in australia at least there are additives in automotive fuel that
degrade on exposure to uv light. this causes a fine flakey sediment to
settle out. this was the cause of 'dont use in aircraft' warnings in
our country.

They *added* stuff to the gas that causes flakey sediment?

Have you got a cite for that?
