West Coast (PADD 5) Gas Prices — What You Need to Know

Regular gasoline on the West Coast is currently $5.117 per gallon, up $0.134 from last week as summer driving season pushes demand higher. This price level is notably above the national average and reflects the unique supply and regulatory environment of PADD 5. Typical West Coast prices run higher than inland states due to state taxes, environmental fuel blends, and limited refinery capacity in the region.

A 15-gallon fill-up at today's West Coast price costs $76.76, roughly $2 more than a week ago. Diesel drivers are paying a premium spread of $0.950 per gallon above regular gas, which is wider than typical national spreads and reflects tighter diesel supply in California and the Pacific Northwest. West Coast prices consistently run 50–80 cents above the national average, making fuel one of the largest variable expenses for regional commuters.

What Drives Gas Prices in West Coast (PADD 5)?

West Coast gas prices are shaped by California's strict Low Carbon Fuel Standard and environmental fuel blend requirements, which limit supply to cleaner-burning but more expensive formulations unavailable in most other states. The region has only a handful of refineries—primarily in the San Francisco Bay Area and Los Angeles area—and limited pipeline connectivity to inland sources, meaning the West Coast largely relies on its own refining capacity and occasional imports. State gasoline taxes in California (around 68 cents per gallon) and Washington and Oregon taxes also add substantially to pump prices compared to federal tax alone.

From Crude Oil to the Pump

Brent crude is trading at $96.12 per barrel, while WTI is at $88.58, and these benchmark prices typically flow through to West Coast pumps with a lag of 2 to 6 weeks depending on refinery operations and inventory levels. The current $7.54 spread between Brent and WTI reflects global supply dynamics, and Brent is the more relevant benchmark for West Coast refiners since they can source crude globally. If crude prices remain stable or decline, drivers could see modest relief at the pump within the next month, but any refinery maintenance or supply disruptions could offset those gains.

💡 Money-Saving Tip: West Coast drivers should consider using fuel rewards programs at grocery chains like Safeway and Kroger, which can save 10–20 cents per gallon during promotional periods, and fill up early in the week when prices tend to be slightly lower than weekends. Where available, trying ethanol blends like E85 at participating stations can yield modest savings, though they offer fewer miles per gallon; also monitor GasBuddy or app-based price tracking to identify the cheapest stations in your immediate area, since West Coast prices can vary by 15–30 cents between nearby locations.

Price Outlook for West Coast (PADD 5)

West Coast prices are likely to remain elevated through August as summer driving season peaks, though moderating crude prices and typical late-summer refinery maintenance could provide modest relief by mid-August. Watch for any refinery outages or supply announcements, as the region's tight refining capacity means even small disruptions can push prices up quickly.
