Why Does Car Fuel Consumption Increase in Winter?

[VonKaleb]

Here is an analysis of the reasons for higher car fuel consumption in winter: 1. Due to lower temperatures: In winter, the low temperatures cause the engine to maintain higher RPMs after a cold start. If the driving distance is short, the engine may not reach its optimal operating temperature before reaching the destination. Repeatedly keeping the engine at high RPMs can lead to increased fuel consumption. 2. Operational issues: If the heater is not turned off before shutting down the car the previous day, the heater will start along with the engine the next day, causing a loss of some engine heat. Sometimes, turning on the AC (compressor) at the same time adds extra load to the engine. Prolonged idling to warm up the engine not only increases fuel consumption but also leads to more carbon deposits in the engine.
