Well Gasoline is common and used by everyone in cars etc... Nitromethane is more rarely used as a fuel and is ussually just an additive for Drag Racing etc (gasahol)...... I have been doing some online research: Methanol (CH3O3) is most commonly used in producing other chemicals/gases such as the future hydrogen fuels that our future cars may run on. I have been doing some online research if you feel like reading... I learned a lot myself If anyone else wats to know here you go:

Methanol (CH3O3) is produced from natural gas in large commercial facilities in a two step process. The first step is to convert the feedstock natural gas into a synthesis gas stream consisting of CO, CO2, H2O and hydrogen. This is usually accomplished by the catalytic reforming of feed gas and steam. Partial oxidation is another possible route. The second step is the catalytic synthesis of methanol from the synthesis gas. Sounds like a pain in the butt huh????

Now to Gasoline: To break it down easy, Gasoline is a product of crude oil/petroleum. Oil contains hydrocarbons. The oil is distilled (basically boiled) and different gases are able to be extracted because of their different boiling points:

From lower(lighter) to higher(heavier): Methane, Butane, Propane etc...

Napthas (used to make solvents, paint thinners etc...)

GASOLINE (C7H16 through C11H24)

Kerosene

Diesel

Lubricating oils

Greases

Tar

If I missed anything significant let me know....
