More energy ??? I don't think so. My research on the net comes up with:

Gasoline - approx     109,000 BTU / gallon

Diesel           "           128,000 BTU / gallon

AND, diesel engines operate at around 20:1 or higher compression ratio - 
making them way more efficient than a throttled gasoline engine.
