Why Has the Car's Fuel Consumption Suddenly Increased?

[BriannaDella]

The main reasons for a sudden increase in car fuel consumption are: 1. Engine carbon deposits: During long-term operation, gasoline inevitably produces carbon deposits and sludge during combustion. If these deposits and sludge are not cleaned in time, they will lead to increased fuel consumption. 2. Spark plug failure: The function of car spark plugs is to generate an electric spark with high voltage to ignite the air-fuel mixture. If damaged, the ignition energy decreases, causing uneven combustion of the mixture, which results in slower acceleration and increased fuel consumption. At this point, it is necessary to promptly inspect and replace the spark plugs. 3. Abnormal tire pressure: Improper tire pressure can also affect the car's fuel consumption. When the tire pressure is too low or the tread is severely worn, the contact area between the tire and the road surface increases, leading to greater friction, higher rolling resistance, and naturally higher fuel consumption. Of course, conversely, excessively high tire pressure can have a certain fuel-saving effect, but this will reduce the ride comfort and pose a risk of tire blowouts. Therefore, drivers should also pay attention to whether the tire pressure is normal while driving.
