SeaFoam too much?

[pualrevere]

hey i was wondering if i seafoam every 3000 miles will it cause my O2 sensors to wear out? id rather not pay 200$ for new sensors. what about seafoaming every 10,000 miles?

I would recommend every 10k miles. You really don't need to apply it every 3,000 miles. The intake doesn't (shouldn't) buildup that much carbon in that amount of time to reach 3,000 miles.
