Today, 100 octane low lead ("100LL") aviation gasoline (or "avgas") contains 50 percent less lead than it did when the lead NAAQS were first introduced, dramatically reducing lead emissions from general aviation. May also contain several additives at <0.1% v/v each. Definition Aviation Gasoline Description AVGAS is the most commonly used fuel for piston engines. Avgas is primarily used in piston general aviation aircraft. Due to the lead content (even in 100LL form), a bromine compound is added to the mixture to scavenge lead residue from the engine. Continuous revision for greater safety I have used it straight and it runs brilliantly but also found that runing it with 1/4 to 1/3 100LL worked well. Medical research since then has shown that much smaller lead levels can cause serious health effects, especially in children.
