Idaho is well-positioned for Costco diesel drivers, with 2 locations offering diesel fuel. Both stations dispense premium ultra-low sulfur diesel that meets or exceeds all manufacturer specifications. Idaho's strong truck and agricultural communities make diesel a popular fuel choice, and Costco's pricing typically beats name-brand diesel stations by 20 to 40 cents per gallon.
When comparing Costco diesel vs. Shell diesel, the key differentiator is cost savings rather than fuel quality — both meet stringent ULSD standards. Idaho's cold winters can be tough on diesel engines, so using quality cold-weather diesel additives is recommended to prevent fuel gelling during sub-zero temperatures in the Treasure Valley and mountain regions.
Costco gas stations in Idaho typically operate from 6:00 AM to 10:00 PM on weekdays, with weekend hours usually 6:00 AM to 9:00 PM.

Executive members earn 2% cashback on gas (up to $1,000 annually), which is valuable for Idaho drivers with long rural commutes.
