I have been playing around a bit with some Ethanol mixtures, but so far, my best results come from mixing E15, with 87 octane, in a 50/50% ratio.
I tried running pure E15, tried running 87 octane + 1 (and also with 2) gal of E85, resulting in E15-E25,
But a 50/50 mix (E10-E12)still gives best performance on my stock ST.
The only thing I haven't tried yet, is an entire tank of 91 octane.
I did try 50/50 of 87 oct + 91 oct, but I found it to be about the same as the 50/50 mix of E15+regular fuel.
I'm sure if the engine load was higher, or a bigger turbo was installed, the difference would be much bigger.
But in stock form, you'd probably hit the sweet spot between an E10 and E12 mixture.
