Finding cheap gas in Niles (49120)
Niles calls itself the City of Four Flags for the four nations that once held the old fort here, and it sits right on the Michigan-Indiana line, just up US-31 from South Bend. The US-12 and US-31 crossroads make it a small gateway between the South Bend manufacturing belt to the south and the I-94 corridor to the north.
That state line matters at the pump. Michigan and Indiana tax fuel differently, and the gap has been unusually volatile lately, with Indiana suspending parts of its gas tax in 2026, so the cross-border math shifts month to month. Drivers near the line have long paid attention to which side is cheaper on any given week, and it is worth a quick check before you fill if your day takes you across into Indiana anyway.
On the Michigan side, the statewide tax of 52.4 cents a gallon sets the floor. The stations along US-31 and the busier Niles commercial stretches see the most traffic and the most competition, so they are generally your steadier bet over the quieter corners away from the main routes.

How to save more on gas in Niles
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 Michigan
Michigan's gas tax is around 31 cents per gallon, with a 6 percent sales tax also applied to fuel sales (one of the few states that double-taxes gas this way). The state pulls supply from refineries in Detroit and across the Ohio and Indiana border, with prices in the Upper Peninsula often running 15 to 30 cents higher than the Lower Peninsula due to longer supply lines from Wisconsin or Marathon's Detroit refinery. Speedway, Costco, Sam's Club, and Meijer Gas are the consistent best prices, especially in the Detroit, Grand Rapids, and Lansing metros.
