Gas Prices in Oxnard, CA Today

Oxnard is Ventura County's largest city, and gas prices here are running close to the California average of $5.36 per gallon for regular unleaded in March 2026. But Oxnard's geography creates an interesting split market: stations near the harbor and Channel Islands Boulevard cater to boats, tourists, and weekend traffic and price accordingly, while the agricultural and industrial corridors inland compete harder for the working-class drivers who fuel up every day.

Oxnard's Unusual Fuel Market

Few California cities have as wide a gap between their premium and budget fuel markets as Oxnard. On the harbor side, marinas and coastal recreation businesses drive a tourist-heavy customer base that's less price-sensitive. On the inland side, Oxnard has one of the largest concentrations of agricultural workers in Southern California, plus a significant military-adjacent population from Naval Base Ventura County (Port Hueneme is just south). That creates a demanding, price-aware base of daily drivers.

The result: you can find gas in Oxnard that's 50 cents per gallon apart within three miles of each other. The harbor and the Target/Home Depot retail corridor along Vineyard Avenue might run $5.60+, while stations on Saviers Road and in the older residential grid run closer to $5.20–5.30. That spread is larger than most California cities of comparable size.

Ventura County imposes its own sales tax layer on fuel, but the rate is slightly lower than Los Angeles County. That gives Oxnard a modest structural cost advantage over the broader LA metro.

Where to Find Cheaper Gas in Oxnard

Target the inland and working-class corridors, not the coastal retail zones:

• 93030, Central and east Oxnard, Saviers Road corridor; this is where price competition is highest, with a mix of independents and branded stations competing for the daily driver
• 93033, South Oxnard near the navy base and Port Hueneme border; military community adjacency keeps prices honest, some of the most competitive stations in the county
• 93035, Oxnard Shores / Channel Islands Harbor; expect premium pricing here, not the place to fill up unless you're stuck
• 93036, North Oxnard / Rose Ave corridor; newer development with some warehouse-style retailers, worth checking for competitive pricing

The Costco in Oxnard on Gonzales Road is a major asset for local drivers and consistently runs 30–45 cents below the Oxnard street average. It's also one of the less congested Costco fuel stations in Ventura County, the Camarillo and Thousand Oaks locations get heavier traffic. If you're a Costco member, this should be your default stop.

The Agricultural Shift Angle

Oxnard's agricultural economy means heavy commercial traffic, trucks, equipment haulers, farm vehicle operators, who buy in volume and are extremely price-sensitive. That buyer pressure tends to keep margins thin at the stations they frequent, particularly on Saviers and in the Gonzales Road corridor. Regular passenger vehicles benefit from that same competitive dynamic.

Diesel prices in Oxnard are also meaningfully competitive compared to the rest of Ventura County for the same reason, the commercial farming economy demands it. If you drive a diesel vehicle, Oxnard is one of the better places in the county to fill up.

Spring Outlook

California's summer blend fuel transition, typically beginning in late March, will push prices up 10–20 cents across the state over the next few weeks. Oxnard will follow that statewide trend. Filling up in the next week or two is practical.
