Gas prices in Louisiana
EIA does not publish a weekly retail gasoline price for Louisiana. The federal survey prices the district Louisiana sits in, Gulf Coast (PADD 3), at $3.62 per gallon in the week of August 31, 2026, 45 cents below the US average of $4.07. Pump prices inside the district vary around that figure.
On-highway diesel for Gulf Coast (PADD 3) is $5.36, 24 cents below the US diesel average of $5.60. EIA runs the diesel survey for California and the regions only, so every other state carries its district figure here. Refinery proximity is the cleanest example of the cost stack at work.

Louisiana's pump-price cost stack
Every gallon breaks down into five named slices. Applying the shares to the $3.62 figure above, and to Louisiana's own excise rate, the stack looks like this:
Crude / refining / distribution shares estimated from EIA Petroleum Marketing Monthly. Federal excise from FHWA Highway Statistics. State excise from the API Motor Fuel Tax Map and Tax Foundation 2026. [EIA · 31 Aug 2026] [API · 31 Aug 2026]
Border-state comparison
How the neighbours read in the same survey week. Neighbours inside the same EIA district carry the same published figure, which is why several rows can match exactly.
Use the border comparator to compute the per-tank difference where the two states fall in different EIA districts.
