Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates.

Premium gas has a higher resistance to engine knock in luxury and performance vehicles with turbochargers or high-compression engines, so you can hit that horsepower smoothly. Additionally, premium gas can increase fuel efficiency, potentially bringing better gas mileage for longer while decreasing emissions.
