Race gas

[Anduinlight]

OK I know this doesn't matter a whole lot because the racing season is over; but.... I found a good retailer who carries Race gas all year round. it's 110 octane 4% lead (thats bad right?) but the company has many stations that carry it as well as the 97 unleaded
so my question is: is 110 leaded gas alright to run and it not kill my O2 sensor?

Leaded fuel is what kills O2 sensors.

Alright let me rephrase that :p
Is there an O2 sensor i can get that is able to run with leaded gas... or is leaded gas just bad in general?
(i think there was already a post about leaded gas :s )
is there anyother thing that should be done if you are going to run leaded gas???

its not necessarily bad. it just leaves nasty deposits of lead on your valves, turbine, exhaust etc.

If replacing your O2 sensor every year bothers you, dont use it.

Lead is good for everything else though. I say run it when you need it and don't when you don't. Replace the O2 once a year and have fun!

Or just keep a spare o2 to swap in when you feel like running race gas. Then swap back when you refill with 92 oct

I have had good luck with running race gas on my stock 80,000 mile 02 sensor. I would run "race" about every other weekend throughout the last two summers and the o2 sensor is still working good.

A tankful now and again won't kill your o2 sensor too quickly...it took about 2 years to start affecting mine.

Does the 02 sensor do anthing besides be used for logging purposes for us?
