How to Tell if a Car is Fuel-Consuming?
2 Answers
Methods to determine if a car is fuel-consuming are as follows: 1. Displacement: Many consumers are aware that vehicles with larger displacements generally have more horsepower, which inevitably leads to higher fuel consumption. 2. Vehicle Weight: Heavier vehicles require the engine to output more power to drive them, naturally resulting in higher fuel consumption. Therefore, lighter vehicles typically have lower fuel consumption. 3. Drag Coefficient: Vehicles encounter some degree of wind resistance while driving, especially at high speeds. Higher wind resistance leads to greater fuel consumption. Thus, vehicles with lower drag coefficients naturally consume less fuel. Information on drag coefficients can be found online before purchasing or by consulting sales advisors on-site. 4. Tire Width: Generally, the diameter of the tires has little impact on fuel consumption, but wider tires increase fuel consumption. This is because wider tires have a larger contact area with the ground, increasing frictional resistance during driving and consequently raising fuel consumption.
I remember when I used to drive an old car, the fuel consumption suddenly increased, mainly judged by daily refueling records. After each full tank, I would record the mileage and the amount of fuel added in a mobile app or a small notebook, and then calculate the fuel consumption per 100 kilometers after about a week of driving. Normally, it should be around 8-10 liters. If it spikes to over 12 liters, it feels off. You also need to consider driving habits, such as frequent hard acceleration or constant traffic jams, which can also increase fuel consumption. Additionally, regularly checking tire pressure is crucial. Low tire pressure increases friction, leading to higher fuel consumption. If the engine sounds louder than before or lacks power during acceleration, it's a sign of increased fuel consumption. It's recommended to calculate it yourself every month to detect issues early and avoid wasting money and damaging the engine.
