Hydrocarbons (alkanes)...
Gasoline is mostly Heptane (7 chain alkane)..... if you look at the gas pump you will see some are mixed with Octane (8 chain alkane) for better performance...

Basic Gasoline "Fossil" fuel consists mainly of "hydrocarbons" i.e. (Carbon + Hydrogen) with 8-12 carbon atoms per molecule and later benzenes are added to increase the octane rating mainly for internal combustion engines. Distillation of crude oil makes natural gasoline with almost no octane ratings. Olefins in gasoline formulates CnH2n
Well you can go on and on with many different additions and subtractions from the base gasoline but to be short the basic gasoline comprises of mixture of olefins, paraffin’s, aromatics & naphthene. Whatever the formulation maybe the main corrosive chemicals thiols and hydrogen sulfide must be removed before it can be used. These days to increase the Octane ratings up to 25% anhydrous Ethanol with minimum purity of 95% is added to the refined gasoline. Ethanol is a biofuel (Alcohol) derived from Corn in the US and from Sugarcane in Brazil and many other countries.

fuel oil, which is normally considered crude, is mainly maide of hydrocarbons. hydrocarbons are compounds with carbon and hyrdogen. for ethane contains 2 carbons and 6 hyrodgens. Butane contains 4 carbons, and 10 hydrogens. the list goes on and on.
