The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. Simple calculations of the BTU values of the ...
The largest component of the average price of $2.80/gallon of regular grade gasoline in the United States from 2012 through 2021, representing 54.8% of the price of gas, was the price of crude oil. The second largest component during the same period was taxes—federal and state taxes representing 17% of the price of gas.

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). [96] About nine percent of ...
The first federal gasoline tax in the United States was created on June 6, 1932, with the enactment of the Revenue Act of 1932, which taxed 1¢/gal (0.3¢/L). Since 1993, the US federal gasoline tax has been unchanged (and not adjusted for inflation of nearly 113 percent through 2023) at 18.4¢/gal (4.86¢/L).
Using EPA 2018 Fuel Economy Guides assumptions for national average pricing of $2.56/gal regular gasoline and $0.13/kWh [42] we can calculate a vehicle that is rated at 84 MPGe or 40 kW/100 Mi efficiency and has a 16.5 kW EV battery of which 13.5 kWh is usable for electric driving with an advertised range of 33 miles per charge.
Tight refining supply has kept the gap wide between wholesale gasoline futures and retail prices, currently at about $1.25 a gallon, far exceeding the average of 88 cents over the past five years.
Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...
