All can be true to some extent but we have e5 for a loong time and I have not seen any totally shot engines or very serious problems at all. It actually works quite ok. Still, I use Alkylate (like stihl premix) in small stuff sitting for a long time and pour some Stabil in stuff that will sit shorter times.
Actually, all modern cracked gasolines will deteriorate, e0 or not, ie it will not be as good in 3-6 months as it was in the pump. That's why you need Stabil more now than 50 yrs ago when most gas was cooked.
Water is always a prmblem so keep your cans shut tight and avoid temp variations and heat. Stabil marine can also help a bit.
Truefuel seems horrendously expensive, and Im from Sweden where e5 95 oct is $2 a liter/quart...
Check for bigger cans of stihl premix/nomix or equivalent and see if the price goes down enough to run for the last tank before storage at least. Another plus is that it is less poisonous to you when running the stuff.
+1 Lars.
Use critical /logical thinking when reading stuff on the internet these days.
