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.

Paul,

Ed Anderson only burns 100LL and I haven't heard him complain about his O2
sensor.

Since they started putting 10% ethanol in the auto fuel, I've been running
100LL.  My O2 sensor doesn't seem to care.  I'm not sure about the wide-band
O2 yet as mine has been acting strange lately.  I need to determine the
cause for that, could be the 100LL, could be something else.
