Louisiana Gas Prices

What drivers in Louisiana are paying this week

Louisiana does not have a published weekly statewide average, so the reference number above is the Gulf Coast (PADD 3) average of $3.702. That regional benchmark fell $0.080 week over week and is $0.567 below the national average of $4.269. Stations in Louisiana typically trade within roughly 20 to 40 cents of the regional figure, depending on distance from the nearest terminal and local taxes.

Louisiana is one of the cheapest states for gasoline in the country. It sits in the middle of the Gulf Coast refining corridor, and the state fuel tax is among the lowest in the nation.

Why Louisiana gas prices land where they do

• More than a dozen refineries operate in the Baton Rouge and New Orleans corridor.
• Lowest-tier state motor fuel tax.
• Pipeline and barge access keeps wholesale prices close to refinery gate prices.

These are structural factors, not daily noise. They explain why Louisiana tends to sit in the same part of the national price range week after week, even when the national average moves. For the general mechanics behind these forces, see our guide on how gas prices are set.

Ways to spend less on gas in Louisiana

1. Membership warehouses such as Costco, Sam’s Club, and BJ’s usually price 10 to 30 cents below nearby branded stations.
2. Stations a few miles off the interstate are often cheaper than the first exit, because they pay less for land and rely on local traffic.
3. Apps that show station-level prices are worth using for the last mile — our numbers give you the regional baseline, they give you the address.
4. Keeping tires at the recommended pressure and removing roof racks can recover 3 to 6 percent of fuel economy, which is worth 10 to 20 cents a gallon at current prices.

How we source Louisiana prices

Every figure on this page comes from the U.S. Energy Information Administration's weekly retail gasoline survey, which reports average retail prices in dollars per gallon including taxes. We rebuild the page every week after the survey is released, so the date on the price panel always matches the data behind it. We do not estimate missing state numbers; where the EIA does not publish a statewide series, we label the regional benchmark instead. Full details are in our methodology and data sources pages.

The bottom line for Louisiana drivers

At the regional benchmark of $3.702 per gallon, a 12-gallon fill-up in Louisiana costs about $44.42. Over a 15,000-mile year at 28 MPG, that implies roughly $1983 in fuel, before any local station discounts.
