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.

E15 is just what it says and has 15% ethanol or 1/2 again as much ethanol as E10. Corn producers here in the Midwest pushed for 15% for all vehicles but hotrodders, gearheads, some equipment producers, and other car folks made a good case for damage to older vehicles so EPA approved it for newer cars - those built after 2007 or 2009 - can't remember which.
We can still find a few stations here which sell ethanol free gas but they are getting fewer so I buy it to support them whenever I am near one.
Pure-gas.org will show you locations of ethanol free fuel in your state.
