All I know is... when I used it in my old 944 Turbo (chipped running 1.1bar boost) I could hear the engine ping as I rolled onto boost.

Also... when I used Techron in my old VW GTi and later GTi 16V (Golf II's) I would also get slight ping when I snapped the gas WOT. I just figured Techron must in some way lower the fuel octane. ???

All car had no ping when running only pump gas. Btw I was using Sunoco 94 at that time.
