The worse is, ethanol also has the same effect on gasoline and engines, however since GM needed something they can patent and control and exploit, they invented TEL and pushed it aggressively [0].

This guy is an embodiment of quick-acting karma, and he didn't listen.

If I recall correctly, ethanol needed to be added at around a 10% level to prevent engine knocking. At its peak, lead was present at around 1.1 grams per gallon, so about 0.1%.

Not intended to excuse them. The amount of additive required was why leaded gas was cheaper than using ethanol. And as a reason, three generations grew up with lead poisoning.

Pretty sure there are still people using illegally using this crap in road vehicles I think.

I think you can still buy TEL as an additive in the US for older/smaller engines?

Edit/Answer: No. You get lead substitutes instead [0].
