OK,... I'll then say we're not getting pure CO2 anymore; the high-octane, far infrared belching, global frying greenhouse grade gas of yesteryear. Its been padded down with additives.
That makes as much sense as the above quote.:-)
You might want to look up hexane, heptane, octane, nonane, decane, etc. They are aliphatic hydrocarbons having 6 to 10 carbon atoms in each molecule chain. Gasoline is a mixture of these short hydrocarbon chains.
Shorter hydrocarbon chains are gases; methane, ethane, propane, butane and pentane. They are fundamentally the same as the liquid hydrocarbon chains that make up gasoline except for their vapor pressure (boiling point).
Much longer hydrocarbon chains make up diesel fuel, oils, heavy oils and paraffin wax. These hydrocarbon chains are so long that all the fun of naming them is gone.:-) Numbers are used instead. As an example, C20H42 to C40H82 covers paraffin wax if I remember correctly.
