Where are you at? I haven't seen leaded gas or petrol since I was in grade school. They used to call it "regular" and there was that and diesel until they decided the lead in gasoline was bad for us and started offering unleaded. Eventually, every gas station in the U.S. phased regular gas out. If you have an old car from the days of leaded petrol, you'll probably have to put unleaded in it some time (unless you live in a country where they still have leaded gas at the stations). If you put unleaded gas in an old car, you can get a fuel additive to protect the engine from the harsher fuel. Over time, using unleaded in an old engine can cause some of the gaskets to dry out and start leaking. It won't hurt just one time, but it's an accumulative effect if you do it all the time.
Autos made within the past 25 years or so have a fuel filler opening that only permits the insertion of the small unleaded gasoline nozzle, if that is the required fuel for your auto. The larger nozzles of leaded gasoline (still used in airplanes) and diesel will not fit.
Use of leaded gasoline in modern automobiles causes the catalytic converter to malfunction and fouls the spark plugs. This, in turn, alters the operation of the engine in ways that can rapidly lead to damage. Rapidly, in this case, can mean as little as fifteen minutes. Even if the engine is undamaged, it will cost hundreds of dollars to replace the catalytic converter.
unleaded
in petrol we have 2 types.they are 1.leaded petrol 2.unleaded petrol in leaded petrol we have lead compounds so we call it as leaded petrol. in unleaded petrol we do not have lead compounds. the use or advantage of unleaded petrol is it does not emit harmful gases in to the environment. but leaded petrol emits harmful gases. cracking process takes place in unleaded petrol. cracking means it is a process of converting harmful gases into harmless gases. but this cracking process cannot be done in leaded petrol bcoz lead compounds decomposes the catylsts used in cracking process
Unleaded Premium
I don't think there is a way to visually tell the difference between leaded and unleaded fuel. However, leaded gasoline has become "extinct" and it is more likely that you have unleaded gasoline in the can.
1998 I think you mean what year did unleaded petrol start in Britain.
boom...thats what you get...dummie Leaded fuel would ruin the O2 sensors and the catalytic converters.
Unleaded, most vehicles manufactured post 1983, particularly Japanese are made to run on Unleaded
The valves, particularly the exhaust valves, will become damaged quite quickly
In the UK, the most common petrol types are: Ordinary unleaded - 95 RON Super unleaded - 98 RON Leaded Four Star - 98 RON
unless im mistaken they havent used leaded fuel since at the latest the 60's...
leaded gas has lead in it, unleaded does not Leaded petrol (or gas as you Americans quaintly call it) contained a chemical called Lead Tetraethyl to improve its performance. It was then discovered that the amount of lead given out by cars (or automobiles) was making city air dangerous to breathe and so its use has been forbidden. All petrol/gas is now unleaded and "green". Car engines have needed to be redesigned to allow them to burn the unleaded fuel.
Unleaded fuel was introduced in the mid 1980s, it depends what engine it has, if it needs leaded fuel you will need a new engine
