Leaded Fuel

[MARINES185]

WHO RUNS LEADED FUEL AND HAS PROBLEMS WITH THEIR
O2 SENSORS. I'M JUST PLANNING ON RUNNING LEAD FUEL
A FEW TIMES HERE AND THERE. WOULD THIS BE A PROBLEM?

leaded fuel is not good for o2 sensors especially regular non heated ones...they won't last past 100 miles usually...if i were you i would spend the 80 bucks and get a heated o2 sensor...i run leaded alot with it and nothing has happened to it...they are supposed to be lead resistant...some guys have ran their same o2 heated sensor for years on leaded fuel and no problems...

My AC Delco has gone through 2 tanks of race gas in between tanks of 94 and works fine. If you dont put in race gas that often like me dont waste your money on a heated O2
