Can Some Leaded Race Fuel Hurt Cats?

  1. I want to bracket race my 2014 GT abit. Does anyone know if mixing a 50/50 mix of reg. gas and 112 leaded race fuel would hurt anything if used occasionally. I'd appreciate answers from those who truly have some actual knowledge about this not guesses. I ask as I have 2 drums of race fuel to use. Once off the track I would only use reg. gas again. Thanks in advance!
  2. not sure of the effects on the cats, but leaded fuel will almost instantly kill your costly O2 sensors
  3. You gain nothing from running race fuel in a motor that is not tuned for it. Yes... it will kill cats too. Maybe @Jinx can use it? :shrug:
