A Globe for the Price of a Gallon

Field notes

The site combines a globe view with a searchable table covering 225 places, including U.S. states and Canadian provinces and territories. Its tools turn the data into comparisons and trip estimates using distance, vehicle efficiency, and local price. The explanatory layer separates crude, refining, distribution, and tax, and gives special attention to the crack spread as a reason pump prices can move independently of crude oil.
