Apparently somebody didn't stay at a Holiday Inn Express last night... Ethanol absorbs water. When this happens it creates an awesome environment for a bacteria that excretes acetic acid. Acetic acid corrodes many metals and attacks many of the compounds used to make seals. Some last longer than others in that environment but why would you deliberately run a fuel that requires more energy to produce than you get out of it, can rot your entire fuel system and provides no performance benefit?
We run alcohol in our midgets. The stuff is crazy hard on seals and any exposed aluminum. I have seen an anodized AN fitting that had a tiny (and I mean we couldn't even see it tiny) hole in the anodizing. The alcohol literally ate all the aluminum out from under the anodized surface. When we found it, there was nothing left but a shell of the anodized surface. Craziest thing I ever saw.
no way ethonol runs out . ADM makes that by the shit ton hourly. uncle archie aint losing that cash cow. at headquarters plant they send tanker trucks and rail cars by the hundreds weekly. i imagine there are at least 20 truckloads to chicago every day. and yes i drove that crap for 18 years for adm.
