Current average diesel price in California
As of July 30, 2025, the average regular gas price in California is $4.481 per gallon, according to AAA. This is the average price across the state, and individual county prices will vary.
While this price is relatively high, it is important to note that gas prices have been steadily decreasing over the past year. A year prior, in July 2024, the average price of gas in the US was $3.498 per gallon, and in June 2022, oil prices peaked at nearly $120 per barrel.
The price of diesel fuel in California is likely to be higher than the average gas price, as diesel fuel typically costs more than gasoline. The exact price of diesel fuel in California is difficult to ascertain, as it may vary by county and is subject to frequent changes.
However, based on the available information, it can be estimated that the current average price of diesel fuel in California is likely to be between $4.50 and $5.00 per gallon. This estimate takes into account the average gas price in California, as well as the typical price difference between gasoline and diesel fuel.
It is worth noting that the price of diesel fuel can be influenced by various factors, including supply and demand, geopolitical developments, and inventory levels. Additionally, the prices can vary significantly between different states, with a difference of up to $2 per gallon between the most and least expensive states.

Comparison to the national average
As of 28 July 2025, the average price of diesel fuel in California is $4.481 per gallon, according to AAA. This is the price for regular gas, which is the most common type of fuel.
In comparison, the average price of diesel fuel in the United States as a whole is $3.140 per gallon as of July 30, 2025. This price is down from $3.185 per gallon a month prior, and from $3.498 per gallon a year prior.
The price of diesel fuel in California is higher than the national average. The difference in price is due to a variety of factors, including taxes, transportation costs, and local demand. California typically has higher fuel prices than other states due to its unique blend of gasoline, which is designed to reduce air pollution and meet the state's strict emissions standards.
The price of diesel fuel can vary widely from state to state, with the most expensive state typically costing about $2 more per gallon of regular fuel than the least expensive state. California is often one of the more expensive states for diesel fuel, due in part to its high cost of living and strict environmental regulations.
While the president of the United States cannot control fuel prices, they can enact policies that influence them. For example, policies that encourage domestic fuel production or reduce fuel taxes can lower prices at the pump. Additionally, events such as the 2022 peak in oil prices due to the Russian sanctions can cause widespread increases in fuel prices.

How diesel prices vary across California
As of my last update on July 28, 2025, the average price of diesel fuel in California was $4.481 according to AAA. However, it's important to note that diesel prices can vary across different counties and regions within California. Several factors influence the variation in diesel prices across the state.
Geographic location plays a significant role in price discrepancies. Diesel prices tend to be higher in metropolitan areas, such as Los Angeles and the San Francisco Bay Area, due to higher demand and operating costs. Conversely, rural or less populated counties may experience slightly lower diesel prices. Additionally, the presence of major transportation hubs, such as ports or distribution centers, can impact local diesel prices due to increased demand from freight and logistics operations.
Market competition among fuel retailers also contributes to price variations. In areas with multiple gas stations competing for customers, prices may be more competitive and fluctuate frequently. On the other hand, regions with limited fuel retail options may experience more stable but potentially higher prices due to reduced competition.
Regional differences in taxation and local regulations can further influence diesel prices across California. Local sales taxes and environmental surcharges may vary across counties, leading to noticeable differences in fuel prices for consumers. Additionally, the cost of living and economic factors unique to each region can play a role in price variations.
Another factor to consider is the availability and adoption of renewable diesel fuel. California has been a leader in the adoption of renewable diesel, which is produced from biomass and offers environmental benefits. The demand for renewable diesel may impact price dynamics across the state, particularly in regions with a strong focus on sustainability and eco-friendly initiatives.
It's important for consumers and businesses to stay updated with the latest fuel price information, as diesel prices in California can fluctuate over time due to various economic, political, and environmental factors. By monitoring trusted sources and staying informed about regional variations, individuals and organizations can make informed decisions regarding fuel purchases and transportation logistics.

Factors influencing diesel prices
The average price of diesel fuel in California is currently $4.481 per gallon. This price is influenced by several factors, which are outlined below.
Crude Oil Cost and Supply
The cost of crude oil is a major determinant of diesel prices. Crude oil must be refined into gasoline and diesel fuel, a process that comes with its own costs. These costs vary depending on the specifications of the final product and any additives used. For instance, summer gasoline has a low vaporization rate to reduce air pollution, which increases production costs.
Demand and Supply
The demand and supply of diesel fuel influence its price. The worldwide demand for diesel has been steadily increasing, particularly in China, Europe, and the United States. Regional demand also plays a role; seasonal swings in demand from farmers can impact diesel prices. For example, during fall and winter, the demand for heating oil affects diesel fuel prices as heating oil and diesel fuel are produced simultaneously.
Transportation Costs
Transportation costs contribute to diesel prices, with areas farther from the Gulf Coast, a major source of U.S. diesel fuel production, generally facing higher prices. The West Coast, especially California, experiences higher diesel prices due to supply issues and taxes. California's liquid fuels market is relatively isolated and relies primarily on in-region refinery production, making it costly to transport supplies from outside the region during refinery outages.
Taxes
Various taxes are levied on diesel fuel, including federal excise taxes, state taxes, sales taxes, and local/municipal government taxes. As of January 1, 2024, the total state taxes and fees for on-highway diesel fuel in California averaged 96.32 cents per gallon, significantly higher than the average for all 50 states (34.74 cents per gallon). Diesel taxes are generally higher than gasoline taxes because diesel is mostly used by heavier trucks, which cause more wear and tear on highways.
Market Conditions
Local market conditions, such as the location and ownership of retail outlets, also influence diesel prices. Refiners may own some outlets, while others are independent businesses purchasing diesel fuel on the wholesale market or for resale, leading to variations in costs and retail prices.
