Default leaded 110

will leaded 110 kill the dynotune wideband o2 from innovative motorsports? I have my car running and it has been 12.2:1 WOT for about a month I put some 110 in the car and it dropped to about 10.1:1 WOT then I tryed changing one 02 and it then read around 11.1:1 WOT. What else could have happened? Thanks,
Joe

P.S. All passes on motor

Over time lead will damage O2 sensors.
Increasing octane will also change your EGTs, so depending on where the O2 is mounted, the change in temp can change readings a little as well.

WBO2s can generally clean themselves with a few heat cycles, but can get contaminated with lead over time. I've killed a few narrowbands with race gas, but not a wideband so far.
I would recalibrate it and give it another chance.

I run a lot of leaded fuel and use DENSO O2's with good results. My last set lasted me around 8000 miles.
