Avgas and other kinds of leaded fuel will not only destroy the cats. It will damage the O2 sesnors as well as the lead will cause reactions to the platinum covering. This will result in ECU trouble because the complete engine algorithms will be confused.
Using leaded fuel is no good idea.
I am mainly using 98 octan premium fuel (or higher if available) due to the restrictive standard exhaust pipes which are causing a lot of heat and a higher tendency for pinking.
