With the correct injectors there is no issue running E85. Also, it *may* void your warranty. I personally use it and have for 30k miles and my dealership hasn't turned me away for anything. I also believe it has been noted to run better in our vehicle's than the recommended fuels. I have almost no ticking like I did on the recommended fuels. (93 from BP and Speedway were considered best near me). I also have more HP compared to those on 93 and a tune. I run E85 and a BNR tune.
