Ethanol or No Ethanol?

Ethanol or No Ethanol?
Just curious what your thoughts are on gas for my 997.2?
I've been using BP's 93 Octane that contains 10% Ethanol... then the other day I stopped at a convenient store private gas station, they had 93 octane that was "ethanol free".
Seems to me like the car is running a little sluggish with the ethanol free gas... I noticed this before I put the 19" wheels, but had been meaning to ask this question.
Do you guys have a preference for fuel regarding ethanol?

Do not use any fuels containing more than 10 percent

We recommend, however, to change to a different
fuel or station if any of the following problems occur
with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially
at high altitude or at high temperature.
– Engine malfunction or stalling.ethanol by volume.

I was thinking ethanol free gas would be better? Seriously, I haven't a clue... this private station just started offering ethanol free gas about 3 weeks ago, so I stopped to buy some milk on the way home, saw they had 93 etoh free, so I topped off my already 1/2 empty tank... next day, the car felt a little sluggish (this was before the new 19" wheels)...
Bad gas?
Maybe its just my imagination... now that I have the new wheels on, when I get empty, I'll try a full tank of 93 etoh free...

ummmmm he said his car was running worse with the ethanol free gas... worse isint coming lol .... e15 isint gonna be an issue... just bypass it and go e85!!! if e85 makes awesome power when tuned for it... and we all run e10 why would e15 be so bad?

You can tune your car and run E85 with it. Running is not the issue. Go ahead, try it and report back after a year's usage.

The Gtech showed bigger RWHP power and the Durametric allowed me to watch timing curves(more timing=more power)...also with the fact that Durametric has a time scale on it....I could crunch the numbers in any RPM range to determine which combination would get the best time!
And the gas with Ethanol always did better....
NO kidding,

Amazing what's going on here. Ethanol boosts power but that is not the issue. This is a Porsche forum and Porsches are not ready to run more than E10 and even that is iffy, if you care for reliability and fuel efficiency. There is no ethanol-laced gas in Europe - they lack a corn lobby over there. Feel free to drink the performance or eco Kool-Aid.

I have Gt3's running E85 straight for over 10k miles right now with no issues.. E15 isnt going to do one thing for reliability.. if anything will last longer with cleaner valves, Pistons etc.. As far economy it drops a tiny bit on 15% but well worth the gains IMO..
