Experience with Using or Ever Heard of 100% Non-Ethanol Fuel?

Ours is called Rec89.  Everything I fill with a can gets it.

I've been running 89, E10 since I bought the truck (5.3 - 6 speed) new 15 months, 24k miles ago.

Averaging about 18.8 mpg over the lifetime according to my 'B' trip odometer, which matches my odometer because it's never been reset.

We have non-ethanol in upstate NY. Sold at Stewart's shops { a local 7/11 type store}. It is 91 octane. I use it in my bassboat, 225 Mercury 2 stroke . As been said, it's good for winter storage, no water/fuel separation. I use  regular in my 5.3 Sierra. I run the non-ethanol premium in my 2016 6.2 Corvette. It runs great in the boat and car.
