The major Mogas concern I have is that so few have endorsed the
concept, that it may not ever get to critical mass. The engine
manufacturers ignore it or don't support it, the AOPA never mentions
it, many FBOs simply state "our insurance won't cover it", the hodge
podge of state gasahol laws are eroding the practicality of it all, and
lastly we owners of low compression engines simply are not using it
anywhere near as much as we should.

Mogas is simply assumed by most "real pilots" and mechanics to be a
substitute fuel, inferior or harmful to engines, and something that is
only used by a small minority of old aircraft owners. For those and
probably still other reasons, mogas isn't widely available for cross
country use. The advantages of Mogas are only talked about in forums
such as these.

Mogas users have to get this situation changed. Some day 100LL is
going to disappear by an EPA mandate & then where will we be? I feel
the 100LL users are whistling in the dark as no substitutes seem to be
forthcoming to their leaded fuel.

Both Aviation Consumer and AOPA pilot have articles on this subject in
their current issues. They both conclude that 100LL is really not
going to be going away in the foreseeable future (the EPA has delegated
the issue the FAA and the FAA is not interested in getting rid of
100LL), and they also both describe research into alternatives that is
in fact going on now.

One statistic that interested me was that 70% of the GA fleet does not
have the high compression engines that need high octane/leaded fuel.
However, the 30% that does burns 70% of the gas.
