Setting all the MPG and HP..etc aside, the biggest issue with Ethanol fuels is moisture. They attract moisture/water and will go bad quickly. This is why you should never use any ethanol fuel in a lawn mower/race car..etc. anything that sits for extended periods of time. And if you simple must, then add some sort of stabilizer.
In fact, the last lawn mower I purchased, specifically said to use "clean" 100% fuel, any ethanol fuel will void the warranty.1991 325i MT2 Touring (JDM bro)

Just old Cars are not meant to run corn.
Race Cars cause they truly car about mpg, correct. If they did then they'd be working to go the whole race on one stop. E85 has great resistance to detonation as does Alcohol.
FI cars burn it like a champ but it does not give you better mpg.

Originally posted by RedTeam View PostI agree with Wschnitz. Ethanol is like a middle ground between gasoline and top fuel. Lower energy density, but also a lower air to fuel ratio. Yes, it will corrode an engine quickly if it's not designed for it, but as long as it's fuel injected with O2 sensors, it should have no problem burning it.Last edited by M-technik-3; 05-10-2016, 06:24 AM.

I actually have a CFN account, and it's surprising how many commercial fuel station carry E0 fuels.
We load up the race cars and some of the other cars with it when ever we get the chance. My buddy refuses to run anything but E0 in his 1M (can't say I blame him..)1991 325i MT2 Touring (JDM bro)

I'm honestly afraid to go e85 on the s4 because of the inconsistent tendencies.
There's a station about a half hour away that carries it, but I don't feel like testing and worrying about it going bad in the tank while the car sits?
Now as far as fuel systems go, the S4 is good for it, I'm even running the walbro 450 e85 pump already.
All this talk kind of makes me want to go for it. I will end up throwing a rod eventually (will be around 550awhp/tq), but hey it's not my DD anymore.No E30 ClubOriginally posted by MrBurgundyAnyways, mustangs are gay and mini vans are faster than your car, you just have to deal with that.

E85 is a godsend to turbocharged engines especially here where 91 is all we get which is not adequate on a stock turbocharged vehicle
I tried my 335i with a 91 octane tune and it lasted about 20 mins till I went and found an e85 station1989 BMW 325is Lachsilber metallic 5 speed

My friend was a chainsaw mechanic for Stihl, he said that most issues with them not running was ethanol in the fuel, it kills the carb seals, float bowls, fuel lines. The fuel systems in anything not made in the last few years isn't made for it.-Christian

The primary reason your fuel mileage goes down based on the amount of Ethanol in the fuel is the Stoichiometric Air/fuel ratio for Gasoline is 14.7:1 (This is based on weight not volume) and Alcohol is 6.4:1. Gasoline weighs between 5.8-6.5 pounds/gal and Ethanol is 6.5 lbs/gal so there is not a huge difference in weight/volume but there is the issue of almost 2.3 times the amount of Alcohol by volume to achieve the correct AFR. Adding 10% Ethanol to your fuel should under the best of conditions at the same time cost you 10% more total volume to meet the AFR you are looking for.
Then there is the hygroscopic properties of Alcohol (it absorbs water from the air) and the corrosion (hoses, fittings, gaskets etc) that were not designed to live in a Alcohol environment.
