Today's North Dakota Gas Prices
Today's regular unleaded price in North Dakota is $$2.97 per gallon, placing it below ($1.02) the national average. North Dakota's Plains regional market conditions — including refinery proximity and pipeline access — play a decisive role in pricing.
In North Dakota, as in most US states, Monday and Tuesday tend to show the lowest weekly prices. Prices rise Thursday through Sunday as weekend demand increases. Filling up Tuesday afternoon typically captures the weekly low.
North Dakota charges 23 cents per gallon in state fuel taxes. The national average is around 30 cents per gallon. North Dakota's tax places it among the mid-range states nationally for fuel taxation.
North Dakota gas stations offer regular (87 octane) at $$2.97, mid-grade (89 octane) at approximately $$3.43, premium (91-93 octane) at $$3.71, and diesel at $$4.02 per gallon. Most stations also offer E85 ethanol blend where flex-fuel vehicles are common.
Many states require reformulated gasoline (RFG) or special summer blends to meet EPA air quality standards during warmer months. These blends reduce evaporative emissions but cost 5-15 cents more per gallon to produce.
Costco consistently offers the cheapest gas in any North Dakota market where it operates — typically 15-20 cents below local street prices. Circle K, Speedway, and QuikTrip (where available) also routinely undercut the market average. Premium brands like Shell, Chevron, and BP typically price above the local average.
