Does Gas Mileage Get Worse in the Winter?
Gas mileage plays a significant role in your driving experience but can change based on the weather. Many drivers notice that their fuel efficiency drops when temperatures get colder. But why does gas mileage get worse in the winter? Read on to discover why fuel efficiency declines in winter and what you can do to improve it. Certified Autoplex in Dallas, TX, can help you find the right car for your needs if you’re looking for a fuel-efficient used vehicle.
Why Does Cold Weather Reduce Fuel Efficiency?
Winter weather affects your car’s gas mileage in several ways. When temperatures drop, your engine takes longer to warm up. A cold engine runs less efficiently, burning more fuel in the process. Tire pressure also decreases in cold weather, creating more rolling resistance. Underinflated tires require more effort to move, reducing your vehicle’s fuel efficiency. Furthermore, winter-grade gasoline contains different additives that make it burn differently. While it helps your car start in cold temperatures, it slightly reduces your miles per gallon. Additionally, winter driving conditions often mean using energy-draining accessories like the heater, defroster, and heated seats. Plus, idling your car to warm it up before driving wastes fuel, further impacting gas mileage.
How-To: Maximize Your Vehicle’s Fuel Economy
How to Improve Gas Mileage in Winter?

- Although cold weather naturally reduces fuel efficiency, simple ways exist to improve it. One easy fix is to keep your tires properly inflated. Another is to check your tire pressure regularly, as cold temperatures cause pressure to drop. Well-inflated tires roll more smoothly and improve fuel economy.
- Another tip is to avoid excessive idling. Warming up your car for long periods wastes gas. Instead, drive gently for the first few minutes to let the engine warm up naturally. Additionally, removing excess weight from your vehicle can help. Snow and ice buildup and extra cargo make your car work harder, consuming more fuel.
- Planning your trips wisely also makes a difference. Short trips use more fuel because the engine doesn’t get a chance to reach optimal efficiency. Combining errands into one longer trip can improve gas mileage during winter.
