gasoline
liquid oilDefaults to the DESNZ 'Petrol (average biofuel blend)' variant (matches real UK forecourt fuel, per research-notes §6 pitfall 5). DESNZ also lists '100% mineral petrol' (density 741.84 kg/m³, NCV 44.65 GJ/tonne, GCV 47.0 GJ/tonne, 2.33984 kgCO2e/L). IPCC 2006 global default (Motor Gasoline) NCV 44.3 MJ/kg, CO2 69,300 kg/TJ. EIA US cross-check 120,214 Btu/gal, 9.46 kg CO2/gal — never averaged with the above.

CO₂ and CO₂e are separate — never derived from each other.
Energy density
Energy per unit of mass or volume.
Assumptions
- density: assumed gasoline density 746.204 kg/m³ at 15 °C (fuel-properties basis)
- heating value basis: energy on LHV/NCV basis, 8.926 kWh/L
- heating value basis: energy on HHV/GCV basis, 9.423 kWh/L
