Older gasoline used to contain chemicals such as tetra-ethyl lead. This prevented preignition in the engine and allowed engines to be higher compression. They stopped using it because of heath and environmental issues. Different additives are used in todays car fuels instead. Leaded fuel can still be used in offroad equipment and airplanes.
Gasoline is typically blended with 10% ethanol, which results in an octane rating of 87. This blend is commonly referred to as "gas 87" at fuel stations. The octane rating indicates the fuel's resistance to engine knocking, with higher numbers denoting a higher resistance.
Nothing in paticular - many classes of reaction produce a gas.
This phenomenon is called diffusion.
Portable gas canisters or portable gas cylinders.

Unleaded gas is petrol. In some countries they call it petrol and in others it is called gasoline or gas.
They're usually Regular Unleaded, Mid-Grade Unleaded and Premium Unleaded.
When I STOP AT A STATION i GOT UNLEADED GAS BUT FOUND OUT DIESEL GAS WAS MIXED IN WHAT WILL HAPPEN TO MY UNLEADED TRUCK
There is no risk in mixing super unleaded gas and regular unleaded gas. Super is just given to the name of a gasoline because of cleaning agents and octane added to the gas not because the gas is completely different.
Yes.
No. Do not put unleaded gas in a diesel tank.

The average price of a gallon of regular unleaded gas in 1995 was around $1.15 to $1.20.
regular gas IS unleaded...
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
When you mix regular unleaded fuel and unleaded plus fuel in a gas tank it results in a mixture of fuel with an octane rating higher that regular unleaded fuel but lower than the octane rating of unleaded plus fuel.
