Re: Fill it with regular or jet fuel?

It won't work with a catalytic converter, as I mentioned. But the cat was not the direct reason it was phased out. The cat was just another part of the Clean Air Act. Pollution and poisoning concerns were the reason.
quote:
Landrigan and his studies played a key role in the government mandate phasing out lead components from gasoline, beginning in 1975, and the federal ban on lead paint in 1978 – culminating in an 88% drop in lead levels in American children by 2005.[10][11]

Except then they would have simply banned leaded gas and, one day, only unleaded would have been available.

But there was a period of a few years where you could buy either. You had to ask, "fill it up, unleaded". And the only reason anyone ever bought unleaded was because their car had a catalytic converter.

That isn't how it works. Just like refrigerants, they phase them out. They don't just stop them. The economy and industry cannot handle cold turkey.

I was alive and buying gas in 1975, so I know what happened.
quote:
1972 — Feb 22 — EPA announces that all gasoline stations will be required to carry “non-leaded” gasoline in the future to protect catalytic converters (which reduce other auto exhausts such as carbon monoxide). EPA asked the Dept. of Health Education and Welfare (HEW) “to provide a health basis for the planned reduction…” But HEW “informed EPA that they could not support the reduciton of lead in gasoline for reasons of adverse health effects since no medical or scientific data were available to indicate that it was a hazard to health.” EPA delays setting standards until 1973, then is sued by Ethyl Corp.

1974 — May 7 – 8 — Hearings before the Panel on Environmental Science and Technology of the Subcommittee on Environmental Pollution of the Committee on Public Works. Sen. Joe Biden (D-Del) calls for “a panel of medical scientists having expertise in the field” to perform a literature review, but concludes: “In my opinion, lead from auto emissions does not constitute a public health hazard.”

Note that unleaded gasoline was banned (to protect catalytic converters) before it was proven that lead in auto emissions was bad.

We'll just have to disagree then. You were alive and buying leaded gasoline, so I can understand your IQ being dropped a bit. I'm just kidding, hope you can take a joke.

I've provided a link with source stating the environmental reasons for phasing it out. Here is more. But we've gotten too far off topic now. You can disgree with me, and I'll leave it at that.
