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.
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
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 Premium
the reason unleaded is used today is because people got lead poisoning from leaded gasoline. theres not much difference environmental wise.
Unleaded gas is petrol. In some countries they call it petrol and in others it is called gasoline or gas.
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
Leaded fule has real lead in it, because the valves or piston rings needed this extra lead for lubrication. Usually it is older cars that use leaded fuels, such as cars made before 1996. Any vehicle equipped with a catalytic converter cannot use leaded fuel.
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
