Most motor fuel today is "enhanced" with ethanol, to a maximum amount of 10% ...legally. Its purpose is to oxygenate the fuel so it burns leaner and cleaner, especially in winter. It does work, it is effective, but mileage suffers a bit. Also cold weather causes a decline in mileage as well.
Not sure of E15 , havent heard of it.
E 85 is 85 % ethanol, the 15% of gasoline (petrol base)is to aid in cold start of the motor.
Ethanol is pretty destructive to fuel system parts.
It can be used to run a high compressio engine though, like 12 -14 to 1 compression, as it is alcohol and it works better with high compression.
Sux...its a matter of intended use.
I wouldnt buy a vehicle that runs on "flex fuel" or E 85 , but i would build a street machine with High CR and run E 85 in a minute. Trouble is , it isnt readily available every where.
Using the correct fuel system components with correct metalurgy is absolutely necessary to keep the fuel system from literally disolving.
