Finding cheap gas in Hammond (46320)
Hammond's western neighborhoods run right up to the Illinois state line, and that border is the single biggest factor in how gas gets bought here. Indiana taxes gasoline at roughly 29 cents a gallon while Illinois sits near 66, so the price gap is stark the moment you cross over.
The commercial stretches along Indianapolis Boulevard and the routes feeding the Indiana Toll Road draw a constant flow of Chicago-area drivers who time their fill-ups for the Indiana side. Stations positioned near the line and the toll-road ramps know exactly who their customers are and stay competitive for that cross-border business.
For residents, the payoff is year-round cheap fuel without driving anywhere. The catch is that the busiest border stations sometimes nudge prices up because demand is so reliable, so it can pay to check a station a little deeper into Hammond rather than the very first one past the state line. Whiting and Munster nearby add still more options.

How to save more on gas in Hammond
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 Indiana
Indiana hosts the BP Whiting refinery on the Lake Michigan shore, which is the largest refinery in the Midwest at roughly 440,000 barrels per day and serves as the dominant supply source for Chicago, Northwest Indiana, and large parts of the Midwest. The state gas tax is around 33 cents per gallon when sales tax is layered on, slightly above the Midwest average. Costco, Sam's Club, Speedway (now part of 7-Eleven), and Murphy USA at Walmart locations are the most reliable for value across Indianapolis, Fort Wayne, and Evansville. Gary and Hammond often see the lowest pump prices statewide thanks to direct Whiting refinery supply.
