Default leaded gasoline

How much leaded race gasoline does it take to screw up O2 sensors?
One tank full - ten tanks full - or what?

depends on the lead content of the fuel but I cant imagine it taking too long. Never actually tried to ruin a set on purpose.

I believe its not just the o2 sensors that can be damaged but also the cats (if you are still running with cats)

I used to run it in my EvoVIII when boosting over 25psi. C12. Sensors never went bad over about a year of use..... Not sure total gallons but I did run 93 all the time, too....
