Probably from tetraethyl lead, which wasn’t banned in common fuels until the 70’s in the US. That said, there are enough other sources of lead (e.g. old paint)

Probably from tetraethyl lead, which wasn’t banned in common fuels until the 70’s in the US.
That said, there are enough other sources of lead (e.g. old paint) that this isn’t guaranteed to be right.
- reaperducer 7y agoProbably from tetraethyl lead, which wasn’t banned in common fuels until the 70’s in the US. Except in California, which had leaded fuel well into the 90's for rich people's collector cars. Another example of the do-as-I-say-not-as-I-do sorts of things that happen in California.
- undersuit 7y agoYep, California banned leaded fuel for automotives in 1992, 4 years before the United States federal government followed up. https://archive.epa.gov/epa/aboutepa/epa-takes-final-step-phaseout-leaded-gasoline.html https://archive.epa.gov/epa/aboutepa/epa-takes-final-step-ph...
