My first (and most likely last) tank of E85
#16
I ran about a tank and a half before switching back. Didn't realize the power difference until I went back to 87 octane. The 2010's seem to get more out of the E85, especially in the torque department.
Just wish Ford could set it up so we could get an extra 10 hp, and 25 lbs of torque with a tank of 91 octane. Word is the 6.2 will jump up in HP and torque with a higher octane fuel. Would be great if you had to do some heavy duty towing.

What is the octane rating of E85 compared to gasoline?
E85 has an octane rating ranging from 100-105, making it a high performance fuel. In comparison, regular unleaded gasoline has an octane rating of 87.

E85 has an octane rating higher than that of regular gasoline's typical rating of 87, or premium gasoline's 91-93. This allows it to be used in higher compression engines which tend to produce more power per unit of displacement than their gasoline counterparts. The Renewable Fuels Foundation states in its Changes in Gasoline IV manual, "There is no requirement to post octane on an E85 dispenser. If a retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect. This number was derived by using ethanol’s blending octane value in gasoline. This is not the proper way to calculate the octane of E85. Ethanol’s true octane value should be used to calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These calculations have been confirmed by actual octane engine tests."
