 Hi Paul,
     The EAA Hotline mentioned that California is going to go all
 ethanol blend on ARCO Fuels
 soon.  Oddly enough, I don't recall ever hearing whether there
are
 any pros & cons about ethanol
 and our rotaries.  -  What's the scoop?
 Thanks,
 Robin

I think there are some issues with fuel tanks and plumbing.
As I recall it is not recommended for composite fuel tanks.
Despite being several cents cheaper per gallon (probably due
to a CA state tax break) it does not dominate sales in CA.

I think the main problem with alcohol in gasoline is how to keep it
from adsorbing water from the air Think water in the fueling
system).

I'm not sure water in the fuel is as much of a problem as people
think.  If it is absorbed in the
alcohol it will pass through the system and be used just like an ADI
(anti-detonation system) with
the Reno Racers or when we Minnesotans add HEAT  (alcohol product to
absorb moisture) to our gas
tanks to prevent gas line freeze.  Also, there is an aviation fuel
called AGE85 (Aviation Grade
Ethonal) which is 85% ethonal being used with little or no problems.
Water injection has been
used over the years in various aircraft engines.  Paul is correct
about the fuel system
incompatability issue.  Hoses, o-rings and bladders may have to be
changed to stand up to the
alcohol.

Water injection, if I am not wrong, doesn't make water circulate
through the fuel system. My concern is the presence of water in the
fueling system, any place, and the corrosion, oxidation, freezing &/or
displacement of combustible it could produce anywhere, anytime.

Corrections are welcomed. We are learning everyday,
