What issues (precautions) would I see (need to take) running E85 with a flex fuel set-up if I don't drive my car very much sometimes?

For example, it generally sits in the garage from mid-November to mid-March (I start it up every now and then.) For this time period, I would probably just fill the car with 93 octane and change the oil before I put it away, so I'm not too worried there.

However, during the rest of the year, it may go a week or two between drives when I am really busy (I walk to work) and sometimes I can go over a month before I need to visit the gas station. I don't tend to put a ton of miles on the car, so the oil generally gets changed once (toward the end of the summer) during this time period.

Do you guys forsee any issues with running the car on E85 when it may sometimes sit with a 1/4 tank of gas for a week or two? Are there simple solutions to these issues?

Thanks!
