The ethanol costs about U$1,80 a gallon but we would take in account  20%
to 30% more fuel consumption.
My son tunned up an VW four cylinder 1,8 liter (water cooled)  using a
Schwitzer turbo compressor and is running 2,0 bar  on ethanol. He never

had

pre-detonation problem. ( besides I must tell you, that he sometimes ruins
metal head gaskets, but only when he tries to take off using his car...)
I intend to run my Renesis engine with just a turbo normalizer.

What does aviation gasoline cost in Brazil? 100LL or whatever
they sell down there?

 Castro,
What percentage of  Ethanol do you use over there again?

Aloha George
We are using in regular gasoline a 20% of ethanol.(no lead but the octanage
is higher due to mixed ethanol)
But we also use in some cars the 100% ethanol at about 60% of the price of
regular gasoline.(Higher compression rates engines burning 20 to 30% more
fuel)
The third option are the flex fuel cars that can use gasoline, ethanol or a
mix in any proportion.
