Drivers in Bismarck, North Dakota are now paying on average $2.956 per gallon for regular unleaded gasoline as of mid-September 2025 — a drop of about $0.28 compared to a year ago. Over the past week the price has held relatively steady, with only slight fluctuations.
The state average for regular unleaded gasoline in North Dakota stands at about $2.930 per gallon, slightly lower than Bismarck’s average.
Prices one month ago in Bismarck were roughly $3.012 per gallon, making the current rate a modest drop month-to-month.
Compared to September 2024, prices in Bismarck are down from approximately $3.246 per gallon to today’s $2.956, marking a year-over-year decrease of nearly 8.6%.
These trends align with broader state and national movements: North Dakota as a whole is seeing gas prices decline year-over-year, consistent with the U.S. average slightly lower than this time last year.
Many Bismarck commuters have seen relief at the pump, especially those driving daily to work, school, or for errands. Even small drops add up when gas is purchased frequently.
Local businesses reliant on transportation (e.g., delivery, freight) are gaining modest cost relief, though concerns remain about future price bumps if oil supply, seasonal demand, or regulatory changes shift.
Some gas stations in Bismarck are offering regular and mid-grade fuel at prices slightly below the city average, giving consumers where to shop around.
Gas station owner Ali Khan, from a Mobil station off North 19th, commented: “Margins are thin, but the current trend is helping us keep regular prices under $3.00. We watch wholesale oil and state taxes closely — any change there echoes here fast.”
For drivers in Bismarck, the current fall in gas prices is a welcome break from the highs of the past year. While rates are down significantly compared to 12 months ago, small week-to-week gains suggest volatility remains. Going forward, watchers should monitor crude oil markets, pipeline logistics, and state fuel taxes — all of which could quickly influence local pump prices. Budgeting for fuel should assume mild fluctuations, but unless a major supply disruption occurs, prices may stay near current levels through autumn.
