I came across some information that may be of interest to
the rotary list concerning expected life of O2 sensor using lead fuel. It
seems to correspond fairly closely with my personal
experience.
This reference is basically referring to the
Bosch LSU4 wide band sensor but seems to also correspond with my experience with
the narrow band sensor.
They estimate a 200 hour sensor life using 100LL, I am
getting about 160 hours with the narrow band before it looses useful
sensitivity. But given the expense of the wide band O2 sensor, I
think you guys (Buly?) who are using them can take a bit of comfort that they
are not going to die after 1 -hours of leaded gasoline
use.
