I was visiting with Tom @ Parks Automotive & he said Racing Fuel is real hard on O2 Sensors.



He said it messes them up & suggested NOT using Racing Fuel.



What do you guys think?



Thought I'd share this. Jim

I think that's good info. I wouldn't run race fuel then.

I would never run race fuel in a GMMG car. It would actually make the car run worse. It's tuned for 93 octane. Preferably a non ethanol blend.

Matt Murphy told J.D. & I to never run high octane racing fuels. Engines were build & tuned for 93 octane, which was what they had in GA when the cars/engines were built. :)
