indicates greater resistance to knock
, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.
Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.

Other things to consider: failing to use high-octane fuel in your premium vehicle could
cause engine knock or pinging
, which sounds like there's a large woodpecker under your hood; you could experience damage to your components; and using the wrong octant level could even void your warranty.
