Gas Prices in Aurora, CO Today

Aurora drivers are paying around $3.55–3.65 per gallon for regular unleaded in March 2026, a few cents below the Colorado state average of approximately $3.60 and well below the national average of $3.91. As the third-largest city in Colorado and a major eastern suburb of Denver, Aurora benefits from strong station density and consistent competition along its main commercial corridors, particularly along Colfax Avenue, Iliff Avenue, and the I-225 corridor.

Why Aurora Prices Slightly Undercut Central Denver

Denver's urban core commands a premium at the pump for the same reason it does in most city centers: land is expensive, throughput is constrained, and operators can charge more because customers are already there. Aurora's east-metro geography means lower real estate costs for station operators, more highway-adjacent stations competing for interstate and suburban traffic, and less captive-audience pricing.

Colorado doesn't have a state-specific fuel blend requirement as stringent as California's, which means the state can source gasoline from multiple pipelines and refineries, primarily the Suncor refinery in Commerce City (just north of Denver and Aurora) and Frontier Oil's Cheyenne facility. The Suncor refinery is a direct supplier to Denver-metro terminals, and Aurora stations draw from the same distribution network. Short supply chains keep prices competitive.

The Buckley Space Force Base Effect

One specific dynamic in Aurora is the competition near Buckley Space Force Base on the city's east side. Military installations with on-base fuel service create a price signal that off-base civilian stations have to respond to, military members have access to below-market fuel prices on base, so stations just outside the gate price aggressively to compete for the surrounding residential and commercial traffic. The E. Sixth Avenue and Buckley Road corridor benefits from this competitive pressure.

Where to Find the Cheapest Gas in Aurora

• West Aurora / Near Denver border, 80010, 80011, dense older commercial strip; some of the lowest prices in the city, with a mix of independents and discounters on Colfax
• Central Aurora, 80012, 80013, mid-range; Iliff Avenue and Parker Road corridors have good selection and reasonable competition
• Southeast Aurora / Southlands, 80015, newer development around the Southlands mall area; Costco in this corridor is the best single price in southeast Aurora for members
• East Aurora, 80017, near Buckley; station competition near the base keeps prices honest on the east side

Colorado's Spring Price Pattern

Colorado typically sees a 20–30 cent seasonal increase in spring as refineries switch from winter to summer blend formulations. That transition is happening now, layered on top of the crude price increase driven by the Iran/Strait of Hormuz situation. The combination is pushing Colorado prices up from their winter lows, though the state remains comfortably below the national average.

Colorado's Suncor refinery provides a degree of local supply insulation that states without in-state refining don't have. When national crude prices spike, Colorado's price increase is often slightly muted compared to markets that rely entirely on pipeline imports.

Best Strategies for Aurora Drivers

The Costco fuel station in southeast Aurora (Southlands area) and the Sam's Club locations in the metro are the consistent low-price anchors. For non-members, stations along Colfax Avenue west of Tower Road and on Iliff Avenue near I-225 price competitively for commuter traffic. Avoiding stations at I-70 and I-225 interchange exits during peak hours is a consistent money-saver, interchange stations run 8–12 cents above the surrounding market during high demand periods.
