Gas Prices by Region
Average retail gas and diesel prices, sourced from the U.S. Energy Information Administration's weekly survey. Pick a region for current prices, a 30 day trend, and a prefilled calculator.
How these regions are organized
Prices are organized in four tiers: a single national average, five PADD supply regions plus several notable subregions, individual states, and major metro areas. PADD stands for Petroleum Administration for Defense District, a supply-chain based geography the US government still uses to track how gasoline actually moves from refineries to retail, and it often explains regional price patterns better than state lines alone since neighboring states in the same PADD tend to draw on the same pipelines and refineries.
Every region shown here breaks its current price out by regular, premium, and diesel, plus a 30 day trend chart for regular gasoline, so you can see not just today's price but whether it's been rising or falling recently, and a calculator prefilled with that region's own price so you don't have to type it in yourself.
Prices also move seasonally across every region tracked here, typically climbing into the summer driving season as many areas require a cleaner, more expensive summer fuel blend and vacation demand rises together, then easing again after Labor Day. Crude oil price swings and refinery disruptions, particularly on the Gulf Coast, can override that normal seasonal pattern in either direction, which is exactly why each region's page includes a rolling 30 day trend rather than just a single snapshot price.

Frequently asked questions
Four factors drive most of the difference: state and local fuel taxes, which range from a few cents per gallon in some states to well over fifty cents in others; special low-emission fuel blends some states require, which cost more to produce; distance from refineries and major supply pipelines, since gasoline generally costs more the farther it has to travel; and local competition and operating costs at the retail level.
PADD stands for Petroleum Administration for Defense District, a set of five geographic regions the US government defined during World War II to organize fuel supply, and the Energy Information Administration still uses the same boundaries today because they map closely to how gasoline actually moves through pipelines and refineries. Prices within a PADD tend to move together since they draw on shared supply infrastructure, even when the states within it differ on tax and price level.
Premium gasoline has a higher octane rating, which requires additional refining steps and different blending, and it also usually carries a higher tax and margin since it's a lower volume, higher margin product for retailers. The price gap between regular and premium is fairly consistent nationally, typically 40 to 60 cents per gallon, even as the base price of regular moves up and down.
The underlying data comes from the US Energy Information Administration's weekly retail gasoline and diesel survey, so a region's current price reflects roughly the last week rather than today specifically. Local prices at an individual station can move daily and will not always match this average exactly.
Use whichever region most closely matches where you actually buy fuel. The national average is useful for a broad estimate or for comparing a trip that crosses many states, but a state or city level price will be far more accurate for local planning, since the gap between the cheapest and most expensive tracked regions commonly exceeds a dollar per gallon.
This site tracks the national average, all five PADD regions plus four PADD subregions, nine individual states, and ten major metro areas, chosen to cover a representative geographic and price spread rather than every state and city. If your exact area isn't listed, the closest PADD region or a nearby state is usually a reasonable stand-in.
Two seasonal factors combine: many areas require refineries to switch to a cleaner, more expensive summer fuel blend intended to reduce smog, and vacation driving pushes demand higher at the same time. Prices generally ease again after Labor Day as refineries switch back to cheaper winter-blend fuel and travel demand drops.
Diesel usually costs somewhat more than regular gasoline, driven by a combination of a slightly higher federal tax per gallon, different refining economics, and demand from freight trucking and industrial use that doesn't track passenger vehicle demand the same way gasoline does. The gap between the two shifts with the seasons rather than staying fixed.
No, these figures cover gasoline and diesel only. If you drive an electric vehicle, use the EV versus gas comparator instead, which works in cost per mile using your own local electricity rate rather than a gas price.
Each region page shows three separate current prices, one each for regular, premium, and diesel, since they move somewhat independently and a vehicle typically only uses one of the three. The 30 day trend chart adds a time dimension on top of that snapshot, tracking regular gasoline specifically since it's what the large majority of vehicles use.
