Aftermarket o2 sensors for e85?

[Andy13186]

Are there any after market o2 sensors that tolerate e85 better than stock? I have completely stock exhaust but e85 has apparently killed an o2 sensor after about 2k miles. Any suggestions? Im conflicted on trying to get it warrantied since it seems like they may try to deny my entire warranty but I have been on the stock tune for a while again now.

Symptoms of my bad o2 sensor was rough idle at times at redlights , also stalled once. got code p0030

Are the F150 5.0's o2 sensors more reliable with flex fuel and can they work on mustangs? I think the f150s can take flex fuel from what I remember.
