EIA Weekly On-Highway Diesel Survey - week of August 31, 2026
Diesel cost per gallon in Texas
Read this as a district figure, not a state figure. The EIA weekly on-highway diesel survey prices the United States, its districts and California, and nothing else. It does not price Texas. The number above is Gulf Coast (PADD 3), series EMD_EPD2D_PTE_R30_DPG, and it is the closest published federal figure for Texas. We do not estimate a price for Texas from it. 3 of Texas's neighbouring states sit in the same district and therefore show the same price below.
EIA does not publish a weekly on-highway diesel price for Texas. The federal survey prices the district Texas sits in, Gulf Coast (PADD 3), at $5.360 per gallon in the week of August 31, 2026 (series EMD_EPD2D_PTE_R30_DPG), $0.24 below the US average of $5.599. Pump prices inside the district vary around that figure.
Diesel tax breakdown
Tax rates: Federation of Tax Administrators state motor fuel table and state revenue departments. Not EIA data. The percentage is against the EIA figure shown above, which is a district figure unless Texas is surveyed directly.
Neighbouring states
Neighbours in the same EIA district carry the same published figure. A matching price here means the federal survey shows no measured gap across that border, not that pumps are identical.
What shapes the diesel price in Texas
Texas sits in the cheapest EIA diesel district. The Gulf Coast refining complex, centred on the Houston Ship Channel, is the largest in the world and processes over five million barrels a day of crude. Texas also levies one of the lowest state diesel taxes in the country. High interstate freight density, with I-10, I-20, I-35 and I-40 all crossing the state, creates intense retail competition among truck stops. Sunbelt dispatchers route fuelling through Texas whenever deadhead or repositioning allows.
The trip calculator starts at $5.36/gal, the EIA figure above. Change it to the price you actually see at the pump for a real answer.
