There's no way that the 10% alcohol in E-10 is anhydrous in use. My point is that most problems with fuel (in gasoline or diesel vehicles) end up being moisture related, and that's been the battle for decades.
Our fuel tanks still get air from the atmosphere to replace gasoline volume lost. Yes, modern automotive systems are much better than they used to be, but it's still not a sealed system by any stretch of the imagination.
As for the hyperbole bit, we know how it goes. As I've said before, my carb started to cause problems in my lawnmower, and the thing was almost brand new. The OPE guy, of course, blamed E-10. He didn't have a lot to say when I told him I have run Esso premium E-0 since new, with fuel stabilizer dosing every fill, just in case.
Generally, the water issues are nowhere near what they used to be. In the carb days, E-10 could be a godsend in the winter. Or, depending upon ones environment, E-10 could bring the same vehicle elsewhere to a crashing halt. Similar problems exist today, even if less obvious. A certain oil company up here proudly proclaims E-0 for premium, yet they dose the product with methanol for the winter, which is significantly worse. E-0 or not, one still has to address water issues, particularly in a Canadian winter, and that company has chosen methanol as its solution, despite the fact that it brings a whack of horrible issues all on its own.
As for the gasbuddy quote, I'd agree. There are a couple schools of thought. If a vehicle is going to be stored, fill it good to limit the available volume for water intrusion, or get it as empty as possible so fresh fuel can be added. Both seem feasible to me.
