How to save more on gas in Sioux Falls
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 South Dakota
South Dakota draws pipeline supply from refineries in Wyoming (Cheyenne, Sinclair), North Dakota (Mandan), and Minnesota (Pine Bend), with no significant in-state refining. The state gas tax is around 30 cents per gallon. Sioux Falls, Rapid City, and Aberdeen see fairly competitive pricing within the state, with Costco (in Sioux Falls), Sam's Club, Casey's General Store, and Coborn's grocery fuel leading on value. Western South Dakota near the Wyoming border occasionally runs 5 to 10 cents below eastern South Dakota due to shorter pipeline distances from Wyoming refineries. The Black Hills tourist region sees moderate seasonal price increases during summer.
