When all factors are considered in DoE's formula, the energy efficiency or equivalent fuel economy of electric vehicles increases, being calculated in miles per the petroleum-equivalency factor of 82,049 Wh/gal rather than miles per the usual gasoline gallon equivalent of 33,705 Wh/gallon, for the purposes of CAFE credits to manufacturers.

A 20 lb (9.1 kg) steel propane cylinder. This cylinder is fitted with an overfill prevention device (OPD) valve, as evidenced by the trilobular handwheel. Propane (/ ˈ p r oʊ p eɪ n /) is a three-carbon alkane with the molecular formula C 3 H 8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid.
An imperial fluid ounce is 1 ⁄ 20 of an imperial pint, 1 ⁄ 160 of an imperial gallon or exactly 28.4130625 mL. A US customary fluid ounce is 1 ⁄ 16 of a US liquid pint and 1 ⁄ 128 of a US liquid gallon or exactly 29.5735295625 mL, making it about 4.08% larger than the imperial fluid ounce. A US food labeling fluid ounce is exactly 30 mL.
For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...
Of their eight-cylinder petrol engines, all Volkswagen Group V8 engines are primarily constructed from a lightweight cast aluminium alloy cylinder block (crankcase) and cylinder heads. They all use multi-valve technology, with the valves being operated by two overhead camshafts per cylinder bank (sometimes referred to as 'quad cam').
A 1 inch tall uranium fuel pellet is equivalent to about 1 ton of coal, 120 gallons of crude oil, or 17,000 cubic feet of natural gas. [15] In light-water reactors , 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 ...
Roughly 72 liters (19 U.S. gal) of gasoline is derived from a 160-liter (42 U.S. gal) barrel of crude oil. [10] Material separated from crude oil via distillation, called virgin or straight-run gasoline, does not meet specifications for modern engines (particularly the octane rating; see below), but can be pooled to the gasoline blend.
The United States federal excise tax on gasoline is 18.4 cents per gallon and 24.4 cents per gallon for diesel fuel. [ 16 ] [ 17 ] Proceeds from the tax partly support the Highway Trust Fund . The federal tax was last raised on October 1, 1993, and is not indexed to inflation , which increased 111% from Oct. 1993 until Dec. 2023.
