Do Cars Consume More Fuel in Winter Than in Summer?

Cars consume more fuel in winter than in summer, and the specific reasons are as follows: 1. An engine's optimal working condition requires a certain temperature, generally around 90 degrees Celsius. Only when the engine is in good working condition will fuel consumption be normal. However, outdoor temperatures in winter are relatively low, and after starting, the engine needs a longer running time to reach its optimal working state, leading to increased fuel consumption compared to other seasons. 2. The operation of a car depends on the combustion of gasoline, which inevitably contains some impurities. Over time, these impurities can accumulate on the engine's surface, forming carbon deposits and sludge. This not only damages the engine but can also cause difficulties in starting, high idle speed, excessive exhaust emissions, and more importantly, increases the car's fuel consumption.
Driving in winter does consume more fuel than in summer, as I've deeply realized from over a decade of driving experience. When temperatures are low, the engine is harder to start, and after starting, it requires a longer warm-up period to operate efficiently. During this time, incomplete combustion leads to higher fuel consumption, averaging an increase of over 10%. Although using the heater for warmth is essentially recycling waste heat, the fan and other components consume some electricity, slightly raising fuel consumption. Cold air is denser, increasing wind resistance at high speeds, and tires become harder, adding to rolling resistance. It's advisable to warm up the car for two to three minutes in the morning before driving, check that tire pressure isn't too low to reduce friction, and avoid frequent short trips to save on fuel costs bit by bit. Using these methods long-term has helped me control rising fuel expenses and prevent unexpected damage.
