Bob, I'm a chemist, and alcohol in fuel gripes me more than it does you, I suspect. Here is the full story:
The energy budget for generating the alcohol used in fuel, if sourced from corn, consumes as much petroleum as the alcohol replaces. This was predicted ahead of time, amd reported in reputable scientific publications. Despite this, a combination of green politics agricultural lobbying, and actions by congress lead to the alcohol in fuel mandate ... as a replacemenf for MTBE ... to maintain the octane needed for modern engines. So blame Congress, green groups, the africulture lobby, or those who voted in the folks who approved alcohol, but it ain't "the government" which made it happen.
Forgot: the alcohol has a lesser number of BTUs than the petroleum it replaces, so that also engines now consume more fuel per mile. Surely others must have noticed this. My 2005 Dodge pickup lost about 2 or 3 mpg in around town driving. My boat lost a couple hundred rpms at WOT.
There is an old Navy term for this sort of debacle, but we can't use it here.
