All prices in USD per gallon.
30-day U.S. average diesel price trend
Costco sells diesel at select warehouses, not chain-wide. Right now 67 of the 600 Costco gas stations we track in the United States post a live diesel price. Whether a warehouse has a diesel lane comes down to fuel-centre size and local demand, so the only reliable check is the station page itself. Like Costco's other fuels, diesel is sold at a thin margin to pull members onto the site, and it usually sits below nearby forecourts.
Members only. The pump reads your membership card before it dispenses, diesel included. Payment rules differ by country; see the Costco U.S. fuel payment methods guide.
Prices change daily. The figures here refresh daily from public sources and differ from one station to the next. For every fuel at every warehouse, see the U.S. Costco fuel prices page. Always check the pump display before you fill.
