More than likely. That's why I just took the top four. It already put us at 80% fuel use, which is higher than what was previoulsy posted (using 28% non-fuel use).
I didn't know for certain what other items may/may not be used for fuel.
I knew kerosene was, but at 0.5%, it wouldn't have mattered if I included it. I figured liquefied refinery gasses were likely to include propane, but wasn't 100% on that, either.
I believe the refinery gases are mostly propane.
Some of the terms are defined here if that helps.
