I have been using it since late '06. I revisited that thread to laugh @ stockcarboy saying it’s petroleum. e85 cleaned the SHIT out of my fuel system, I ran it through the stock injectors for a few weeks and they looked super clean after. I also took out the iridium plugs I installed in '05 at the same time and the carbon was coming off…
If I’m getting low on fuel and I am not close to an e85 station, I’ll just toss in some 87 octane (no need for 93 when you are blending 105+ octane fuel in) and take a few spirited turns to aid in mixing. It just runs a bit rich, but since I still have my STFT/LTFT’s enabled it runs just fine. I change the oil pretty regularly, so I don’t worry too much about it.
Anyhow, I lol’d pretty hard at some of the negative comments about e85 in that thread.
