letters section of the Wall Street Journal
has a letter from
Andrew Randolph, ECR Engines, Welcome, North Carolina
titled
“E15 Gasoline can save you money at the pump”

He claims that E15 has 1.5% less energy than E10 but “should” cost 6 cents per gallon than E10

Since gasoline BTU per gallon varies both regionally and seasonally
and Ethanol depends on the
price of corn,
human labor,
and financial speculation,
(all rising sharply recently)
my gut tells me there is “wiggle room” to make a case either way.
