No, It was added to gas as a "constant fix" for older cars that didn't have hardened valves
Lead replacement substitute for older cars use manganese or sodium nowadays

What is flammable hydrocarbon gas called?
octane
Element used in gas to stop knocking?
Octane prevents pre-detonation or pinging in high compression engines. They used to use Lead in the form of TetraEthelLead, but since Lead was banned they have gone to more expensive techniques of refining and blending various fractions of the oil that raise effective octane number without adding any one specific chemical. IIRC, for a few years after lead was banned various refineries tried switching to other heavy metals than lead that weren't banned, but none really worked out. I can't remember what was tried.
How can the volume of gas be increased if the pressure is constant?
I wonder that by increasing temperature it will lead to a higher pressure.
Increase the pressure of a gas by?
Both compressing and heating a gas will increase its pressure.
What type of gas does a 99 accord lx v6 use?
Well 98-2002 are recommended to use regular gas octane of 87..
Do you get better gas mileage by car if you use higher octane gas?
Yes, higher octane gas does give higher gas mileage for your car. However, the increase in gas mileage may not as great as the increase in the price of the higher octane gas.
Does high octane gas increase mileage?
Not unless the engine using it was specifically designed for it. Gas mileage takes many things into consideration, and if a car is designed to use standard octane gas, the use of high octane gas will not increase the car's mileage - it is just a way of figuratively blowing dollar bills out of the tailpipe.
Can you use octane boost in lawn mower?
No reason to use it. It does not increase power output. Mowers are designed to run on regular octane gas, and do not need higher octane numbers.
What element was found in 1922 by Thomas Midgley?
He found lead to increase octane leaves in gasoline
What petrol reduces air pollution?
Unleaded. Lead was used to increase the octane rating and improve performance. Not sold with lead in now, in the UK
How much octane does regular gas have?
There is no octane in gasoline... it is the equivalent of octane.
What is meant by 'unleaded gas'?
In the 1940s or 50s, gas companies started adding lead to gasoline. This increased the octane and lubricated the internal parts of engines. Then in the 1970s lead was removed for environmental reasons.
What are two ways to increase a fuel's octane rating?
Octane rating is simply a relative measure of how much octane (which is a chemical substance) is contained in gas. The only way to do it properly is to buy higher octane gas. But buying higher than what your manual recommends is completely pointless. Contrary to popular opinion, you will NOT get more power, you will NOT get better mileage, and it will not run your engine cleaner.
What gas octane do Honda CR-V's use?
The gas octane that would be the best in a Honda CR-V from 2009 is 87 octane. Higher octane gas will improve its performance, but it is only necessary to have 87.
Who still sells gas without ethenal?
I do not believe it can be unless you buy avgas which is 100 octane with lead. Thank the EPA
Can you use premium gas or super unleaded gas in a street motorcycle?
Most all motorcycles when tuned in properly run much better on gas containing an octane rating of at least 90 to 94. Higher octane such as the 98 octane sold as racing fuel at some locations is not recommended unless your engine has been set up to run such high octane fuel as it can increase the temperature of the cylnder/heads and cause excessive wear..
Can use 89 octane gas in passat?
You can use whatever octane you want, generally you shouldn't have to go to higher octane unless your car requires it. If your decidin to go higher because you feel a better power increase this is a sign you need tune up
