E15 gas...
About 10-15 years ago, it was all the rage because of concerns about oil shortages. Ethanol use would help us beat offshore oil dependence (now kind of BS). Predictions of a massive corn-to-ethanol move and economic benefits here in the Midwest never really materialized because of very high costs to transport it by truck and lack of pipelines. There were reported benefits to air pollution, particularly CO2, but these have been more recently more nebulous due to increased ground level ozone reports from Brazil where ethanol is much more widely used.
I guess my bottom line on the whole thing is that it's really another farm subsidy and corn production seems to be the most highly subsidized large crop in the USA. Like all government subsidies, this one is very well established and will be very difficult to eliminate. Face it E10 is probably here to stay. I don't want to see E15 implemented and have written my senators and congressman to fight this move.
Ethanol, like unleaded gasoline, is different from the blends common prior to it, but neither will destroy your engine. That, rather than some great inside conspiracy is why you don't see warnings on every bike, car, truck and piece of equipment with a gasoline engine.
