Finding cheap gas in Algonac (48001)
Algonac is a river town on the St. Clair, about 40 miles northeast of Detroit, and it wears its nautical history proudly as the birthplace of Chris-Craft boats. Together with neighboring Clay Township and Harsens Island, reachable only by ferry, it sits at the southern end of Michigan's Thumbcoast within one of the largest freshwater deltas in North America.
This is a seasonal place, and that drives fuel demand. Summer brings boaters, weekenders, and ferry traffic heading to Harsens Island, which puts pressure on the limited number of stations along the main drag through town. In the warm months the marina-adjacent corners can run firm because the crowd is captive and not price-shopping.
Michigan's gas tax climbed to 52.4 cents a gallon at the start of 2026, which keeps a high floor under every pump in the state. With only a handful of stations in Algonac itself, locals often do their serious fills on trips inland toward the larger markets, saving the in-town pumps for when they are running low rather than for routine top-offs.

How to save more on gas in Algonac
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.
