Here's a little anecdote for the books. The person who discovered the 
antiknock properties of tetraethyl lead was one Thomas Midgley. He tried 
thousands of different substances before hitting on this one, almost by 
accident. He was in no way a chemist but a mechanical engineer.

The person who discovered CFCs as refrigerants happen to be one Thomas 
Midgley, yes the same one!

So the same person was able to put in his CV that he had poisoned 
generations with lead and that he overexposed generations with 
ultraviolet light because his CFCs depleted the ozone layer. He came to 
a tragic end by an accidental strangulation before he could find some 
other way of destroying mankind!

Kettering, the inventor of the self-starter, was involved for GM. The reporter or interviewee made one statement that still rings in my ears, "And after all this, we now know that, not only was lead bad for people, it was bad for cars, too. One reason car engines last so long now is..." I don't remember the exact words after that, but the point was lead damaged engines.

I asked her to explain what the mechanism was whereby engines were attacked by it, if it were true. She said it was pretty common knowledge among her colleagues, and described the reactions, the interplay of water and breakdown products, the way chemists talk about things. Louis Hart

Or at least that was my thought about the matter.  Might have had some portion of our fuel supply always renewable.  Or at the very least had avoided the lead debacle.
