Why does my Toyota Corolla's gas mileage decrease during the winter months?

I've noticed that my gas mileage has significantly decreased during the winter months, even though I haven't changed my driving habits. Is there something wrong with my car or is this a common issue with Toyota Corollas?

It's completely normal for your gas mileage to decrease during the winter months. The cold weather causes your engine to work harder and burn more fuel to maintain the same level of performance.

To improve your gas mileage during winter, make sure you're using the recommended oil viscosity for cold weather and keep your tires properly inflated. Also, try to limit idling and use your car's heater efficiently.

I have a Toyota Corolla too and I've noticed the same issue. One trick that has helped me is to schedule regular maintenance check-ups, especially before the winter season. A well-maintained car will have better fuel efficiency.
