how long will o2 sensor last on 108 oct

[Mike70gtx]

wanted to put some hi octane in to see if I can get rid of the knock. All they had was 108 leaded. Can I run about 10 gallons through it and my 02 sensor survive.
Thanks

Same here, if I'm lucky I can get two tanks before it goes. On the other hand with 100LL av gas it will last about 3 weeks of daily driving.

Mine has been in there for 2 years. I ran 100 av gas and 110 almost all of last summer. I run the 110 at the track now and 93 and alky injection on the street. I also have a heated O2 and that is the reason it has lasted so long. I am glad I changed it over.

a nice trick that works for me is install a new o2 sensor in daily driver w/ 87 pump gas run for 3 tanks of gas , remove & install in the turbo car w/ good gas it seems to last 10 times longer ! happy o2s . shawn

thanks alot guys,
This weekend got a little to busy, so I'm going to give it a shot next weekend. See if I can get it tuned and take it to the track in Shreveport, La. I'm ready to see what it will do and get a time, so I can get ready for the next upgrade.
