Gasoline, when used in high compression internal combustion engines, has a tendency to autoignite (detonation) causing a damaging engine knock (also called "pinging") noise. Early research into this effect led to the discovery that lead additives modified this behavior led to the widespread adoption of their use in the 1920s and therefore more powerful higher compression engines. The most popular additive was tetra-ethyl lead. Its use continued for decades despite the deaths of several members of the original research teams from lead poisoning. Marketing materials purposely avoided mentioning lead explicitly, and instead "Ethyl" was used. However, with the discovery of the extent of environmental and health damage caused by the lead, and the incompatibility of lead with catalytic converters found on virtually all newly sold US automobiles since 1975, this practice began to wane and it is illegal in the USA and Canada.

What are the benefits of petrol?
The beneifits of petrol is that it fuels your car and it lets it go many kilometres. Petrol is also a fossil fuel and will be around for the next hundred of years. Also petrol doesn't contain lead, unlike the earlier types of petrol which contained lead and can damage your heath. the benefit of petrol is that it gives fuel to your car so it can work and drive kilometers and more.
Volatility of petrol fuel system?
The volatility of a petrol fuel system refers to how easily the fuel evaporates when exposed to air or heat. A highly volatile fuel system may lead to increased vapor emissions, reduced fuel efficiency, and potential safety hazards. Proper maintenance and use of fuel stabilizers can help regulate volatility in petrol fuel systems.
Can you use lead free petrol in 1989 Toyota Cressida GLI6?
Yes, you can use lead-free petrol in a 1989 Toyota Cressida GLI6. This model was designed to run on unleaded fuel, as leaded petrol became phased out in many regions during the 1980s. Using lead-free petrol will not harm the engine and is actually recommended for better performance and emissions control. Always check your owner's manual for specific fuel recommendations.
What is the difference in 4 star and 3 star petrol?
The star rating is no longer used to classify petrol. The star rating was an indication of the percentage of lead present in the fuel. Commercial fuels no longer contain lead.
Why is there lead in petrol?
Lead was added to petrol as an anti-knock agent to improve engine performance. It prevented engine knocking or pinging, which is a metallic pinging noise that can occur in an engine when fuel ignites unevenly. Lead was phased out of petrol due to its harmful effects on human health and the environment.
What is an unleded petrol?
Unleaded petrol is petrol that has not been treated with a lead compound.
Lead content in petrol?

Can you drive without a petrol cap?
While it is technically possible to drive a vehicle without a petrol cap, it is not advisable. Driving without a cap can lead to fuel evaporation, decreased fuel efficiency, and contamination of the fuel system. Additionally, it may trigger warning lights on the dashboard and could potentially result in engine performance issues. It's best to replace a missing petrol cap as soon as possible.
When you fill up with petrol in your peugeot 306 it does not start afterwards why?
If your Peugeot 306 won't start after filling up with petrol, it could be due to a few potential issues. One possibility is that there might be a problem with the fuel system, such as a clogged fuel filter or a failing fuel pump. Additionally, if the petrol cap is not sealed properly, it can lead to a vacuum in the fuel tank, preventing fuel from reaching the engine. Lastly, if water accidentally entered the fuel tank during refueling, it could cause starting issues as well.
Why petrol not used as fuel in stoves?
Petrol is highly flammable and volatile, making it dangerous to use as a fuel in stoves. Its combustion can produce harmful fumes and emissions, posing health risks. Additionally, petrol burns at a higher temperature than is typically needed for cooking, which can lead to food burning or the stove malfunctioning.
Lead was put in petrol to prevent the problem?
TEtro-Ethel Lead (spelling errors my fault) was added to fuel to increase octane.This reduced pre ignition also known as ping.
