharged, supercharged, and luxury vehicles. The fuel delivers stable combustion, optimized power output, and enhanced engine protection under demanding operating conditions.
