You need to find an E0 source, run race gas ($$$) or avgas ($) or distill the crap that comes out of the pump by letting the ethanol and water precipitate out at the bottom and draining off. I actually have a similar apparatus partially built that I intend to use to get as much of the ethanol out of my fuel as possible but it's probably a bit dangerous and to add insult to injury it effectively means I'll pay 15-20% more for gas since I'll end up tossing the ethanol/water away (I'm trying to come up with another use...)

There's a fair body of information on the web about how to do this if you look. Just don't go blowing your house up! Its pretty simple really - just a tank with petcock drain at the bottom, introduce pump gas, circulate water through it and let the ethanol absorb it. After letting it sit for a few days drain the milky white mess out the bottom leaving pure (or purer, anyway) gasoline. YMMV and like I said my setup isn't complete yet but this is what I intend to do for all the engines/fuel lines not designed for the new junk that comes out of the gas pumps.

Unfortunately the resulting gasoline will have too low of an octane rating..... other wise, I would be all over building an ethanol stripper.

Good point - I would not run this in a high compression car.

I suppose you could add xylene/toluene to the resulting mixture and get the RON # up. There are plenty of forced induction tuner guys that tweak fuel blends this way to run higher boost levels... Gets a bit expensive though (neither is especially cheap) and xylene in particular is pretty nasty stuff.

I've been using Stabil in the boat for years (but only at the end of the season). I'm not sure if it has any impact on the ethanol aspect however. For me, 100LL seems to be the optimal solution...well, not optimal :(, I'd prefer non-ethanol 93 octane.

In the 70s I bought 100LL for my Speedster. It had 10.5:1 pistons in it and sounded like you were shaking a barrel of marbles at anything over half throttle on pump gas. After a while the local FBOs caught on and wouldn't sell me gas because I wasn't paying highway taxes and they were (rightly) convinced I was putting the juice in a car of some kind. One guy was a car guy and saw my car and took pity on me for a while, but even he got scared and told me, "no more."

I don't "care" for it, but the 911 does just fine on e-crap-ahol. Now if I had an SC (CIS is vulnerable I hear), I'd be worried...I'm just gonna use it in the boat & other stuff.
