This is one of the old myths.  Current reports done by valid research
centers show a 15 to 25 percent change with injected systems are the maximum
variance.  And that is using E85.  Vehicle mfr state that this is currently
the maximum alcohol because of the additives used take up the other 15
percent of the fuel.  (several stated that an engine would have to be
designed alcohol only to be used for pure alcohol) All are agreed that there
are a lot of variables in the mpg figures due to engine designs currently
trying to multi (flex) fuel.  Some of the techniques used to make the cars
flex fueled are kind of interesting.  Fuel tanks, hoses, fittings, gaskets,
seals, and other small parts changed.  This could lead to a future
maintenance nightmare of getting the right parts.

Several mfr are currently doing work with E17 to E22 fuels, including a
state funded project I found in California that seems to have a Canadian
origin that goes back to the VW study that I still havent found.  However
from the dates I am positive is the 1995 to 1997 work done for the brazilian
gvt.
