Does anyone have any experience with Red Line's SI-1 Fuel Treatment? I'd like to hear what you're findings are. Their webpage claims some pretty impressive numbers.

I bought a bottle to try out, as well as some Water Wetter to reduce running temps in my V12. 120 degrees C cannot be good for anything under the hood. I will post results in the next few months.
