When do Winter Gas Prices Start?

Winter gas prices start around September 15th, when gas stations switch from the more expensive summer blend to the cheaper winter blend. The switch is driven by government regulations and the fact that winter gasoline is less expensive to produce because it contains more butane, which is cheaper and helps engines start in cold weather. September 15th: This is the typical start date for the switch to winter-blend gasoline in mainland North America, following EPA regulations. Price drop: You will generally see lower gas prices shortly after this date as stations use the cheaper winter fuel. Cheaper blend: Winter gasoline is cheaper to produce than summer-blend, which has higher-cost additives to reduce evaporation and smog during warmer months. Butane's role: Winter gas contains more butane, an inexpensive component that helps a vehicle's engine ignite and start in colder temperatures.
