Race fuel

[spray]

Will it hurt your o2 sensors if you were to put like 5 gallons of race fuel 112 or116 on top of a 1\4 tank when at the track spraying?

Eventually leaded fuel will take it's toll on O2 sensors.

Thats kinda what I was thinking too. Does anyone know how long the o2s will last using race fuel about once a mounth

I have gone about 10K miles using leaded fuel occasionally with no problem. But, I know people that have ruined their sensors on the first tank.........you might try to find some 100 unleaded..

Killed mine within a week but didn't throw any codes, The 02s just did not read right so it caused all kinds of diagnostic problems. Are you not worried it will lean you out to much since your spraying????
