Diesel prices by state and EIA district

US average $5.599/gal, EIA Weekly On-Highway Diesel Fuel Price survey, week of August 31, 2026, series EMD_EPD2D_PTE_NUS_DPG.

There is no federal fifty-state diesel table, so this page does not fake one. The EIA weekly on-highway diesel survey prices the United States, the five PADDs, three PADD 1 sub-districts, West Coast less California, and California. That is 9 district figures plus one state. The 49 states without a series carry their district figure below, named on every row, which is why groups of neighbouring states show the same price. The genuinely state-level column on this page is the tax column.

The other 49 tiles show the figure for the EIA district that state sits in, which is why neighbouring states carry identical prices. Hover a tile to see which district.

Why diesel prices vary across the country

State diesel taxes

The federal diesel tax is 24.4 cents a gallon everywhere. State rates run from 8 cents in Alaska to over 100 cents in California once cap-and-trade compliance is counted. Pennsylvania's 74.1 cents is the highest in the contiguous US.

The tax spread alone accounts for a large share of the California to Texas gap. The rest is refining and transport cost. Unlike the price column, these rates really are state-level, which is why the table below pairs them with a district price rather than hiding the difference.

Proximity to refineries

Gulf Coast states are closest to the nation's largest refining capacity, so lower transport cost feeds through to a lower district price. West Coast states import more finished product by tanker, which adds logistics cost.

PADD 5 is structurally isolated from PADD 3 by the Rockies. No pipeline carries finished diesel west across the mountains, which is exactly why EIA treats the West Coast as its own district and splits California out of it.

CARB diesel specification

California requires diesel meeting California Air Resources Board specifications, with stricter limits and additional refining steps beyond the federal ULSD requirement. CARB diesel costs more to produce and must be kept segregated throughout distribution, which is part of why EIA prices California separately from the rest of the West Coast.

Winter blend requirements

Northern states require winter-grade diesel, winterized or blended with kerosene, to prevent gelling in extreme cold. That adds seasonal cost from October through March and shows up in the Midwest and Rocky Mountain district series as a recurring winter pattern.

FAQ: state and district diesel prices

What state has the cheapest diesel?+
The EIA weekly on-highway diesel survey cannot answer that. It publishes a price for the United States, five PADDs, three PADD 1 sub-districts, West Coast less California, and California. It publishes nothing for the other 49 states, so there is no federal state-by-state diesel ranking to quote and this page does not print one. What the survey does rank is districts: in the week of August 31, 2026, Lower Atlantic (PADD 1C) was cheapest at $5.276 per gallon and West Coast (PADD 5) dearest at $6.497. Gulf Coast refining capacity and low state fuel taxes are why the southern-central states sit at the bottom of that table.
Why is California diesel so expensive?+
California is the one state EIA prices separately for diesel, and in the week of August 31, 2026 it read $7.218 per gallon against a US average of $5.599. Three reasons. California Air Resources Board diesel specifications require refining steps beyond the federal ULSD standard and a separate distribution chain. California's combined state diesel tax is the highest in the contiguous US once cap-and-trade compliance is counted. And in-state refinery capacity is constrained relative to demand, so California imports more finished product than any other state, with no pipeline route from the Gulf Coast.
How often do diesel prices change?+
Retail diesel prices at the pump change daily with crude futures, regional refinery operations and local competition. EIA runs one survey a week: prices are collected Monday morning and released the same afternoon ET, so the figures on this site move once a week and are dated by survey week rather than by the day you read them. State tax rates change less often, typically once or twice a year, usually when a state indexes its rate to inflation or wholesale prices.
What is the federal diesel tax?+
The federal diesel tax is 24.4 cents per gallon, set under the Highway Revenue Act. That is higher than the 18.4 cents per gallon federal gasoline tax. Both are flat per-gallon levies rather than percentages, so neither rises automatically with fuel prices, and neither has changed since 1993. Some states tax diesel above their gasoline rate, others apply the same rate to both.
Which states have the highest diesel taxes?+
Pennsylvania leads the contiguous states at roughly 74 cents per gallon once the state excise, oil franchise fee and sales component are combined. California's combined effective diesel tax exceeds 100 cents once cap-and-trade compliance cost is included. Illinois, Indiana, Washington and New York make up the rest of the high-tax tier. At the other end, Missouri, Mississippi, Alabama and Oklahoma sit under 20 cents. These are statutory rates from the Federation of Tax Administrators, not EIA data, and they are the one genuinely state-level number on this page.
