Gas Prices in Lakewood, CO Today

Lakewood drivers are paying around $3.60 per gallon for regular unleaded as of late March 2026, right at the Colorado state average, and notably cheaper than what you'll find if you drift east into Denver proper or west along I-70 toward the mountains. Lakewood sits in the sweet spot: a dense west Denver suburb with real station competition, away from the tourist corridor that inflates prices on weekends when ski traffic surges up the canyon.

The I-70 Corridor Premium, and Why Lakewood Avoids It

This is the central story of gas prices in the west Denver metro: the I-70 mountain corridor is one of the most price-inflated stretches of highway in Colorado. Stations at Idaho Springs, Georgetown, and Silverthorne know exactly who their customers are, people who forgot to fill up in Denver, or who are returning from a ski weekend and are nearly on empty. Prices at those stations regularly run $0.50–$0.80 above Denver metro averages.

Lakewood is the last real "local" zone before the canyon begins. The stretch of Colfax Avenue (US-40), Alameda Avenue, and Wadsworth Boulevard running through Lakewood proper has the station density and local customer base that keeps prices honest. The moment you pass through Golden and start climbing, that calculus changes.

Colorado's gas tax is 22 cents per gallon, lower than many Western states, but the state requires specific fuel blends in the Denver metro area (the Denver-Boulder-Greeley corridor uses CARB-adjacent reformulated specifications due to high-altitude air quality concerns). These cleaner-burning blends cost 5–10 cents more per gallon to produce than conventional fuel, which is part of why Colorado runs above national averages despite a low tax rate.

Where to Find the Cheapest Gas in Lakewood

The west and south edges of Lakewood generally beat the corridors closer to Denver. Stations near Bear Creek and the Belmar shopping area see consistent local traffic that keeps margins tight.

Search by ZIP:

• West Lakewood / Green Mountain, 80227, 80228, residential areas, less tourist traffic, competitive independents
• Central Lakewood / Belmar, 80226, 80232, high station density, Costco at Wadsworth/Yale nearby
• East Lakewood / Edgewater border, 80214, 80215, urban transition zone, mix of prices

Costco at the Belmar area (80226/80232 boundary) is consistently the cheapest option in the entire west Denver metro and is worth the detour if you're already on the west side.

Timing Your Fill-Up Around Ski Season

From November through late March, gas prices in the greater Denver metro, including Lakewood, tick up modestly due to increased mountain weekend demand. The pattern is consistent: Thursday and Friday see prices edge up as ski-bound drivers fill tanks, then ease slightly by Monday. If you can fill up Tuesday or Wednesday morning, you'll generally catch the weekly low.

Spring and fall are structurally cheaper in Colorado: summer-blend transition is done, ski season demand is off, and refinery turnarounds are typically scheduled for spring rather than summer. Late April through May is historically one of the best windows to fill up in the Denver area.

The Real Savings Move

If you live on the Lakewood/Lakewood-Wheat Ridge border or anywhere in the western suburbs, filling up before heading toward I-70 rather than after you return is the single highest-value habit you can build. The difference between a fill-up in Lakewood and one in Idaho Springs can exceed $20 on a standard tank.
