You can (almost) always run a gas that has a higher octane than
what your engine requires, so if you normally run 87 cargas (something
like 82 avgas rating), then flying somewhere that only has 100LL, you can
burn that without trouble. Aside from the lead fouling and the price,
100LL is a much "better" (cleaner, tigher tolerances, lower vapor
pressure, etc) fuel than cargas, but if your engine can run on cargas, it
can be a good cost saver.

Some airports do have autogas, and it tends to have a slight cost
savings over avgas. Check fuel info at http://www.airnav.com
