diesel
liquid oilDefaults to DESNZ 'Diesel (average biofuel blend)' (UK forecourt-representative). DESNZ also lists '100% mineral diesel' (density 830.565 kg/m³, NCV 43.027 GJ/tonne, 2.66155 kgCO2e/L) and 'Gas oil' (red/off-road diesel, 853.971 kg/m³, NCV 42.569 GJ/tonne, 2.75541 kgCO2e/L). IPCC 2006 Gas/Diesel Oil NCV 43.0 MJ/kg, CO2 74,100 kg/TJ. EIA US cross-check 10.19 kg CO2/gal — never averaged.
