Placebo.
I have two changes on my E85 setup. I change my oil at 35%. The last two have been within 5% of the mileage of my last 4 93 changes.
Because E85 setups make so much more power, you may be spending more time in the top/critical 'rev range' (>5000) than you were before. That will affect OLM.
