I'm in the Mid-Atlantic area that is having our gas cut with 10% ethanol. What, if any, effects will this have on my Camaro? I've been told to expect a slight decrease in economy, but will the fuel system have any issues with it? Many years ago, there was a fuel called "Pepco", which was, (I think), 100% ethanol. Being cleaner than petroleum fuel, there were tons of issues with killing fuel filters as it cleaned up the fuel system, as well as causing butyl rubber fuel lines to collapse.

I did a bunch of reading about this a few weeks ago. All of which may now be garbled in my mind:

10% ethanol is fine, many areas have been cutting gas with it for years.
Ethanol has less stored energy then gas, so expect fuel milage to go down (e85 or whatever is far far worse)

Ethanol absorbes a ton of water. People worry it will corrode things because of the potential water content, however from what I read, you would need to put a hose in your fuel tank to get enough to matter.

High concentrations of ethanol can not be used with standard fuel systems. It requires metal lines, higher pressure fuel injectors, and different ecu mappings. Right now the only cars that can run it with a few exceptions are trucks.

For anyone who lives in NY state, there is not a single gas station that carries e85. The NY Thruway department has a bunch of stations, but they are not public.
