The lower energy content of LPG by liquid volume in comparison to gasoline is due mainly to its lower density. Never encourage someone to vomit or try to get water down the throat of an unresponsive person. The CAA did not specifically require MTBE. 25 Gasoline production would not surpass kerosene production until 1916.

The Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) requires gasoline for automobile use to have 27.5% of ethanol added to its composition. If a person washes it off quickly, gasoline usually does not cause significant skin complications. By 1941, principally through the efforts of the Cooperative Fuel Research Committee, the number of grades for aviation fuels was reduced to three: 73, 91 and 100 octane. On resumption of regular engine use, the buildup may or may not be eventually cleaned out by the flow of fresh gasoline. People who work with machinery have a higher risk of health problems because they have daily exposure to gasoline, gasoline vapors, or other fuels, such as diesel and kerosene.

Heinz Guderian and his Panzer divisions consumed nearly 1 U.S. gallon per mile (2.4 L/km) of gasoline on the drive to Vienna. Octane rating is measured relative to a mixture of 2,2,4-trimethylpentane (an isomer of octane) and n-heptane. Three different ethanol blends are sold in the Netherlands—E5, E10 and hE15.  The word is a derivation from the word "gas" and the chemical suffixes "-ol" and "-ine" or "-ene"..

"Ban on leaded petrol 'has cut crime rates around the world, "More than 20% of SA cars still using lead-replacement petrol but only 1% need it", "Petrol for older cars about to disappear", "MMT Increases Octane While Reducing Emissions", "EPA Comments on the Gasoline Additive MMT", "Directive 2009/30/EC of the European Parliament and of the Council of 23 April 2009", "Protocol for the Evaluation of Effects of Metallic Fuel-Additives on the Emissions Performance of Vehicles", "Government to take a call on ethanol price soon", "India to raise ethanol blending in gasoline to 10%", "Removal of Reformulated Gasoline Oxygen Content Requirement (national) and Revision of Commingling Prohibition to Address Non-0xygenated Reformulated Gasoline (national)", "How much carbon dioxide is produced by burning gasoline and diesel fuel? The yield of gasoline may be doubled by converting higher Anti-knock agents may be added to further increase the octane With some companies required to stock 14 grades of aviation fuel, none of which could be interchanged, the effect on the refiners was negative. , British refiners originally used "motor spirit" as a generic name for the automotive fuel and "aviation spirit" for aviation gasoline.
