100LL is "high lead"

In the 1940's there was "130" octane avgas, which had REALLY high lead content, and 100LL- "low lead" which had lower lead contant than 130 avegas, but still a lot of lead compared to even leaded autofuel of days gone buy. 80 octane (also virtually gone) was the unleaded avegas.

Interesting, they all had their own colors, 100LL is blue, 130 is green and 80 octane avgas is red.

I miss my flying days...
