Temperature of fuel affects how much you get...

This is in the category of you learn something new every day. I did not stop to realize that when the temperature rises consumers actually get less gasoline per gallon than is the set standard of 231 cubic inches per gallon. It appears this could change in the very near future according to this report in our local daily newspaper:

Almost a century ago, the industry and regulators agreed to define a gallon of gasoline as 231 cubic inches at 60 degrees. But as the mercury rises and gasoline expands, it takes more than a gallon of gas to produce the same amount of energy as a regular gallon in colder weather.

U.S. gas retailers ignore the temperature swings and always dispense fuel as if it’s 60 degrees. As a result, gas is an average of about five degrees warmer than the federal standard, according to a study analyzed by Dick Suiter of the National Institute of Standards and Technology. But it’s worst in southern and western states where the temperatures are the most consistently warm.

While I'd hope that this could be dealt with on a state level, as an example what Hawaii did, this will probably become a political issue which will mean years of dragging it out in the federal government...
