my 99 ta was run with 10%ethanol for a few years before i bought it.......the fuel system was complete junk @ 50 thous miles.....fuel lines and rail were badly damaged,fuel pump-reg assembly was corroded badly.The ethanol eatting and causing the lines and fuel rail to rust jammed all the injectors.......NOW it cost me 3600 to fix it...if it ever does it again i'm gonna try to sue GM ...you would think they would have planned better fuel systems knowing what was coming 
by the way i saved all the old parts just incase this becomes a class action situation.

Ethanol is the tool of the devil, who wears a business
suit and has convinced the guvmint that it will help the
imported oil problem and be good for agribusiness who
makes the feedstock. Never mind that ethanol is a net
energy loss in production. Never mind that it is just a
low grade, semi-pre-burned hydrocarbon. That one
oxygen on there is one you didn't get the energy from.
I expect we will all be seeing it soon.
The VE does not change, though maybe people use
that as a tuning hack. What really changes is the
stoich value, you need slightly less air to burn it
(thanks to that one oxygen and a hydrogen-heavy
molecule relative to regular hydrocarbons). That's
why the smog ***** loved it back in the '80s. On a
regular tune the car will run lean by default.
If you knew the true stoich value of E85 you could
just change that one field in the tuning data and be
roughly right (if you planned on toeing the line and
running that p!ss through your car like a good little
consumer).
Ethanol loves to hold water. But not so well that it won't
let it go, where it will do the most damage.
Methanol in gas, I doubt you'll see. Not until somebody's
third largest campaign contributor figures out how to
make it pay. And it's an even lousier chemical in energy
content, corrosion and poisonous to boot.

not mixed with regular fuel, but used as a fuel source. But motly in motorsports, which is probably why it isnt used on the street. Thats all i can think of, i've seen it used in nitromethanol drag cars all the way down to my one-banger go-kart motor. Never added to gasoline though.

For a while i thought ethanol was why NY and CT gas prices were so much higher than places like central new jersey and even maryland. I figured they'd find a way to make it either cost more or just say it did. But now gas prices are falling in line, i've seen prices on long island as high as 2.70-80 (premium only) while in maryland i have to pay just about 2.65 for premium. New jersey had some of the cheapest gas on the east cost for a while, i would pay 2.40-50 in CT, i could pay 2.00-2.10 in jersey. But now there isnt nearly as much variation so i dont know what to make of my theory.
Does anyone know how ethanol has affected regional gas prices? and how fast is it spreading because it aint in MD yet.
