Rest In Peace, old friend, your work is finished..... 
If you want ON or OFF the DIESEL 'KnOcK' LIST just FReepmail me..... This is a fairly HIGH VOLUME ping list on some days.....

I don’t see it discussing the only thing that really matters, cost.
If it is starting with ethanol, which is already more cost per mile than gasoline, then it is a worse solution than ethanol. It has the cost of ethanol, and then additional processing cost.
Farmers are used to smelly things but women are a harder sell. Butanol is the sickly smell of a Sharpie marker.
Butanol, the gasoline substitute promoted by billionaire Richard Branson, is headed for its debut at U.S. pumps as soon as next year in a challenge to ethanol’s domination of the $26 billion renewable fuels market.
Like ethanol, the colorless alcohol can be brewed from corn, though it packs more energy when mixed into gasoline. Butamax Advanced Biofuel LLC, funded by DuPont Co. and BP Plc, is retrofitting an ethanol plant in Minnesota to begin making butanol in commercial volumes in 2015. Gevo Inc., backed by French oil producer Total SA and Branson through his Virgin Green Fund, already runs a distillery 60 miles away. Both say they’ve lined up clients for large-scale deliveries.
Maybe.
Unlike ethanol, butanol is less corrosive, doesn’t attract moisture which can cause harmful “phase separation” of the fuel, and can be mixed in ahead of time and shipped through existing pipelines. It has a higher energy value (110,000 Btu per gallon versus ethanol’s 84,000 Btu), and is safer because its flammability is similar to diesel fuel. So why aren’t America’s boaters, motorists and gas-powered tool and toy owners using butanol?
“Part of the answer is how the stuff is - or was - made,” wrote BoatUS Seaworthy Magazine Editor and Damage Avoidance Expert Bob Adriance. He says, “Back in the 1980’s when the government was looking at biofuels, the cost to produce butanol was much higher than ethanol. Congress also gave ethanol a head start 30 years ago with a subsidy to produce it from corn. However, the subsidy is now expired and new technologies have made the costs to produce both fuels similar, although butanol is ultimately far less expensive to produce in terms of the amount of energy delivered per gallon.”
Interesting.
One more carbon ... Kinda like the difference between heptane and octane.
END SUBSIDIES and MANDATES now!
I wish I could send a BILL (as in Invoice) to the folks in Iowa for all of my incurred expense (Repairs, Replacement costs, loss of Mileage, Downtime etc etc etc) for their beloved Ethanol subsidies aka Frankin Fuel.
Butane is a bastard gas.
