Yep, I fill up every other day in my TL, so the fuel doesn't sit in it long at all. I just like the more miles per tank with pure gas in it. With everything else though I use pure and a stabilizer.
I have "heard" as soon as two weeks on the breakdown of Ethanol depending on climate. But 30 days for sure.
