As summer 2025 approaches, the price of gasoline remains a key concern for travelers across the United States. With fluctuating prices at the pump, it’s essential for road trip planners and daily commuters alike to be aware of where fuel costs are the most affordable.
While certain states are known for higher prices due to geographical and economic factors, others continue to provide relief for drivers, offering lower prices than the national average. This article will explore the top ten states offering the most affordable gasoline prices this summer and highlight the states with the lowest diesel prices for those who drive diesel-powered vehicles.
Mississippi and Oklahoma Lead the Way for Gasoline Prices
In the summer of 2025, Mississippi takes the lead with the lowest regular gasoline price at $2.716 per gallon. Close behind are Oklahoma and Tennessee, with prices of $2.746 and $2.781, respectively. These states have consistently ranked among the most affordable in terms of gas prices, making them attractive destinations for travelers seeking to save money on fuel. For those planning long road trips or daily commutes, these states offer significant savings compared to the higher prices seen in places like California and Hawaii.
Mississippi’s affordable fuel prices are attributed to a combination of factors, including its lower overall cost of living and access to refinery infrastructure. Similarly, Oklahoma benefits from its proximity to oil production areas, allowing the state to offer cheaper prices compared to states farther from energy sources.
Texas: A Dual Leader in Gasoline and Diesel Prices
Texas, known for its vast oil reserves, holds the fourth spot for the lowest regular gasoline prices at $2.787 per gallon. However, the state’s biggest distinction lies in its diesel prices, which are the lowest in the nation. At $2.787 per gallon for diesel, Texas surpasses all other states, making it an ideal destination for those with diesel-powered vehicles. In fact, the state’s fuel costs are often more competitive than regular gasoline prices in other regions, particularly when compared to places like Mississippi, where gasoline prices remain lower, but diesel is more expensive.
While Oklahoma and Mississippi remain prominent for regular gasoline, Texas consistently outperforms in the diesel category, benefiting from a robust supply chain and efficient infrastructure. Despite the greater demand for gasoline in the U.S., the relatively small number of diesel vehicles on the road leads to fluctuating prices that are not as volatile as those for regular gas.
Louisiana and Alabama: Affordable Options for Travelers
Following closely behind Texas in gasoline prices are Louisiana and Alabama, both offering prices just above $2.79 per gallon. Louisiana, with its access to both Gulf Coast refineries and major shipping channels, continues to provide low-cost fuel. Similarly, Alabama benefits from its geographical proximity to key oil-producing regions, making it a go-to state for drivers looking to save on fuel costs.
Both states consistently rank among the top ten for the lowest gasoline prices, reflecting their continued efforts to maintain affordability despite rising costs elsewhere. With prices hovering around $2.80 per gallon, travelers passing through these southern states can fill up without breaking the bank.
Arkansas, Kentucky, South Carolina, and Missouri: Other States to Watch
In addition to the leading states for low gasoline prices, a few other states are also noteworthy for offering significant savings in 2025. Arkansas, Kentucky, South Carolina, and Missouri all make the top ten list for gasoline prices, with each state offering prices ranging from $2.80 to $2.85 per gallon. While these states may not have the absolute lowest prices, they still provide competitive rates compared to more expensive regions across the country.
For example, both South Carolina and Missouri share a price of $2.853 per gallon, making them among the most affordable states to refuel. These states’ locations along major highways make them popular stops for cross-country travelers, offering not only cheap fuel but also convenient refueling stations.
Diesel Prices: Texas, Oklahoma, and Mississippi Dominate
While gasoline prices tend to grab the most attention, diesel prices are an essential consideration for drivers with diesel-powered vehicles. In 2025, Texas continues to dominate this category with the lowest diesel price at $2.787 per gallon. Oklahoma and Mississippi follow closely behind, with prices of $2.746 and $2.716 per gallon, respectively. The disparity between diesel and gasoline prices reflects the fact that only a small percentage of vehicles in the U.S. use diesel fuel, thus affecting supply and demand dynamics.
For drivers of diesel-powered vehicles, the savings in these states are substantial, as the price difference can make a notable impact on long-term fuel costs. Despite the greater overall availability of gasoline vehicles, diesel drivers benefit from a select group of states offering cheaper alternatives.
