The main differences between research octane rating (RON) and motor octane rating (MOR) are the particulars of the operating conditions. The fuel is more stable the higher the octane number. According to octane rating, retail gas stations in the United States offer three different classes of gasoline:
- Premium (the highest octane fuelgenerally 9194)
- Regular (the lowest octane fuelgenerally 87)
- Midgrade (the middle range octane fuelgenerally 8990)
