If you’ve pulled into a Chevron or Shell in the Golden State this morning, you probably felt that familiar sting. Even as the rest of the country watches prices tumble toward levels we haven't seen in years, California is still doing its own thing.
The short answer? How much is gas right now in California averages out to $4.21 per gallon for regular unleaded as of mid-January 2026.
It sounds high. It is high. But context matters here. Just a month ago, we were looking at averages closer to $4.38, so things are technically moving in the right direction. If you compare this to the national average, which has dipped to around **$2.81**, the gap feels like a canyon. You're basically paying a "sunshine tax" of nearly $1.40 more per gallon than someone filling up in Oklahoma or Texas.
Breaking Down the Local Numbers
Gas prices aren't a monolith across the state. In fact, driving from one county to another can change your bank account balance significantly.
Stockton is currently one of the cheaper spots, with regular gas hovering around $3.91. Meanwhile, if you’re up in Napa or down in San Luis Obispo, you’re likely staring at $4.40 to $4.46 at the pump. It’s a wild swing for the same 400-mile stretch of coastline.

- San Francisco: $4.27
- Oakland: $4.19
- Sacramento: $4.08
- Fresno: $4.13
- San Diego: $4.41
Honesty time: the "why" behind these numbers is a messy cocktail of taxes, environmental mandates, and a very isolated fuel market. California’s state excise tax alone is about $0.60 per gallon. Add in the sales tax, the underground storage fees, and the carbon programs like Cap-and-Trade, and you’ve added $1.20 to the price before the gas even leaves the refinery.
The Refinery Crisis Looming Over 2026
You might have heard the whispers at the grocery store or on the news about $8 gas.
It sounds like clickbait. However, there’s some serious math behind the fear. Two major refineries—Phillips 66 in Los Angeles and the Valero facility in Benicia—are on the chopping block. Phillips 66 is winding down operations as we speak, and Valero is slated for a potential transition or closure later this year.
Why does this matter? California is a "fuel island." We don't have pipelines bringing in gas from the Gulf Coast. We have to make it here. When we lose 20% of our refining capacity, we either import it on ships (expensive) or deal with shortages (very expensive).

Professor Michael A. Mische from USC’s Marshall School of Business recently released a report suggesting that if these closures hit hard and the state doesn't adjust its regulatory stance, we could see prices spike toward that terrifying $7 or $8 mark by the end of the year. It's a risk assessment, not a guarantee, but it’s enough to make any commuter nervous.
How Much Is Gas Right Now in California Compared to Last Year?
Surprisingly, we are actually doing better than last January.
On average, Californians are paying about 15 to 17 cents less than they were this time in 2025. This is largely thanks to a global dip in crude oil prices and a slight decrease in demand as more people switch to EVs or hybrid models.
But "better than last year" still feels like a loss when the rest of the U.S. is celebrating sub-$3.00 gas. The California Air Resources Board (CARB) has been under fire lately because their Low Carbon Fuel Standard (LCFS) is expected to add even more pressure to the pump. Critics say it could add another 40 to 65 cents per gallon in the coming years. Proponents say it’s the price of breathing cleaner air.

Survival Tips for the 2026 Commute
Waiting for the government to lower the gas tax is a losing game. It’s not going to happen. Instead, you've got to be a bit more tactical with how you refuel.
First, stop using credit cards at the pump if the station offers a cash discount. Many independent stations in the Central Valley, like Ernie’s General Store in Stockton, try to keep prices at "rock bottom" by cutting out the 3% merchant fee. That can save you 10 cents a gallon instantly.
Second, use apps like GasBuddy or Waze, but don't just look for the lowest price. Look for the trend. If prices are dropping in the Bay Area, they’ll usually hit the valley a few days later.
Lastly, check your tire pressure. It sounds like something your dad would nag you about, but in a state where gas is over $4, a 3% increase in fuel efficiency from properly inflated tires actually adds up to a free tank of gas over the course of a year.
Next Steps for Drivers:
- Monitor the Valero Benicia status: If that refinery hits a snag in April, expect an immediate 20-cent jump in Northern California prices.
- Join a wholesale club: Costco and Sam’s Club are consistently 20–30 cents cheaper than name-brand stations right now.
- Track the LCFS updates: Watch for the next CARB meeting; any shift in the "carbon intensity" requirements will lead to a price hike at the pump within weeks.
