Costco pumps in Missouri
Missouri has some of the cheapest fuel prices in the US, with an average diesel price of 0.89 per liter between February and May 2025.
Costco is a popular destination for fuel in Missouri, with its low prices and convenient layout attracting crowds.

The layout also includes a separate lane for vehicles that finish fuelling before those in front of them, allowing them to exit smoothly without causing congestion.

Diesel price fluctuations
Diesel prices in Missouri have been subject to fluctuations over time, influenced by various market factors and demand dynamics. As of May 2025, data indicates that diesel prices in the state experienced a period of relative stability with some minor variations.
From February 17, 2025, to May 26, 2025, the average diesel price in Missouri was recorded at 0.89 per liter. During this period, the price did not deviate significantly, maintaining a range between a minimum of 0.87 per liter on May 5, 2025, and a maximum of 0.92 per liter on February 24, 2025. These values represent a relatively narrow fluctuation, indicating a stable diesel price trend during this specific timeframe.
Several factors can influence diesel price fluctuations in Missouri. One of the primary factors is the global price of crude oil, which affects the cost of petroleum products worldwide. When crude oil prices rise, diesel prices tend to increase as well. Market dynamics, such as supply and demand, also play a crucial role in price fluctuations. Changes in demand for diesel fuel, influenced by factors like seasonal variations or economic activity, can lead to shifts in diesel prices.
Additionally, government policies and regulations can impact diesel prices. Taxes, subsidies, and environmental regulations can all influence the cost of diesel fuel. Local factors specific to Missouri, such as supply chain disruptions or regional demand variations, can also contribute to price fluctuations within the state.
It is worth noting that diesel prices can vary across different regions of Missouri. Local supply and demand conditions, as well as the presence of competitive gas stations, can lead to price variations within the state. For instance, the presence of a new Costco station in Missouri, offering lower gas prices, has attracted crowds of customers. Such market competition and variations in local pricing strategies can contribute to diesel price fluctuations across different areas of the state.
In summary, diesel price fluctuations in Missouri are influenced by a combination of global, national, and local factors. While the average diesel price maintained stability during the period from February to May 2025, with minor variations, it is subject to change based on market dynamics, government policies, and regional factors unique to the state. Monitoring diesel prices over time and staying informed about market trends and industry developments can provide valuable insights into understanding and anticipating future price fluctuations in Missouri.
