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 gas price prior to reform was $0.10 US per liter with the quota of 100 liters per month per passenger car. The reform raised the price to $0.40 US per liter and later reduced the ration to 60 liters per month. The price for over-quota consumption and the imported cars were $0.70 US per liter.
This is complicated by the different energy content of fuels such as petrol and diesel. The Oak Ridge National Laboratory (ORNL) states that the energy content of unleaded petrol is 115,000 British thermal unit (BTU) per US gallon (32 MJ/L) compared to 130,500 BTU per US gallon (36.4 MJ/L) for diesel.

Petrol reached an average of 166.7p per litre on Sunday, close to its record of 167.3p set on March 22. That was a day before Chancellor Rishi Sunak implemented a 5p per litre cut in fuel duty.
The AA said the average price of a litre of the fuel reached 151.21p on Thursday. Skip to main content. Sign in. Mail. 24/7 Help. For premium support please call: 800-290-4726 more ...
Due to the higher density, diesel fuel offers a higher volumetric energy density: the density of EN 590 diesel fuel is defined as 0.820 to 0.845 kg/L (6.84 to 7.05 lb/US gal) at 15 °C (59 °F), about 9.0-13.9% more than EN 228 gasoline (petrol)'s 0.720–0.775 kg/L (6.01–6.47 lb/US gal) at 15 °C, which should be put into consideration when ...
Low speed diesel engines like the MAN S80ME-C7 have achieved an overall energy conversion efficiency of 54.4%, which is the highest conversion of fuel into power by any single-cycle internal or external combustion engine. [9] [10] [11] Engines in large diesel trucks, buses, and newer diesel cars can achieve peak efficiencies around 45%. [12]
In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/ ... Diesel fuel = 18,500 BTU/lb (0.0119531 kW⋅h/g)
