How much energy is there is 1 gallon of diesel fuel?

Answer:

this number is going to be all over the place, but to find an average, the technical name for the quantity you are looking for is called the Lower Heating Value or LHV. Google it, and you will quickly find an average.

I found 45 MJ/kg to be reasonable. LHV is the number used in combustion engines of all kinds, jet, diesel, gasoline...
