The DLA fixed its standard fuel price at rates that were often much higher than what the airlines were paying â sometimes $1 or more a gallon.

Propane is measured by the gallon so propane is priced per gallon. During the 2011-2012 heating season propane prices ranged from $2.74 to $2.88 per gallon, meaning that a 500-gallon tank cost between $1,100 and $1,150 to fill. Propane compared to other energy sources. That propane prices have increased over the last 10 years does not mean that, compared to other sources of energy it is necessarily more expensive.
