Finding cheap gas in Billings (59101)
Billings sits right on top of one of the Rocky Mountain region's busiest refining clusters. Three of Montana's four oil refineries operate in Yellowstone County, including the big Par Pacific and Phillips 66 plants along the Yellowstone River, and that local production makes Billings a hub for fuel distributed across Montana and into neighboring states.
This central ZIP covers downtown and the older valley neighborhoods carved by the river, with King Avenue, Grand Avenue, and the Interstate 90 ramps carrying the heaviest traffic. The high-volume stations near those corridors and the warehouse and grocery fuel centers tend to turn product over fastest and price the sharpest.
Having refineries in the backyard does not guarantee bottom-dollar gas, since pump prices still track the regional market, but it does keep Billings well supplied. Comparing the Grand and King Avenue stations against the ones near the I-90 interchanges is the practical way to find the low number.

How to save more on gas in Billings
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 Montana
Montana refines fuel locally at three in-state refineries: the Phillips 66 Billings, Calumet Great Falls, and Cenex Laurel facilities, with combined capacity around 200,000 barrels per day. The state is essentially self-sufficient most of the year. The state gas tax is around 33 cents per gallon. Billings, Missoula, and Great Falls all see relatively competitive pricing. Costco, Sam's Club, Town Pump, and Albertsons grocery fuel are the dependable value picks across Billings, Missoula, and Great Falls. Western Montana near the Idaho border occasionally tracks Idaho pricing during refinery maintenance windows, while eastern Montana near North Dakota benefits from Bakken-region pipeline access.
