Well, my  owner's book (VW Vanagon GL Campmobile, 1991, 2.1 waterboxer)
says to avoid  using fuel with alcohol.  When I am where I can get alcohol free
fuel, I  get it, even though I pay more.  Same thing for my Toyota Prius
(the book  doesn't say avoid the alcohol fuel, but I get better gas mileage,
which to me  means the engine is running better).  Besides, I don't like to
pay folks  to commit environmental sin, which growing corn for fuel is.
Sinful in  other ways, too, like driving up food costs.   mcneely

what we are seeing is that it tends to promote rust more in metal tanks and
 also doesn't like sitting very long.    As for using corn to  produce it ,
Va. Tech is studying the use of switchgrass for this.
