Eye-Popping Prices Spotted in Old Town
A WhatsThePriceOfGas.com reader recently shared a photo of a Shell gas station in San Diego's historic Old Town neighborhood displaying some jaw-dropping numbers on its price sign. As of March 31, 2026, the station was charging $6.49 per gallon for regular unleaded, $6.69 for Plus grade, $6.79 for V-Power premium, and $6.99 for Renewable Diesel. These prices represent some of the highest we've documented in the San Diego market this year and serve as a stark reminder of the ongoing price disparities across the country.
How San Diego Compares to the National Average
To put these numbers in perspective, the current national average for a gallon of regular gasoline sits at approximately $3.17. That means drivers filling up at this particular Old Town Shell station are paying nearly double what most Americans pay at the pump. For a typical 15-gallon fill-up, San Diego drivers at this location would shell out $97.35, compared to roughly $47.55 at the national average price. That's an extra $49.80 per tank—a difference that adds up quickly for commuters and families managing tight budgets.
Why California Gas Prices Are So High
Several factors contribute to California's consistently elevated fuel costs. The state's gas tax stands at 77.9 cents per gallon, one of the highest in the nation. Beyond direct taxation, California's environmental programs add significant costs to every gallon sold. The Low Carbon Fuel Standard (LCFS) and the state's cap-and-trade program together add an estimated 40 to 60 cents per gallon to fuel prices. These programs are designed to reduce carbon emissions and promote cleaner fuel alternatives, but they undeniably impact what consumers pay at the pump. Additionally, California requires a special gasoline blend that's more expensive to produce and limits the number of refineries that can supply the market.

San Diego's Position in California's Gas Market
Even within California's expensive fuel landscape, San Diego consistently ranks among the priciest markets in the state. The region's proximity to the Mexican border, combined with its relative distance from major California refineries concentrated in the Los Angeles area, can contribute to higher transportation and distribution costs. Tourism-heavy areas like Old Town also tend to see premium pricing, as gas stations in high-traffic destinations often charge more than suburban or rural locations. Savvy local drivers typically know to shop around, as prices can vary significantly even within a few miles.
Tips for San Diego Drivers Looking to Save
If you're facing these premium prices in San Diego, there are several strategies to help soften the blow at the pump. Using gas price comparison apps can help you locate the cheapest stations in your area—prices can vary by 50 cents or more between stations just blocks apart. Warehouse clubs like Costco consistently offer lower prices for members, often 30 to 50 cents below nearby competitors. Paying with cash can sometimes save you an additional 10 to 20 cents per gallon at stations that offer cash discounts. Finally, combining trips, maintaining proper tire pressure, and avoiding aggressive driving can all improve your fuel efficiency and stretch every expensive gallon a little further. While nobody can control what stations charge, smart shopping habits can make a meaningful difference in your monthly fuel budget.
