So, my question is is there any reason to rotate to a few tanks of 93 before switching back? And if you say yes, please provide me with a sound, well-reasoned logical reason why - what does it help? What does it do?

BTW - my same response would go to the guy down below who said "don't fuck around and go with flex fuel system" which I disagree with entirely. Don't get me wrong, I have no issues with guys running flex fuel and it is a handy set-up particularly if you live somewhere with little e85 availability (not generally the case here in the midwest). I also happen to think you are as likely, if not more likely, to have an issue running flex fuel and constantly changing back and forth than someone like me who doesn't and only and consistently runs e85 (most of it from the same station).

So far I'm at 4 yrs and 40k miles on e85.
