Interesting... Leaded gas kills these things... not sure why you "killed" one so quick... maybe it was faulty

A big killer of the sensor can be using silicone that isn’t O2 sensor safe.

IIRC , Permatex says if it’s automotive and their name is on it it’s sensor safe.

If you are buying silicone at a hardware store or similar it’s probably not sensor safe.
