Unleaded gas is gasoline that does not contain tetraethyl lead (TEL) additives. Leaded gasoline was created in the 1920s to reduce engine knock and improve fuel octane levels and efficiency, but it was later found to be a pollutant and neurotoxin that damaged emission control equipment and caused serious health problems, especially in children. Unleaded fuel was introduced in the 1970s after leaded fuel was banned in the USA in 1996.
Here are some key points about unleaded gas:
- Unleaded gas is literally gas without any lead in it.
- Unleaded gas is the most commonly used fuel for vehicles and is available in regular unleaded gasoline (RUG) .
- Unleaded gas is the same as regular gas, and since the 1970s, leaded gas has been illegal and is no longer sold at the pump due to health risks associated with neurological disorders.
- Unleaded gas does not compromise vehicle performance when used correctly.
- Unleaded gas produces less pollution and keeps the engine cleaner, making it a great choice for many vehicles.
