Frequently asked questions
Are Costco gas prices going up or down right now?
It varies week to week and by region. This page recaps the direction over the past month for regular, premium, and diesel as a national average, then ranks the states and individual warehouses that moved the most. The snapshot box at the top names the grade with the biggest move right now.
How often do Costco gas prices change?
Costco adjusts pump prices frequently — often more than once a week at busy warehouses. We refresh this page daily from a rolling 30-day price history, so it shows the recent trend rather than a single day’s number.
Where is Costco gas cheapest right now?
Prices vary widely by state because of taxes and local supply — low-tax states tend to be cheapest, while the West Coast and Northeast run highest. Our state leaderboard ranks every state by its current average.
Why did Costco gas prices change recently?
Costco buys finished fuel from the same regional refineries that supply other brands, so its prices track the wholesale market — crude-oil swings, refinery maintenance, seasonal blend changes, and state taxes all feed through. Costco usually passes those moves on quickly while holding a below-market margin.
How do you measure the “biggest movers”?
For each warehouse we compare the latest price against roughly a month earlier, using the same 30-day history that powers our price charts, then rank states and stations by that change. Stations without a comparable earlier reading are left out, and tiny moves of under about a cent are treated as flat.
Costco gas price trends in other countries
Prices move differently in each market. See the latest recap for Canada, the UK, Australia, and Mexico.
