7.2 lbs weight in a US gallon of #2 diesel. A Deere 8320 made 18.93 HP-hr-gal at max rated. That would be 0.380 lbs fuel per hr per HP. The 720/730 diesels were ahead of their time making 1799HP per gallon per hour or 0.400 lbs per HP per hour. Best engine to date is a turbo two stroke marine diesel at 0.260 lbs per hp per hr.That's 27.7HP per gallon per hr.Over 50% efficiency too.

So 37.2% fuel efficiency on a farm diesel while running all those accessory loads and emissions equipment ain't shabby.
