So you’re saying lead was REMOVED from auto gas, or no longer ADDED? ;)

Yeah, I saw the smiley.

But saying it was removed is perfectly legitimate. It was removed from the formulation.
(I hoped I could word that without be obnoxious).

That’s kind of like saying that girls are born with their johnsons removed. ;)

It was developed for aircraft in WWII. One of the reasons US aircraft could run with such high manifold pressures.
They still make it, but only for Reno Unlimited Class racers.

In A&P school almost four decades ago we went over the history of avgas and 115/145 was the highest that was talked about and I can find no reference to a 140/170 grade of avgas.
