Gas Prices in Fontana, CA Today

Fontana drivers are paying roughly $4.85–5.10 per gallon for regular unleaded in late March 2026, notably below the California statewide average of $5.36 and sometimes 40–50 cents cheaper than what coastal Los Angeles or Orange County drivers are paying at the same moment. The Inland Empire's distance from coastal real estate markets, its high station density along major freight corridors, and its massive warehouse and logistics industry create a gas price environment that's genuinely different from the rest of Southern California.

Why the Inland Empire Undercuts the Coast

The price gap between Fontana and Santa Monica isn't primarily about taxes, those are the same statewide. It's about retail economics. Coastal real estate costs translate directly into higher fuel station operating overhead. A station on Pacific Coast Highway in Malibu is paying dramatically more per square foot than one on Sierra Avenue in Fontana, and some of that cost passes through to pump prices.

Beyond real estate, Fontana sits at the junction of I-10 and I-15, two of the heaviest freight corridors in the western United States. The truck traffic in this area is enormous, and stations catering to freight drivers compete hard on diesel and keep overall competitive pressure high across all fuel grades. A Fontana station that tries to charge coastal prices will lose customers immediately to the station across the street.

The Warehouse District Advantage

Fontana and the broader I-10/I-15 interchange area host one of the largest concentrations of warehouses and distribution centers in the country, Amazon, UPS, FedEx, and dozens of others operate large facilities here. Fuel stations around those warehouse complexes, particularly along Cherry Avenue, Citrus Avenue, and the Baseline Avenue corridor, run some of the cheapest prices in the state. These stations are built to handle high volume; they're not trying to extract margin from each customer.

The key insight: stations in the western Fontana industrial zone (ZIP 92335) and the areas around the I-15/I-10 interchange (92316) consistently come in at the low end of Inland Empire pricing.
