What Are the Reasons for High Fuel Consumption in Cars and Their Solutions?

[ClaraFitz]

Detailed reasons for high fuel consumption in cars and their solutions are as follows: 1. Insufficient tire pressure and tire wear: Low or insufficient tire pressure increases friction between the tires and the ground, leading to greater resistance and higher fuel consumption. Severe tire wear often results in slipping, which also increases fuel consumption. Solution: Replace the tires. 2. Poor-quality gasoline: Low-quality gasoline leads to more carbon deposits, which roughen the intake pipe walls, affecting the intake efficiency and the quality of the air-fuel mixture, causing a sharp rise in fuel consumption. Solution: Use higher-quality gasoline. 3. Prolonged use of the oxygen sensor: The oxygen sensor, a ceramic component located on the engine's exhaust pipe, detects and controls the oxygen-to-fuel ratio. Extended use can prevent the electronic fuel injection system's computer from receiving accurate oxygen concentration information from the exhaust pipe, resulting in a higher concentration of the air-fuel mixture in the engine and increased fuel consumption. Solution: Regularly inspect the oxygen sensor's condition and replace it promptly.
