The reason for not labling gas is and it has been proven Ky. is a dumping ground for bad gas remember when they put all that ether in our gas 20 years ago and it smelled like poo alot of cars went down because of it. It was eating out gas lines and rubber seals causing some real bad leaks.
Like some one said alchol will eat every rubber seal and gas line it comes in contact with it does not give you more horse power.. I have been a macanic for years and i have been around race cars since i was a little boy here is what you would need to do to get the same performance as gas You would need to raise your compresion 8.75:1 to 10:1 change out your fuel lines change your injectors to alchol compatable ones and raise the cc output of the injector by 20 to 40% change you intake gaskets change your fuel pump change you O2 sensers alchol burns much cooler and slower then gas....
When you use alcohol in your boat engine it will run so lean it will melt the pistons out of it. Oh yah almost forgot you should also change your coils and sparkplugs the ignition in most cars and trucks do not have a hot enough to spark to ignite acohol fuel efficiently. Now we need to reprogram the the computer so we can change the ignition timming got to keep that spark knock to a minumum..
Now i know some one is going to say i have run it in my car/truck before and it didnt hurt anything and all i can say to that is try running about 4 full tanks of e85 and come back here tell us all about it trust me you dont want to do this..
