You should use latex caulk for interior moulding, JK lol.
Isn't leaded fuel not the best for O2 sensors since eventually they'll get coated ?

Yes but the silicone will kill them way faster.

AEM told me that Bosch was releasing new sensors that weren’t affected by leaded fuel. I’m going to look into those when I need to replace these
