When av gas is used with an oxygen sensor, How long before the sensor is junk? Is there a hard and fast rule on time or it depends upon location and usage? What tricks can be used to maybe help shield it from contamination and still be effective?

nobody has any trouble with the lead fouling from av gas or leaded race gas?

Using leaded fuels reduces the sensor’s life expectancy dependent on both the lead concentration and the sensor’s placement. The following table, from Bosch, shows how increasing lead concentrations rapidly kills the sensor.
  1. Lead grams/litre, Sensor Life km
    0.00, 160,000
    0.15, 60,000
    0.40, 30,000
    0.60, 20,000
