My C150M POH shows an approved fuel grade includes AVGAS 80.

Assuming you could find 80, how safe is it to run?

And, what are the modifications made to the fuel system to run MOGAS?

On a purely theoretical level, what would be the ramifications of fueling
up an unmodified Cessna 150 with 92 octane MOGAS?

Depending on where you live MOGAS may not be approved. Only certain
blends of MOGAS are approved by the FAA and many communities restrict
those blends. .
When I had the Aeronica I found the engine ran much cleaner on 80. It
burns a bit hotter so you get less deposits. The only reason 80 isn't
the preferred gas around the world is because higher compression
engines need the 100.
