Frequently Asked Questions

Why are the retail pump prices for gasoline and diesel fuel in increments of 0.9 cents?

The pricing of gasoline and diesel fuel at retail service stations to 9 tenths of a cent is most likely a marketing practice. It is similar to other retail pricing of a product at $19.99 rather than $20, or $29.99 rather than $30. EIA does not have information on the origin of this practice.
