Alabama gas prices

See Alabama fuel infrastructure See your local terminals in Alabama

Alabama consistently ranks among the cheapest states for gasoline in the country. Its proximity to Gulf Coast refineries in Louisiana, Texas, and Mississippi means fuel doesn't have to travel far to reach local pumps, keeping transportation costs low. The state also maintains one of the lowest combined gas tax rates in the nation, currently around 29 cents per gallon including federal excise taxes allocated at the state level.

As part of PADD 3, the Gulf Coast petroleum district, Alabama benefits from being in the same supply region as the largest concentration of refining capacity in the United States. This gives the state reliable access to abundant fuel supply, which helps keep prices stable even when other parts of the country see sharp increases due to supply disruptions.

Diesel prices matter in Alabama too, given the state's significant agricultural sector and its role as a freight corridor connecting the Southeast to the Gulf Coast. Interstate 65 and I-20 carry heavy truck traffic through the state, and diesel cost fluctuations directly affect shipping and farming costs across the region.

Why is gas so cheap in Alabama?

Alabama benefits from low state gas taxes and its close proximity to Gulf Coast refineries. Fuel doesn't need to be shipped long distances, and the state sits within PADD 3, the region with the most refining capacity in the country. These factors combine to keep pump prices well below the national average.

How do hurricane seasons affect Alabama gas prices?

Gulf Coast hurricanes can temporarily disrupt refinery operations in neighboring states like Louisiana and Texas, which supply much of Alabama's fuel. During major storms, prices can spike for a few weeks as refineries shut down or reduce output. However, Alabama typically recovers quickly once operations resume.

What drives diesel price changes in Alabama?

Diesel demand in Alabama is closely tied to agriculture, freight, and manufacturing. Seasonal farming activity and changes in trucking volume along major interstate corridors can influence local diesel prices. National crude oil price swings and refinery maintenance schedules also play a significant role.
