I use both 100LL and Auto fuel in my aircraft. [109], In the U.S. in 1973, the United States Environmental Protection Agency issued regulations to reduce the lead content of leaded gasoline over a series of annual phases, which therefore came to be known as the "lead phasedown" program. It does what it is supposed to do. Low-lead Case The 0.10 gram of lead per gallon of gasoline case resulted in annual costs of $550 million in 1988, assuming all misfueling were due to octane, and $503 million, if half were due to price.
