Lol these guys get all worked up when anyone mentions 100LL, meaning it is LOW LEAD.
I got curious about lead content in auto fuel, and I'm not finding it easy to find what standard auto fuel was held to, prior to unleaded fuel days.

TEL remains an ingredient of 100 octane avgas for piston-engine aircraft. The current formulation of 100LL (low lead, blue) aviation gasoline contains 2.12 grams per US gallon (0.56 g/l) of TEL, half the amount of the previous 100/130 (green) octane avgas (at 4.24 grams per gallon),[57] but only slightly less than the 2.2 grams per gallon historically permitted in automotive leaded gasoline...
This
link further indicates that automobile leaded gas was around 2 grams per gallon also. Granted, this is an average, but in conclusion, it sounds like 100LL is about leaded autogas used to be.
