Price trends and regional differences
What causes fluctuations in motor gasoline prices?
Retail gasoline prices are mainly affected by crude oil prices and the level of gasoline supply relative to demand. Strong and increasing demand for gasoline and other petroleum products in the United States and the rest of the world at times places intense pressure on available supplies. Even when crude oil prices are stable... read more in Gasoline Explained
What causes fluctuations in diesel fuel oil prices?
The retail price of a gallon of diesel fuel reflects the underlying costs and profits (or losses) of producing and delivering the product to customers. The price of diesel at the pump reflects the costs and profits of the entire production and distribution chain, including... read more in Diesel Fuel Explained
Why are gasoline prices higher in some regions than in others?
Although price levels vary over time, average retail gasoline prices are often highest in certain States or regions. Besides taxes, there are other factors that contribute to regional and even local differences in gasoline prices... read more in Gasoline Explained

What are components of retail price of diesel fuel?
The cost to produce and deliver diesel fuel to customers includes the costs of crude oil, refinery processing, marketing and distribution, and retail station operation. The retail pump price reflects these costs and the profits (and sometimes losses) of the refiners... read more in Diesel Fuel Explained
What are fuel surcharges?

Where can I find real motor gasoline and on-highway diesel prices?
Real petroleum prices are computed by dividing the nominal price in a given month by the ratio of the Consumer Price Index (CPI) in that month to the CPI in some "base" period. The Real Petroleum Prices... view interactive chart of real prices in Short-Term Energy Outlook

Data quality and survey methodology
What are the motor gasoline price data collection methods?
Every Monday, retail prices for all three grades of gasoline are collected by telephone from a sample of approximately 800 retail gasoline outlets. The prices are published around 5:00 p.m. ET Monday,... read more
What are the diesel fuel oil price data collection methods?
Every Monday, cash self-serve on-highway diesel prices (including taxes) are collected from a sample of approximately 400 retail diesel outlets in the continental U.S. The sample includes a combination of truck stops and service stations that sell on-highway,... read more
What are motor gasoline sampling and estimation procedures?
The sample for the Motor Gasoline Price Survey was drawn from a frame of approximately 115,000 retail gasoline outlets. The gasoline outlet frame was constructed by combining information purchased from a private commercial source with information contained on existing EIA petroleum product frames... read more
What are diesel fuel oil sampling and estimation procedures?
The respondents reporting to the weekly diesel price survey represent a stratified probability proportional to size (PPS) sample selected from a frame list of retail outlets. The outlet sampling frame was constructed... read more
How reliable are the motor gasoline and diesel fuel oil prices?
The Coefficient of Variation (CV) of the mean, a measurement of variability of the mean price, is calculated as the standard error divided by the mean. As a measure of precision reflecting the error due to sampling, it can also be used to construct a confidence interval for the population mean. For example, a mean price of $1.67 and a CV of 0.004 (.4%) indicates at the 95% confidence level that the population mean price has an upper limit of $1.68 ($1.67 + 1.96*0.004*$1.67) and a lower limit of $1.66 ($1.67 - 1.96*0.004*$1.67).
