I basically overpaid around 25 cents in fuel energy content for the E85 but got a whole ~92 octane tank for over a dollar less than a full tank of 91. Good tradeoff.
It's too bad the E85 station I fill at has very expensive gas prices, otherwise I could do 20% E85 + 80% 87 blends conveniently and at lower cost for the E85. |
Those are interesting experiements but speaking for myself I think I'd last about 2 tankfuls before saying "too much hassle!" and just filling up at a single location. (Although it might be a fun way to amp up a tank for the STi, hmmm....)
