    For many people who know how to start the engine of a car and drive, gasoline is one important term. As the primary fuel used for engines to run and function, researches have been made to prevent engines getting damaged from the compression, as initiated by the process of combustion. This has lead to the discovery of adding lead to natural gasoline, thus the name leaded petrol. Before lead compounds being added to petrol, it was pure petrol known as unleaded petrol.

    Leaded petrol is basically used for car manufacturers to do innovation with engines, making it more powerful by increasing its compression levels. Using unleaded petrol, on the contrary, typically allow cars to run at the rate at which is originally designed to run.

    One recognizable difference between leaded petrol and unleaded petrol is how they make the cars run. Leaded petrol makes cars runs at a much smoother pace while unleaded petrol do not allow cars to that smoothly as expected.

    Over the years, the use of leaded petrol has become widespread that most people opt to supply their engines with such kind of petrol. But as further studies were conducted, it was discovered that the use of lead petrol can cause significant detrimental effects to the health of humans as well as the environment. Unlike the use of unleaded petrol, where there are lesser health and environmental risks and hazards.

    As this remains to be one industrial problem, the use of lead has gradually been banned. Today, most lead compounds are replaced by additives such as hydrocarbons to sustain the demand of gasoline needed for engines to run. Unleaded petrol, on the other hand, is gradually improved to prevent the use of leaded petrol in various countries of the world.
