Comparing Montana's price to the U.S. average shows whether local drivers pay more or less than the nation as a whole. State fuel taxes, regional refining capacity, and supply logistics are the main drivers of that gap.
Why Do Gas Prices Move?
Gasoline prices follow crude oil markets, refinery output, seasonal demand, and state taxes. Geopolitical events, hurricanes affecting Gulf Coast refineries, and OPEC production decisions can move prices sharply within weeks.
