Gas Prices in Springfield, MO Today

Springfield drivers are paying around $3.25 per gallon for regular unleaded in late March 2026, comfortably below the national average of $3.91. Missouri is one of the cheapest states for gasoline in the country, and Springfield, the third-largest city in the state, sitting at the crossroads of I-44 and US-65, benefits from both Missouri's favorable tax structure and an unusually competitive local fuel retail market.

Missouri's Gas Tax Advantage

Missouri charges 19.9 cents per gallon in state gas taxes, among the lowest rates in the country, trailing only Alaska. The state has historically underfunded road infrastructure as a result, but for drivers filling up, it's straightforward savings. Missouri's low gas tax is a significant reason why the state consistently ranks near the bottom of national price averages, a position Springfield benefits from as much as Kansas City or St. Louis.

Springfield also sits roughly equidistant from the refinery infrastructure serving the Midwest. The Mid-Continent region pipeline network, fed by refineries in the Kansas City area, Coffeyville (KS), and Wood River (IL), reaches southwest Missouri through a series of product terminals. Springfield's wholesale rack prices benefit from this connectivity, staying close to true Midwest market pricing without the geographic haul premiums that affect more remote markets.

The Kum & Go vs. Casey's Dynamic

Here is the locally specific story of Springfield's gas market: the city is contested territory between two Midwest convenience store chains that use fuel as a competitive weapon. Kum & Go (headquartered in Des Moines, owned by Maverik since 2023) and Casey's General Stores (headquartered in Ankeny, IA) both have significant Springfield footprints and compete aggressively for local customers.

Both chains run their own loyalty apps with fuel discount programs, and in a market like Springfield where both are fighting for share, the discount offers can be substantial, 10–25 cents per gallon off when you accumulate points or link a grocery purchase. Casey's Pizza rewards program, in particular, has an effective fuel discount component that regular Casey's customers use systematically. Download both apps, use whichever offers the better deal on a given week, and you'll consistently pay less than the posted price.

The I-44 Corridor Premium

I-44 passes through Springfield connecting St. Louis to Joplin and Oklahoma. The truck-stop and highway-facing stations along the I-44 corridor through Springfield price to capture travelers who are passing through and won't comparison shop. The Campbell Avenue exit cluster and the Glenstone exit in particular run 10–20 cents above what you'll find two blocks off the highway. If you're just passing through, that extra two-minute drive to an off-highway station is worth it.

Where to Find the Cheapest Gas in Springfield

South Springfield and the residential corridors away from the I-44 frontage are consistently cheaper than the highway and the commercial spine of Glenstone.
