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.

Here are a some sensors life estimates:

Other contaminants such as Silicone (gaskets) and Ethelyne Glycol will
also shorten the sensor life.
I have heard of sensor life as low as a 2-3 hours with AvGas doing dyno
/ tuning with frequent start-stops, running gas and oil rich, where the
sensor does not get a chance to heat up and burn off the deposits.

Cary,

You may be right.  My wide-band sensor seems to have died an early death...
reads "E8".
