About gas prices in Idaho
Idaho is part of PADD 4 (Rocky Mountain) and pulls fuel from refineries in Salt Lake City and Billings, with prices that closely track Wyoming and Montana rather than the West Coast. The state gas tax is around 32 cents per gallon. Boise sees the lowest pricing in the state, with Costco, Sam's Club, Stinker Stores, and Maverik competing aggressively. North Idaho (Coeur d'Alene, Sandpoint) typically prices closer to Spokane Washington pricing due to shared distribution networks. Eastern Idaho near the Wyoming and Utah borders sometimes runs 5 to 15 cents below the Treasure Valley because of refinery proximity and lower local taxes.
