Before this last fillup I was using closer to a 6g E85 10g 93oct mix and was throwing no codes... and LTFT/STFT logs looked good with the exception of some minor timing pulls.

When i get a chance I'll log with this fuel mixture and see how it looks...
I may have to turn down the mixture a bit going forward to prevent the DTC code.
It's hard to say what the blends are, unless you have the flex fuel kit. Even 6 gallons is high for E30. I would start at min. 4.25 to 4.5 gallons of E85 to a full tank and log from there as your baseline.
