Premium gasoline is generally considered any type of gasoline with an octane level of 91 or greater, with 91 octane and 93 octane being the most common versions of premium gasoline available at gas stations in the United States (93 octane gasoline may be called “ultra” or “super-premium” in some cases).
Is there anything higher than 93 octane?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time. On occasion, this occurrence will likely not harm your vehicle.

Lower-than-expected octane. Low-octane fuel — rated 85 or 86 as opposed to the 87 for regular gasoline — is common in the Rocky Mountain states, said General Motors fuel specialist Bill Studzinski. The practice goes back to the days of carbureted engines, when lower octane helped vehicles run smoothly at altitude.
How can I increase my octane number?
Octane number of fuels can be improved by addition of oxygenates such as ethanol, MTBE (methyl tert-butyl ether), TBF (tertiary butyl formate) and TBA (tertiary butyl alcohol) as well as their blends with gasoline that reduce the cost impact of fuels.
What happens if you put 93 gas instead of 87?
If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.
What happens if you put 93 instead of 91?
“Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.”
