Why is my mpg lower in winter?
Why is winter fuel economy lower? Cold weather affects your vehicle in more ways than you might expect: Engine and transmission friction increases in cold temperatures due to cold engine oil and other drive-line fluids. It takes longer for your engine to reach its most fuel-efficient temperature.
How does cold weather affect your gas mileage?
Cold weather and winter driving conditions can reduce your fuel economy significantly. Fuel economy tests show that, in city driving, a conventional gasoline car’s gas mileage is roughly 15% lower at 20°F than it would be at 77°F. It can drop as much as 24% for short (3- to 4-mile) trips. The effect on hybrids is typically greater.
How to improve fuel economy in cold weather?
Minimize idling your car to warm it up. Most manufacturers recommend driving off gently after about 30 seconds. The engine will warm up faster being driven, which will allow the heat to turn on sooner, decrease your fuel costs, and reduce emissions. Don’t use seat warmers or defrosters more than necessary. Check your tire pressure regularly.
Is it true that under inflated tires lower gas mileage?
One fact worth noting comes directly from the U.S. Department of Energy, which has proven that under-inflated tires have a negative effect on your fuel economy. The department states that for every 1-psi drop in pressure, you can expect your gas mileage to lower by 0.4 percent. And, that is not a myth.
Can you increase air pressure to increase gas mileage?
According to Mark Cherveny, manager of global regulations, standards and compliance for Goodyear Tire & Rubber Company, “You can increase fuel economy by increasing air pressure, but the improvement would be marginal at best and Goodyear definitely does not recommend doing it.”

What’s the average gas mileage for a car?
Take advantage of current interest rates to lock in savings today. Despite the advancement in hybrid technologies and modern fuel saving systems, most cars still have low gas mileage. The average is still around 23 mpg in the city. Even worse, average gas mileage is in the teens for most SUVs and minivans.
