Why has my car’s fuel consumption increased significantly?

发布时间：2022年03月14日 15:29

Many people have noticed that their vehicles—once known for relatively low fuel consumption—suddenly start consuming much more fuel as they drive them. So today, let’s join Qingjie to find out exactly what’s behind this phenomenon! Poor driving habits can significantly increase fuel consumption—for instance, frequent rapid acceleration and braking, as well as constant starting and stopping. Therefore, adopting good driving habits is a crucial factor in keeping fuel consumption under control. Additionally, if a vehicle carries excessively heavy loads, its fuel efficiency will also suffer. Thus, it’s best to minimize the load as much as possible. Insufficient tire pressure: When tire pressure is too low, the contact area between the tires and the road surface increases, leading to excessive friction and greater resistance, which in turn boosts fuel consumption. Moreover, car enthusiasts should also...

　　Many people have noticed that their vehicles, which originally didn't consume much fuel, suddenly start consuming significantly more fuel as they keep driving. So today, let’s join Qingjie Jun to find out exactly what’s causing this!

　　Bad driving habits can lead to higher fuel consumption—for example, frequent rapid acceleration and braking, as well as frequent starting and stopping. Therefore, good driving habits are a crucial factor in preventing fuel consumption from rising. Additionally, if a vehicle carries excessively heavy loads, its fuel efficiency will also decrease; thus, it’s best to minimize the load as much as possible.

　　Insufficient tire pressure—when tire pressure is too low—can increase the contact area between the tires and the road surface, leading to excessive friction and greater rolling resistance, which in turn increases fuel consumption. In addition, drivers should regularly check the degree of tire wear. If the tires are severely worn, they may slip more easily, further boosting fuel consumption.

　　For ignition system failures, pay special attention to the battery and spark plugs. The battery must be replaced regularly; a depleted battery can lead to insufficient starting voltage, causing the starter motor to lack power when turning over the engine, reducing ignition performance, and naturally causing fuel consumption to soar.

　　Choosing the right engine oil is crucial—using the wrong type of oil can significantly affect fuel consumption. The quality of the oil directly impacts fuel efficiency. Prolonged use of low-quality oil can lead to increased carbon buildup, making the walls of the intake manifold rougher and impairing the intake performance and the quality of the air-fuel mixture, thereby causing fuel consumption to rise. Additionally, different seasons, vehicle models, and driving conditions call for different types of engine oil. Vehicle owners should select the appropriate oil based on their vehicle’s maintenance manual as well as their actual driving conditions.

　　If fellow drivers notice a sudden increase in fuel consumption, they can pay close attention to the aspects mentioned above. Also, be sure to perform regular maintenance and keep an eye on any changes your car might show—stay safe on the road every single day!
