[Mr. Wyndham]

I drove my 2012 ZL1 out on a track the very first time with OE brake fluid...it was fine. There was some fading and a bit of softness to the pedal at the very end of the day...but obviously, I had just gotten it, and was "new to the scene"...so I wasn't driving very hard.

For GM's media events out at a track, they swap out the brake fluid to something with a boiling point in the 530s, as part of the prep process for those cars. For whatever that's worth to you....
