Compounds of the element Lead (Pb) was added to gasoline to help prevent pre-ignition, commonly known as "pinking" or "knocking".
Environmental concerns required the introduction of non-leaded gasolines, which we have now. Modern cars use computer controlled spark timing and fuel injection timing to prevent pre-ignition.

Why glycol is added in aviation gasoline?
it is added to prevent freezing of gasoline
Can unleaded gasoline be used in an engine made for regular gasoline?
Unleaded gasoline is regular gasoline. Lead used to be added to gasoline to prevent engine knocking but the practice has been banned in most developed countries. 2nd Answer: There are some engines, a lot of them not in cars, that are made to use regular gasoline. They are designed so that the lead in regular old gasoline will build up on certain moving parts, and keep them sealed against engine pressures. Unleaded gas is not good for this type of engine, at all.
Do they add smell to gasoline for safety reasons?
Yes, a smell is added to gasoline for safety reasons to help detect leaks and prevent accidents.
Which compound is added to petrol to prevent engines from knocking?
Antiknock additives like tetraethyllead (TEL) or methylcyclopentadienyl manganese tricarbonyl (MMT) are added to petrol to prevent engine knocking. These compounds increase the octane rating of petrol, reducing the likelihood of premature ignition in the engine.
What element is added to toothplaste to help prevent tooth decay?
Fluoride
Why was lead added to gasoline and why is lead not added now?
lead is a cheap way to raise the octane rating of gasoline, thus preventing knocking in high compression engineslead destroys the catalyst used in exhaust system catalytic converters, requiring expensive repairs to meet smog rules again
What was the purpose of adding lead to gasoline?
Lead was added to gasoline to inexpensively increase octane ratings and to also help reduce engine knocking.Increasing octane and reduce engine knocking are exactly the same thing, as the test method to measure octane of a fuel is to see when a standard engine begins knocking. The higher compression ratio the standard test engine can be operated at without knocking, the higher the octane of the fuel being tested.
What element is added to table salt?
Goiter is a problem with the thyroid gland, most commonly caused by an iodine-deficiency disease. You can prevent or cure it by eating seafoods which are rich in iodine, or by using iodized table salt.
Element no longer used in car gasoline?
Lead used to be commonly added to gasoline as an octane booster, but due to its environmental and health risks, it has been phased out and is no longer used in car gasoline.
Why is ethanol added to gasoline?
Ethanol is added to gasoline to reduce air pollution and greenhouse gas emissions. It helps gasoline burn more cleanly and efficiently, resulting in lower levels of harmful pollutants being released into the atmosphere. Additionally, ethanol is a renewable fuel source that helps reduce the reliance on fossil fuels.
Element added to gasoline in 70's?
Lead was added to gasoline in the 1970s as an anti-knock agent to improve engine performance. However, it was later discovered that lead in gasoline was harmful to both human health and the environment, leading to its phase-out in the following decades.
What element is added to salt?
chloride- sodium and chloride make salt and its symbol is NaCl.
