I would think the only time to use alcohol would be if avgas was no
longer available. At least then the higher compression engines that
can't run on premium auto fuel could still operate. But after all the
engine changes were made that are needed. And put up with the shorter
range with the same fuel tank capacity.


What is the compression ratio for on of the Indy cars? They have been running alcohol for years. It is more an ignition
timing and material issue...
