Granted I got the flex fuel conersion for mine, along with the tune for it. But it's true what they say about the not loving the cold weather and start ups. Nothing that letting it warm up before taking off can't fix. Which I do anyway, but I know not everyone does.
I usually only put in the E85 when I know I'll be doing a bit more 'spirited' driving, since this is my daily, and Jay's isn't super convienent with where I live. Not too mention i don't really want to run straight ethanol all the time with my fuel lines, since I would really like my car to last a while.
