Fuel additives in the United States are regulated under section 211 of the Clean Air Act (as amended in January 1995). The Environmental Protection Agency (EPA) requires the registration of all fuel additives which are commercially distributed for use in highway motor vehicles in the United States, [8] and may require testing and ban harmful additives.
The white gas sold today is a similar product but is produced at refineries and has a very low benzene content, benzene being a human carcinogen. [5] Though Coleman fuel has an octane rating of 50 to 55 and a flammability similar to gasoline, it has none of the additives found in modern gasoline.
In the U.S., most consumer goods bear pre-tax prices, but gasoline prices are posted with taxes included. Taxes are added by federal, state, and local governments. As of 2009, the federal tax was $0.049 per liter ($0.184/U.S. gal) for gasoline and $0.064 per liter ($0.244/U.S. gal) for diesel (excluding red diesel). [97]
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
MOSCOW/KYIV (Reuters) -Russian gas exports via Soviet-era pipelines running through Ukraine came to a halt on New Year's Day, marking the end of decades of Moscow's dominance over Europe's energy ...

Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.
