gasoline
liquid oilThis entry defaults to DESNZ's 'Petrol (average biofuel blend)' figures, which match real UK forecourt fuel. For petrol with no bioethanol content, '100% mineral petrol' is a separate entry with its own numbers. IPCC's 2006 global default for motor gasoline is an NCV of 44.3 MJ/kg and CO₂ of 69,300 kg/TJ. As a US cross-check, the EIA reports 120,214 Btu/gal and 9.46 kg CO₂/gal. These alternative figures are shown for reference only and are never blended into the main value.
