People who buy gasoline in cold
places get more bang for their buck than
people buying gas in warm places. Kyle
Norris explains:

Let’s say my friend Ana buys 10 gallons of gasoline in a cold place like the
Canadian tundra. And I buy 10 gallons of gas in the warm state of Florida.
My friend Ana will be able to drive further than I will with those 10 gallons.

That’s because gas expands at warm temperatures. But its energy content
does not.

There’s a gizmo gas stations can put on individual pumps that adjusts for
temperature differences. But each one costs a couple thousand bucks a pop.

Dave Maurer is with the US Government Accountability Office.

“There actually have not been a lot of studies done on the benefits and costs of installing this
equipment. Really what we found is that it’s not really known.”

Right now different states do different things. California has just started a
major study on this topic. But without much research, Maurer said it’s tough
for policy makers to make decisions.
