Huntington Beach Costco Gas at $5.20 as Diesel Nears $7

Regular gas and diesel both rose in the latest price check relevant to Huntington Beach. AAA’s Orange County averages, dated July 31, 2026, reached $5.664 per gallon for regular gasoline and $6.993 for diesel.

Regular gas was up 0.9 cents from the previous day and 7.0 cents from a week earlier. Diesel rose 2.8 cents day over day and 10.1 cents over the week.

Huntington Beach Costco price remains below county average

A Huntington Beach Costco station listing refreshed August 1 showed regular gasoline at $5.199 per gallon. That station-level price was about 46.5 cents below the Orange County AAA regular-gas average.

The comparison does not represent a citywide Huntington Beach average. AAA’s figure covers Orange County, while the Costco price applies only to the station at 7562 Center Ave and can change when the station updates its listing. Costco also requires a current membership card to fuel up.

The Huntington Beach Costco location does not sell diesel, so its regular-gas price cannot be used to compare both fuels at the same station.

Diesel prices show a wide local spread

A Huntington Beach-area diesel listing showed prices ranging from approximately $6.399 to $7.49 per gallon. The listing reported an average of about $6.80 across 17 stations within five miles.

That listed spread of more than $1 per gallon matters most to drivers who buy larger quantities. A commercial vehicle taking on 25 gallons could pay roughly $27 more at the high end of that range than at the low end, before accounting for differences in tank size or fuel use.

What higher fuel costs may mean locally

For commuters and households, the latest increases add to the cost of regular driving and weekend travel. Diesel changes can be especially important for contractors, delivery operators, service fleets, restaurants that rely on deliveries and other businesses using heavier vehicles.

Fuel is one operating cost those businesses may need to manage when setting delivery charges, service prices or travel budgets. The available data does not document specific local business price changes, so any effect on customers remains something to watch rather than a confirmed local reaction.

Drivers should treat the county average as a benchmark, not a quote for every Huntington Beach pump. Checking several stations before filling up may reveal meaningful differences, particularly for diesel.
