According to an EPA press release:

“Lead has been blended with gasoline, primarily to boost octane levels, since the early 1920’s.

EPA began working to reduce lead emissions soon after its inception, issuing the first reduction standards in 1973, which called for a gradual phase down of lead to one tenth of a gram per gallon by 1986.

The average lead content in gasoline in 1973 was 2-3 grams per 4.56 liters or 1 gallon or about 200,000 tons of lead a year.

In 1975, passenger cars and light trucks were manufactured with a more elaborate emission control system which included a catalytic converter that required lead-free fuel.

In 1995 leaded fuel accounted for only 0.6 percent of total gasoline sales and less than 2,000 tons of lead per year.

Effective January 1, 1996, the Clean Air Act banned the sale of the small amount of leaded fuel that was still available in some parts of North America for use in on-road vehicles.

EPA said fuel containing lead may continue to be sold for off-road uses, including racing cars, farm equipment and marine engines.”

Solved By Shellbourne Fuels.........

In addition to the current process of refining crude oil to arrive at a final fuel:

Shellbourne Fuels synthetically creates additional hydrocarbons through the introduction of catalysts and 100% pure reclaimed solvents from approved medically-certified laboratories.

This creation method is both savory and superior to the existing refining method.
