All,
Car gas/petrol all Brazil through contains between 20 and 25% alcohol, I believe
it is ethanol.
I have never gotten to speak directly to any Rotax owners about the issue, but
I have had second hand reports and there are a number of positions.
The official Rotax attitude here (and I presume it comes from Kodiak) is that
automotive
fuel is not recommended due to the corrosive effects from the high water
content the alcohol CAN hold. A number of Rotax owners here say it is not
so bad in practice and that the consequenses of lead build-up is in many cases
worse when using avgas- and the difference in cost between the two compensates
for a lot anyway.
Detonation should not be an issue though, as far as I know alcohol has a high
resistance
to knocking...cars that run on pure alcohol here has about 20% higher
compression rate than gas driven ones.
Some people talk of filling drums 3/4 with cargas, topping off with water,
mixing
it all very well for the alcohol and the water to merge and then drain the
water out, leaving gasoline only.....
Embraer have come up with a cropsprayer that flies on alcohol only with a
Lycontissaurus
engine...

Alex, kit 529
