- Excuse me for asking a stupid question:
- Does leaded fuel damage the oxygen sensor?
-
- I usually use 98 octan leaded gas :-).
-
- [Absolutely. The sensor uses a platinum catalyst just like a catalytic
- converter. Lead will poison it. Another insidious poison is silicone
- RTV. Even the tiniest bit will plug the pores of the sensor. The
- MFRs caution against using non-compatable RTV anywhere in the engine
