leaded gas will significantly shorten the life of the wideband sensors, unfortunately it varies greatly, so its hard to say how long it would last, its also heavily dependent on the tune/setup

I'm surprised that you had a problem with race gas.Even leaded race fuel nowadays has almost no lead.

It just shortens the life of the sensor... Refer to the AEM UEGO instuctions manual since it states the mileage expectancy on leaded gas. It's about half the lifespan, but we are still talking about over 10000 miles at least, and not several days. As stated earlier, it also depends on how rich the AFR is, and does the sensor have a chance to self clean, or was it subjected to constant WOT fulls with rich A/F's...
