    I searched on here for this but didn't find what I was looking for.
    Can I mix say 10-15% E85 with my 93 octane fillup to raise my octane levels as long as I keep a close eye on AFR and trims????? Without having any bad after effects?

    Technically yes, quite a few people have done this. I wouldn't recommend it without some kind of tune ajustment. Your cruise afr would in theory be fine due to the LTFT and STFT, WOT On the other hand would not and it would go lean.
