Premium with a lead additive in the Mustang Fastback, but no experience with E85. Do you know what the octane rating is for E85?

Ethanol has less energy content than gasoline. However, E85 also has a much higher octane (ranging from 100 to 105) than gasoline. FFVs are not optimized to E85, so they experience a 5% to 15% drop in fuel economy. This will vary based on temperature and driving conditions. For comparison purposes, aggressive driving habits can result in a 20% loss and low tire pressure can reduce mileage by 6%.

I can’t remember the exact number but I want to say it was like 150 octane. Ethanol compresses much more before it ignites, which is what gives it the bang for the buck in terms of increased octane
