diesel
liquid oilDefaults to DESNZ 'Diesel (average biofuel blend)' — UK forecourt diesel, which contains biodiesel. For diesel with no bio content see '100% mineral diesel'; for off-road/red diesel see 'gas oil'. Both are separate entries with their own numbers. 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.
