That was a great watch - it’s cool to find out the history.

I must say, society is much better off without widespread use of TEL, but as someone who used to do racecar things, TEL works like magic. A little goes a LONG way, and Midgely did legitimately stumble upon something with very high effect for the concentration (they also touch on ethanol in the video which has the drawback of needing a lot).

I’m not opposed to using it in a small scale racing context (like definitely not NASCAR) because it’s so fucking useful and the quantity is unlikely to cause harm. Unfortunately so much bad has been done with it at this point, I don’t think that’s a very popular opinion.

Whatever your views on it, it’s the only thing that can make gasoline legitimately 120+ octane, and that has huge implications for some types of racing.
