Just like the title reads or will it create a problem with the O2 sensor?

It will shorten the life of the o2's and cats (if it has them) but I know plenty guys with late models doing it because of their use of nitrous or boost.:yes:

regular use of leaded fuel will kill off what D-man said..... but occasional use will be harmless....prolonged use will kill the cat and o2....
