Whatever happens with the leaded fuel, just a little makes the inside of the exhaust pipes white.

Not sure on that? Are you letting the sensor fully cycle and "warm up" before starting the engine? I had read that tip somewhere and always try to be sure I do it. I used mine all this past summer and never noticed it getting slow or not reading accurate.
