Gas Prices in Killeen, TX Today

Killeen drivers are paying around $3.22 per gallon for regular unleaded as of late March 2026, among the cheapest in Central Texas and nearly 70 cents below the national average of $3.91. The presence of Fort Cavazos (formerly Fort Hood), the largest active-duty US Army installation in the world, fundamentally shapes Killeen's fuel economy in ways that benefit civilian drivers too.

How Fort Cavazos Keeps Killeen Fuel Prices Low

Fort Cavazos is home to roughly 35,000 soldiers plus tens of thousands of family members and civilian employees. The base operates its own commissary and exchange system, including on-base gas stations (AAFES) that sell fuel at significant discounts to military ID holders, often 30–40 cents below local pump prices. Civilian stations surrounding the base know their primary competition isn't other gas stations; it's the AAFES pump on post.

This creates a ceiling on how high civilian station prices can go. A station in 76544 near the main gate charging $3.60 would simply lose all non-urgent military traffic to the base exchange. The competitive pressure from AAFES is invisible to most price-tracking tools but very real in the local market.

Bell County also uses conventional gasoline rather than the reformulated blend required in the Dallas-Fort Worth area, which saves 5–8 cents per gallon compared to DFW prices. That difference compounds with the AAFES competition effect.

Where to Find the Cheapest Gas in Killeen

• 76542, Central and south Killeen, highest station density in the city and the most competitive pricing corridor along Fort Hood Street and US-190
• 76541, North Killeen, older commercial area with independent operators that price aggressively for the local market
• 76543, West Killeen near Walmart and major retail corridors, Murphy USA and similar discount operators typically anchor the cheap end here
• 76544, Area near the Fort Cavazos main gate, high traffic volume from military personnel keeps prices competitive despite the on-post alternative
• 76549, East Killeen toward Copperas Cove, lower density but worth checking, some outlier deals in this corridor

The Murphy USA at the Walmart on US-190 in 76543 is a reliable low-price anchor and consistently prices at or near the bottom of the Killeen range.

The Military Community Price Dynamic

Killeen has a higher-than-average concentration of budget-conscious consumers. Military families, particularly junior enlisted soldiers, are among the most price-sensitive fuel customers in any market, and stations competing for that business keep margins thin. This isn't charity; it's market arithmetic. When 40% of your potential customer base has access to discounted on-post fuel, you have to price competitively to capture any of it.

That dynamic makes Killeen one of the few Texas cities where the civilian fuel market essentially self-regulates toward lower prices without requiring high income or warehouse club density.

Copperas Cove Comparison

Copperas Cove, just west of Killeen, often runs within a penny or two of Killeen prices given shared market dynamics and Bell/Coryell county fuel blend parity. If you're near the western edge of 76549, it's worth checking both cities before deciding where to stop.

With crude prices elevated due to the Iran/Hormuz situation, Killeen's structural cheapness provides a real buffer. Even at current elevated levels, Killeen prices are likely to remain well below the state average through the spring.
