If you are driving on US2 and headed West and your looking for fuel, do not buy fuel in Manistique if you can go another 50 miles West to Rapid River or Escanaba. You will find fuel prices in Rapid River and Escanaba some 10¢ to 20¢ cheaper per gallon. The Admiral gas station is usually one of the cheapest in Escanaba. Manistique has Citgo and Shell gas stations that work together to keep prices high. No competition between these two.
One of cheapest places to buy fuel in the Upper Peninsula is Baraga/L'Anse area up near Houghton going toward Copper Harbor.
