Lead helped fuel company profits because it was cheaper than the other anti-knock additives, like ethanol.

That's true, and without any legislation or such prohibiting lead they would most likely have continued to use it as anyone who would have phased out lead would have been at a competitive disadvantage. But once it was banned, everybody was again on an even playing field, and as OP explained fuel is a commodity so the higher cost just flowed through to the end user prices, refinery margins stayed about where they were.

In an industry where everyone sells a completely fungible product such cost savings generally are passed on to consumers. Oil companies can profit in the short term due to fluctuations in the price of oil and things like that, but not from something like lead additives, which everyone had been using for decades.

If the end product ends up marginally cheaper, the company will be able to sell more of it, and this will lead to more profit. And sure, when you ignore the cost of the pollution, this certainly benefits the consumer, by allowing them to afford more energy and energy-based products (i.e., just about everything).

But then we come back to ignoring the cost of the pollution. It certainly gets paid for eventually, but by who? Also, it's cheaper for everyone if the pollution is eliminated to begin with rather than being cleaned up later (which is certainly a more energy intensive endeavor).

I think you're missing the point -- the point is that gasoline companies KNEW ABOUT alternative lead-free substitutes for anti-knock (such as ethanol) and chose lead because they perceived it was less profitable. [1] Specifically because ethanol wasn't patentable and TEL was, and ultimately it WAS patented.

It was more that it was patentable unlike ethanol :(
