Ethanol in the gas ??? Most stations around me are using 10 to 20% Ethanol in their gas now. Its had to find one that does not have it in the gas. WHAT IS THAT DOING, To my ZO6 LS7 motor that I am running. Its in my 32 street rod,so I am not sure what, if anything. I need to do. It seams slower now than it was. Any imput guys. Do I need to get it tuned for todays gas.
shell has no ethanol

Many places having been doing that for awhile. I believe all stations in MI have 10% Ethanol, and it has been that way for as long as I remember. It replaces some other additive in the gas and it supposed to burn cleaner that way. My friend from New York says that he gets 2-3 mpg better in his 01 Saturn on the gas there that does not have the 10% ethanol compared to the stuff he gets while at school here in MI with it.
in FL all gas has it now.
What it is doing is robbing HP, decreasing your mileage, and you can NOT let ethanol sit in tank for more than 3 months, ethanol absorbs water so if you live in a climate with lots of temperature changes, its less than 3 months.
Alcohol is also a solvent, if you have any kind of rust or crud in your tank (or the tank at the gas station you got it from) it will dissolve it, and get pumped through the system.
Because of its corrosive nature, boaters have noticed it eating through fuel tanks, lines, and gaskets in higher concentrations.
The other problem is it is added to the fuel at the time that the gas stations tanks are filled, making that 10% VERY inconsistent. People have randomly tested stations and found ethanol concentrations varying from 6% to 90%.
I could go on, but bottom line E10 is the debbil and has no benefits what soever.

I think it has caused somewhat of an erratic idle with my supercharged speed density tune. Took it to my tuner after I nothiced it, he blamed it on ethanol. Generally in the winter months the concentration can be higher. I'm not sure why though.

I saw a show on tlc that was talking about possible fuel sources for the future and it said ethanol is great for power and would kick *** in dragsters but they did say it burns really fast so less mpg.

Ethanol KILLS your mileage, and as said above is very inconsistent, chevron does not run ethanol around here, Shells here are huge on ethanol, some days my cars runs like a bat out of hell and other days not worth a crap so lately ive been staying away from ethanol fuels.
I thought methanol was corrosive, not ethanol? Ethanol is great stuff...in cars that are built for it, but we really need to move away from all this corn based ethanol. In texas I usually see 10-15% ethanol, I think I would be suing if I found out my tank ended up with 90% ethanol (if I even made it home on that tank).
