How to save more on gas in Duluth
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in Minnesota
Minnesota refines roughly half its consumed gasoline locally at the Flint Hills Resources Pine Bend refinery (a 370,000 barrel-per-day facility near Rosemount) and the Marathon St. Paul Park refinery. The state gas tax is around 29 cents per gallon. Minneapolis, Saint Paul, Duluth, and Rochester all see competitive pricing, with Costco, Sam's Club, Holiday Stationstores (a Minnesota chain owned by Couche-Tard), and Kwik Trip competing on value across these metros. Duluth and Rochester run slightly higher than the Twin Cities due to longer trucking distances. The state requires E10 ethanol blends year-round, and the Twin Cities also require summer reformulated gasoline that adds production cost from June through September.
