Because fuel prices fluctuate daily based on market conditions, we don't list exact per-gallon figures on this page.

Oregon currently has 2 Costco locations with diesel fuel — in Central Point and Portland. While that number is modest, it reflects Costco's ongoing expansion of diesel availability across the Pacific Northwest. If you're traveling through southern Oregon along I-5, the Central Point location near Medford is a convenient stop. For Portland-area drivers, the NE 138th Ave warehouse offers diesel alongside standard gasoline.
Costco diesel is ultra-low sulfur diesel (ULSD) with added detergents to keep your engine clean.

Costco gas stations in Oregon typically operate from 6:00 AM to 10:00 PM on weekdays, with slightly reduced hours on weekends. A valid Costco membership is required to purchase fuel — this is enforced at the pump by the membership card reader. Executive members earn 2% cashback on gas purchases (subject to an annual cap), which can make the membership pay for itself if you fuel up regularly.
