Pure #1 diesel has about 4% less energy content than pure #2 diesel. Keep in mind, that most areas don't go to a full #1 blend either. Granted, other properties (like cetane rating, etc.) change as well, but especially on common rail diesels like mine, energy content is the main property that matters. Personally, I think a lot of people blame the fuel when it's actually the temperature.
