I have gone through my 2nd O2 sensor in 6 months. I am running E85 only.

Has anyone else experienced this?

 

are you running really rich?

 

What do your afr's look like?

 

Same O2's after over 2 years of running E85 almost 95% of the time.

 

I ran E85 for an entire year; daily drive through winter and summer, and autox, and never had any issues related to sensors. And during that time, my 02 sensors already had over 100k on them. Hope you figure you the issue.

 

Memphisraynes,
I am a product specialist with Walker Products, a manufacturer and worldwide distributor of oxygen sensors. E85 burns very well and, as posted above, will not contaminate or otherwise harm your O2 sensors. However, E85 is a more aggressive solvent then gasoline, and if your vehicle is not designed or modified specifically for this fuel type, significant damage could occur to your engine gaskets, seals and linings. Complications from this could, in turn, damage your O2 sensors.

 

Four years on E85 and same original O2 sensor. Sounds like your running rich, or exhaust leak at the O2 housing.

 

Probably running pretty rich

 

Yes, I am running rich. 10.75, wot at 25psi..lol.

 

That one an AEM or other gas calibrated wideband? if so then yea, that's even richer than what most consider too rich for E85

(side note, also not doing any good favors for the power output either)

 

That's more rich than my pump gas set up...! Time for a tune man!

 

is the o2 sensor relocated and or rubbing anywhere? theyre known to be very sturdy as the others have stated above, and in my personal experience when i removed my front o2 from my o2 housing i had to weld a 4 foot rod to it in order to crank it off, and i still reused it with no problems

 

no never had this problem been on e85 for 3 years now
