Colorado sits at a landlocked crossroads with no direct pipeline access to coastal refineries. All fuel arrives via pipeline from the Gulf Coast or Wyoming/Montana refineries. Denver and the Front Range require a special oxygenated blend in winter months, which can raise prices seasonally. Mountain communities pay more due to transport distance.
