For those who are flying where only 100LL is available
and you have an oxygen sensor, what do you do? Remove
the sensor and install a plug?

Progress report- I have a planned airworthiness inspection on Tuesday.

Most people don't bother.
As I understand the O2 sensor will recover after
a couple of tanks of no lead.
Some say it still works but the response time
is slowed.
