Gas Prices in California
Gas prices in California are the highest in the continental U.S., and it isn’t close. In the week of Oct. 12, 2026, regular averaged $6.10 a gallon in the EIA’s survey, about $1.77 above the national average and roughly $1.65 more than a year earlier. On a 15-gallon fill-up, that’s about $26 more than the typical American driver pays. Below I explain why California is different, how its gas tax compares with its neighbors, and which savings I think are worth your time.

Why gas costs more in California
- Its own gasoline. California requires a cleaner-burning blend known as CARB gasoline. Few refineries outside the state make it, so when a California refinery has problems, the state can’t simply bring in ordinary gas from Nevada or Arizona. That’s the main reason prices here can jump so quickly.
- Fewer refineries. Phillips 66 closed its Los Angeles-area refinery in late 2025, and Valero announced plans to close its Benicia refinery in 2026. Each closure means more fuel has to be shipped in, and imported fuel takes time to arrive when supply gets tight. Expect that to keep California prices jumpy for a while.
- Taxes and climate programs. California’s state taxes and fees add 73.6¢ a gallon (Tax Foundation, July 1, 2026), and the excise part is adjusted every July 1. The cost of the state’s cap-and-trade and Low Carbon Fuel Standard programs is also built into the pump price. Taxes explain part of the gap, not all of it: California pays about $1.03 more than the West Coast average outside the state, while its tax is 34 to 55 cents higher than its neighbors’.

California’s price problem, and what you can do about it
Prices dropped about 12 cents in the week of Oct. 12, a bigger drop than in most of the country. That’s welcome, but at $6.10 California is still in a league of its own, and diesel at $8.09 is even further out of line. I wouldn’t read one good week as the start of a big slide. With fewer refineries and a fuel blend few others make, prices here can swing quickly when something goes wrong at a refinery.
My practical advice: don’t drive across town to chase a few cents, but do use the discounts tied to things you already do, like a warehouse club membership, grocery fuel points or paying with debit. On a 15-gallon tank, 10 cents off saves $1.50 per fill-up, or about $78 a year if you fill up every week. If you have a road trip coming, price it first with the gas trip cost calculator. — Nathan Brooks
What to watch next
The Benicia refinery. Valero’s planned closure in 2026 would leave California even more dependent on imported fuel, and that usually means bigger price swings when anything goes wrong.
Best ways to save on gas in California
- Costco. California has more Costco warehouses than any other state, and their pumps are often among the cheapest in each area. If you already have a membership, this is the first place to look. Costco gas guide.
- Ralphs and Food 4 Less fuel points. Both are Kroger stores, so grocery spending earns Kroger fuel points (100 points = 10¢ off per gallon). If you shop there anyway, it’s an easy discount. I wouldn’t switch grocery stores just for the points. How Kroger points work.
- Vons, Albertsons, Safeway and Pavilions “for U” rewards. Same idea at the Albertsons-owned chains: grocery points turn into cents off per gallon at the chain’s fuel stations and participating partner stations. Check the app to see which stations near you count.
- Look for a cash or debit price. Many California stations post a lower price for cash or debit, sometimes 10¢ or more a gallon. It needs no app and no membership.
- Fill up before you cross the state line. If you’re driving in from Arizona or Nevada, where gas is usually cheaper, arrive with a full tank.

Propane in California
The EIA doesn’t survey home propane prices in California, so the only real benchmark is what local suppliers quote you. Most California homes heat with natural gas or electricity, and propane is mainly a rural and mountain-area fuel. Without a state average to compare against, I’d get quotes from at least three suppliers and ask about pre-buy plans before winter. For context, you can compare with prices in the 38 states the EIA does survey.
- Grill and RV tanks: where to refill propane and exchange vs. refill.
- Home tanks: tank sizes and how long a tank lasts, and a fill-up cost calculator.
- Help with heating bills: California LIHEAP (state profile) can help eligible households pay for heating fuel, including propane.
Quick answers
Why is gas so expensive in California?
California requires a special cleaner-burning gasoline that few refineries make, has the highest state gas taxes and fees in the country (73.6¢ a gallon as of July 1, 2026), and has lost refining capacity as refineries close.
Where is the cheapest gas in California?
Prices are usually lower in the Central Valley and inland areas than in the Bay Area, Los Angeles or near the coast. Warehouse clubs like Costco are often the cheapest option in each city.
When does California’s gas tax change?
California adjusts its gas excise tax every July 1 for inflation.
