Recently bought an 09 GT500 that's been tuned for E85. The more I've read about E85 it seems like it isn't recommended for the car to sit for long periods of time. I'm trying to figure out what I should do for this upcoming winter. Should I drain the tank of E85 and toss a bit of regular gas in run it through the lines so it'll be okay for winter? Maybe toss some stabilizer in the E85 and just keep that in there? I'm open to options I just want to try and avoid having the injectors cleaned every year and a bunch of junk built up. Any help would be much appreciated.
