- Regular (the lowest octane fuel–generally 87)
- Midgrade (the middle range octane fuel–generally 89–90)
- Premium (the highest octane fuel–generally 91–94)
Is higher octane fuel better?
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. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time.
Does premium gas really make a difference?
Raising the octane rating (also known as the anti-knock index) doesn't change the energy content of a gallon of gasoline. A higher octane rating indicates greater resistance to knock, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.
