What Are the Reasons for Increased Fuel Consumption?

[CourtneyMarie]

Here are the specific reasons for increased car fuel consumption: 1. Affected by temperature: Fuel consumption fluctuates due to temperature changes. In winter, lower temperatures generally lead to higher fuel consumption. 2. Lack of vehicle maintenance: Dirty engine oil and air filters can also cause increased fuel consumption. Dirty oil leads to poor lubrication, increasing resistance in the engine's moving parts, requiring more energy to overcome the resistance, which raises fuel consumption. 3. Low tire pressure: Insufficient tire pressure increases the contact area between the tires and the road, resulting in greater friction and driving resistance, leading to higher fuel consumption. 4. Excessive carbon buildup: Carbon deposits commonly accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas can cause incomplete combustion, resulting in increased fuel consumption.
