Have you noticed that you need to refuel more often during the colder months? Even if you follow the same routes and maintain your usual driving habits, your car may use more fuel when winter arrives.
Low temperatures affect several vehicle components, particularly during the first few miles of a journey. Understanding why this happens and making small changes to your driving habits can help improve fuel efficiency.
Your engine takes longer to reach its ideal operating temperature
When you start your car in cold weather, the engine has not yet reached its optimal operating temperature. During the first few minutes, certain components operate less efficiently, and the engine management system may need to use a richer fuel mixture.
This is why short journeys are particularly affected. If you mainly use your vehicle for commuting around town, you may notice higher fuel consumption during winter.
According to the US Department of Energy, cold temperatures can significantly reduce the fuel efficiency of petrol-powered vehicles, especially in urban driving conditions.
Tyre pressure also affects fuel consumption
As temperatures drop, tyre pressure can decrease. Driving with underinflated tyres increases rolling resistance, meaning your vehicle requires more energy to keep moving.
Checking tyre pressure regularly is therefore essential, not only for fuel efficiency but also for road safety.
The Spanish Directorate-General for Traffic (DGT) highlights the importance of proper tyre maintenance and efficient driving techniques to reduce fuel consumption.
Heating and electrical systems
During winter, drivers use features such as heated rear windows, heated mirrors and ventilation fans more frequently.
These systems require energy to operate, which can lead to a slight increase in fuel consumption. Cold air is also denser, increasing aerodynamic drag, particularly when driving at higher speeds.
However, saving fuel should never come at the expense of safety. Always ensure your windows are clear and visibility is adequate before driving.
How can you reduce fuel consumption in winter?
Smooth driving is one of the most effective ways to improve efficiency. Avoiding sudden acceleration and harsh braking can help you use less fuel while making journeys more comfortable.
Regular vehicle maintenance, correct tyre pressure and careful journey planning can also make a difference.
Another common mistake is leaving the engine idling for several minutes before setting off. In modern vehicles, it is generally more efficient to start driving gently rather than waiting for the engine to warm up while stationary, following the manufacturer’s instructions.
