While it is true that hydrocarbons (LPG/gasoline) follow the "denser = more energy" rule - Ethane, Methane, Propane, Butane, Gasoline are increasingly denser and have more BTU - EtOH is not a hydrocarbon. EtOH, while having less energy content (21.2 MJ/L vs 34.8 for gaso and 38.6 for diesel), is more dense (0.79 g/cm3 vs 0.71–0.77 for gasoline).

So yeah, for hydrocarbons, heavier is more, not necessarily true for other compounds. |
