contained approximately 4.0 grams of lead per gallon; average lead content was reduced to 0.5 gram/gallon in 1985, and
still further to 0.1 gram/gallon in 1986.
"Unleaded gasoline" is allowed to contain no more than 5/100ths of a gram of lead per gallon.
Why remove lead from gasoline?
Lead is extremely toxic. Studies show that exposure to high concentrations of lead, particularly in young children, can result
in damage to the central nervous system, and may be associated with high blood pressure in adults. Human exposure to lead
typically occurs via inhalation of air and ingestion of lead in food, soil, water or dust.
Cars and trucks produce air pollution throughout their life, including pollution emitted during vehicle operation, refueling, manufacturing, and disposal. Additional emissions are associated with the refining and distribution of vehicle fuel.
Air pollution from cars and trucks is split into primary and secondary pollution. Primary pollution is emitted directly into the atmosphere; secondary pollution results from chemical reactions between pollutants in the atmosphere. The following are the major pollutants from motor vehicles:
In the United States and the rest of the industrialized world, gasoline is definitely a vital fluid. It is as vital to the economy as blood is to a person. Without gasoline (and diesel fuel), the world as we know it would grind to a halt. The U.S. alone consumes something like 130 billion gallons (almost 500 billion liters) of gasoline per year!
Diesel is better for the environment
Cars emit greenhouse gasses, such as carbon dioxide, which contribute to global warming
Some air pollutants and particulate matter from cars can be deposited on soil and surface waters where they enter the food chain; these substances can affect the reproductive, respiratory, immune and neurological systems of animals.
Nitrogen oxides and sulfur oxides are major contributors to acid rain, which changes the pH of waterways and soils and can harm the organisms that rely on these resources.

Hydrogen (H2) is being explored as a fuel for passenger vehicles. It can be used in fuel cells to power electric motors or burned in internal combustion engines (ICEs).
It is an environmentally friendly fuel that has the potential to dramatically reduce our dependence on imported oil, but several significant challenges must be overcome before it can be widely used.
Liquefied Petroleum Gas (LPG): Most cars powered by LPG in the UK are hybrid vehicles and are much more environmentally friendly and fuel efficient than petrol engines. They produce fewer emissions of carbon dioxide, hydrocarbons, carbon monoxide and nitrous oxides than both petrol and diesel powered vehicles. LPG also causes less wear and tear to the vehicle and is more fuel efficient, saving you money.
