I think I went over 20K on my last wideband O2 sensor. I have the type you can 're-calibrate'.

You could probably ruin one quicker. You don't want to run one unheated, or one that is improperly placed in the exhaust system.

As long as you can verify the accuracy of the one you are buying, I guess that is O.K. I always like new, so for $90 or less I like the peace of mind that tuning and my resultant AFR on spot on. Its one of the most important tools of tuning, so I make sure to get it right..

Hope that helps..

If you run leaded race gas with the thing, not long at all.

If you keep to unleaded gas they will last you a long time. Mine has been going for about 15k and severl years so far.

I had one that was working fine, but a few trips with
the power off fixed that.

If the thing is always-on (w/ ignition) then you ought
to get pretty decent life.
