No, it's the chemicals in the seafoam that contaminate the O2 sensor. Some argue it's a reaction with the additive package in the gasoline and not seafoams fault. But I am of the thought that gas doesn't kill my O2 sensor in under 500 miles normally so it is the seafoam.
I do similar to what SexPanda says. I wait till I'm going to replace the O2 anyways and seafoam bomb the car. Then after a few tank fulls of plain gasoline. I replace the O2 and spark plugs.
