FOR REFERENCE
Gasoline contains about 43.2 megajoules per kg (115,500 BTU/US gal)
The heating value of propane is 7% higher than gas at 46.4 MJ/kg however, due to its lower density, it has a 21% lower volumetric energy density (91,690 BTU per US gallon).
Diesel has a heating value of 43.1 MJ/kg, similar to gasoline, However, due to its even higher density, diesel offers an even higher volumetric energy density (128,700 BTU/US gal)
So, diesel's volumetric (by gallon) energy density is 11% more than gas, 40% more than propane.
