Finding cheap gas in Port Huron (48060)
The Blue Water Bridge defines Port Huron. Soaring over the St. Clair River to Sarnia, Ontario, it is the second-busiest commercial truck crossing on the entire Canada-US border, and Interstates 94 and 69 both converge on it. That funnel of freight and travelers is the backdrop to how gas gets priced near the bridge approaches.
A common assumption trips people up here: filling up across the bridge in Canada is not the bargain it might look like, because Canadian fuel taxes run high and pump prices there, converted to US dollars per gallon, usually come out above what you pay in Michigan. Combined with Michigan's own 52.4-cent fuel tax in 2026, there is no cross-border savings angle for a Port Huron driver.
So the buying happens on the American side. The handful of stations right at the bridge plaza serve truckers and crossing traffic and tend to hold firm, while the corners spread through downtown and the surrounding neighborhoods carry more of the city's day-to-day business and price accordingly. For a quick, fair fill, those interior Port Huron stations are the ones to aim for.

How to save more on gas in Port Huron
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.
