Yeah, I don't find any performance advantages of 91 octane E0 vs 91 octane E10. 93 octane E10 performs very well in my car.
Fuel mileage is better with E0, but it's also more expensive. I don't know if the fuel mileage improvement is enough to offset the increased expense.
I buy E0, but only for outdoor power equipment due to storage needs. The only clear disadvantage I see with E10 is water absorption over time, which is not an issue with my car since fuel is refreshed at least every two weeks.

|TboneZX3||Columbia also has Hyvee stations with E0, and KC has a few Quiktrips with E0. I guess I'm lucky to have a single E0 91 octane pump in the Cape area.|

The Greater St. Louis Area is E-10 only, no matter what grade, so I always make sure to fill up at Gasper's Travel Plaza (Shell) in Kingdom City when I'm visiting Columbia or Kansas City - E-0 goodness! So I have to drive ~100 miles to get better performance AND mileage.
I'm confident we don't get a choice because no one who cared even a little about performance would ever choose E-10.

Wow, I haven't heard about "Ethyl" since back when unleaded was phased in and we got the small nozzles so only the unleaded ones would fit in the new capped filler tubes.
Assume the cavedog meant non-ethyl as shorthand for ethanol, referring to alcohol content.

But the debate is so entertaining.
Party pooper. ;)
I think there's still enough "YMMV" effect going on for the debate to continue for quite a while, justified or not.

Probably not, but I'll bet you'll notice better throttle response and off-the-line torque.

Guys, I'll fill up with 91-93 "premium" gas today and report my findings within the next 7-12 days. 95% of all my gas has been pumped at Costco, with the other 5% at Chevron. I'll keep today's fill up at Costco. 100% of my previous fill ups have been at the 87 level.
This will settle the debate once and for all.
Day 1 (immediately post-fillup): no change in driving experience felt (ambient temperature 95 degrees)
Day 2: AM drive (appx 40 miles, ambient temp 68 degrees) car felt like there was more power going up 6-8% grades, less stuttering at low speeds, smoother ride.
