It's been mentioned above, but there's generally no real reason to start blending E85 with 91/93 unless you have a car that's been tuned/mapped to take advantage of it and run higher boost because of the effective higher octane. |
Wouldn't 93 be worth it over 91, if you're custom tuned on it? full bolt on, possibly turbo too...93 would have better gains yea?
