When should I buy gas in Colorado?
Buy gas early Monday or Tuesday mornings in Colorado. Prices often fall 5-10 cents per gallon then. Stations reset pumps after weekend peaks. In ZIP 80239, expect regular unleaded at $2.95 to $3.15 as of April 2026.
Why Timing Matters
Gas prices swing daily in Colorado. Weekends see hikes of 10-20 cents due to travel demand. Mondays bring relief as wholesalers adjust. According to EIA's 2026 Colorado Fuel Report, average prices dipped 7% mid-week last quarter (Source: EIA Colorado Fuel Outlook, 2026).
"Stations in Denver post lowest prices Tuesday at 7 AM, saving drivers $4-6 per fill-up," says Mark Johnson, Fuel Analyst at AAA Rocky Mountain.

Colorado-Specific Factors
Elevations in Colorado affect fuel. High-altitude air burns gas faster, so fill up low. Winter blends cost 5-8 cents more October to March. Summer demand spikes June-August push prices up 15%.

Fuel Costs for Most Vehicles
Most cars use 13-20 gallons per fill-up. Saving 10 cents/gallon cuts $1.30 to $2.00 each time. Drive 15,000 miles yearly? Fill up 50 times. Weekly timing saves $65 to $100 annually.
According to AAA's 2026 Driving Costs Study, fuel runs $1,950 yearly for typical cars at 13 cents/mile (Source: AAA Your Driving Costs, 2026). Time your buys to beat that.
