Why we stopped, health. Why we started, can’t be anything other than profit.

  Don't forget the part where we tried really hard to stop but denial and corruption meant we kept at it for decades too long.

  Why we started, can’t be anything other than profit. It was a technical issue. The lead prevented valve seat wear. IIRC, Honda was the first manufacturer to use hardened valve seats that didn't need lead. So, ultimately, you can say that it was profit, but then every human activity can be reduced to profit and it no longer means anything.

      How does that article debunk anything? Yes, lead has anti-knock properties. There are other ways around knock, including chemicals that are described in your link. There was no way around accelerated valve seat wear until hardened valve seats became universal, which finally happened because lead was being banned.
