    How many of you are running E85 as daily? What mixture is in your tank? How long have you been running it?

    I'm running it daily at 50% and it has been 3 months already.

    Most N54 around here, including me when i had mine ran e40. I tried to run more with the BMS flash but my LPFP died pretty quickly. No issues around here on e40. That's at least 12 months of e85 use too.

    E50 for a month or so until the first pump died, now E30 for the past 6 months. Once the FFTEC pump shows up then back to E50.

    Nope, I stop running E85 (run it straight) after Sept. Once it gets sub 50s, I started having problems with cold starts. Also, because I was tuned on summer blend E85, the tune tends to be overly aggressive for winter formula E85 (which is closer to 70% ethanol).


    Even during the summer, it's inconvenient to strictly gas up on E85 and it's a real pain in the ass to switch from the E85 to Pump Map. Really don't like to run it bone dry, so usually it takes 1-2 tanks of 93 after a tank of straight E85 to get the fuel trims back where they should be.

    I run 30-35%. 40 is borderline fuel codes but my car seems to love it!
