Gasoline or petrol is the most common fuel used in light motor vehicles today.
This specialized fossil fuel is designed for four-stroke engines like the ones found in common cars. Gasoline allows for quick starting, fast acceleration, easy combustion and quiet operation, according to the University of Michigan website on fossil fuels. The hydrocarbons contained in gasoline and its production of carbon dioxide when burned contributes to pollution, smog and global warming. Although it is the most readily available fuel, it is considered to be a temporary source of fuel because of its cost, environmental effects and limited resources.
