Thomas Midgley Jr.: The man who almost destroyed the planet (twice)

I wonder what people think about the claim that lead was actually introduced to prevent the Pogue carburetor from becoming viable?

If you read about it the consensus apparently was that it didn't actually work, however other articles claim that both Ford and the Breen Motor Company, as well as multiple auto dealers in Winnipeg, tested and publicly demonstrated it achieving 200mpg.

Of course people can claim all these words were wrong or made up, but has anyone in recent years actually tried to make it work?

Whenever I have a brain fart, my 12 year old daughter loudly and sarcastically thanks Thomas. Words can't express how much I appreciate her sense of humor.
