You could also say that water and ethanol (alcohol) are miscible...
i.e., they will blend into a homologous mixture in any ratio and they
will not separate without outside intervention.
The physics of this subject are interesting as well. Having said that,
we all must still practice good "fuel hygiene" (checking sumps, making
sure the fuel we use meets quality standards, etc.) in order to keep
that thing in the front of the airplane spinning they way it is supposed
to.
You can be careless in a car; it is already on the ground anyway... not
so with anything that flies.
JMHO.

Mark L, I just read your page on your crankshaft odyssey. Are you, and
any others using Corvair engines, still satisfied that a new billet
crankshaft with good fillet radii (along with the 5th bearing and prop
indexing) will eliminate the issue of broken crankshafts in Corvair
aviation engines?
This also got me thinking about a YouTube video about
engine efficiency that I watched a few days ago. Last September, Larry
F, started a thread that included the topic of ethanol. I added some
info about the benefits of ethanol and included links for those
interested in the science. On other lists I hear a common
misconception that ethanol is "hydroscopic." That is not a word and
they usually mean hygroscopic. However, that is not factual, either.
Ethanol is hydrophilic. Anywho, a few days ago I watched an
interesting video on the topic as it applies to engines that many of
you may enjoy. Here it is: https://www.youtube.com/watch?v=6_DQPLihXfo
