Why unleaded petrol is better than leaded?

Leaded petrol contains lead, a heavy metal that is harmful to human health and the environment. Lead can damage the brain, especially in children, and has been linked to various health problems, including lead poisoning, learning disabilities, decreased intelligence, and behavioural problems. It can also damage the environment by contaminating soil, water, and air.

Unleaded petrol, on the other hand, does not contain lead and is therefore a better choice for human health and the environment. It has been shown to reduce air pollution and improve public health, especially in urban areas. Unleaded petrol also allows for the use of catalytic converters, which convert harmful emissions from vehicles into less harmful substances.

In addition to the health and environmental benefits, unleaded petrol can also improve engine performance and fuel efficiency. Lead can build up in engines and cause damage over time, while unleaded petrol helps keep engines cleaner and running more efficiently.

Overall, unleaded petrol is a better choice than leaded petrol due to its reduced environmental and health impacts, as well as its potential for improved engine performance and fuel efficiency.
