- Reason077 6y ago100 = 100 octane, a common octane rating for avgas (aviation gasoline) UL = unleaded.
- sokoloff 6y agoAlso worth noting that while the lean octane rating of avgas is 100 (as compared to auto fuel’s lean rating of around 85), the rich octane rating of avgas is around 130, providing increased margin against detonation on high-power takeoffs. It’s a mistake to think “I can buy gas labeled as 93 octane at my local Shell station; surely they can find a way to find just 7 more points or detune the engine slightly.”
