What are the reasons for the sudden increase in fuel consumption of Volkswagen Bora?
2 Answers
Volkswagen Bora's sudden increase in fuel consumption may be caused by engine carbon deposits, spark plug failure, abnormal tire pressure, and other reasons. Engine carbon deposits: During long-term operation of the vehicle, gasoline inevitably produces carbon deposits and sludge during combustion. If these sludge and carbon deposits are not cleaned in time, they will lead to an increase in car fuel consumption. It is necessary to clean the engine carbon deposits. Spark plug failure: The function of the car spark plug is to use high-voltage electricity to generate sparks to ignite the mixed gas. If damaged, it will reduce the ignition energy, causing uneven combustion of the mixed gas, which will lead to slower vehicle acceleration and increased fuel consumption. Replace the spark plug or clean the carbon deposits on the spark plug. Abnormal tire pressure: Abnormal tire pressure can also affect the car's fuel consumption. When the tire pressure is too low or the tire tread is severely worn, the contact area between the tire and the road surface increases, friction increases, rolling resistance increases, and fuel consumption naturally rises. Check the tire pressure and replenish it in time.
My Volkswagen Bora has been experiencing a sudden surge in fuel consumption lately, which is really annoying. I remember one time when the fuel consumption suddenly increased, so I checked the tire pressure and found that the front tires were underinflated. This increased rolling resistance, making the car harder to drive and naturally consuming more fuel. Then I checked the air filter, which was clogged with dust, restricting airflow and causing incomplete fuel combustion in the engine. Additionally, the spark plugs were worn out, leading to unstable ignition and further increasing fuel consumption. I suggest starting with these simple checks: measure and maintain tire pressure at around 2.5, replace the air filter regularly, and inspect the condition of the spark plugs. Also, pay attention to driving habits—accelerate gently and avoid sudden braking. These small adjustments can save you a lot of money and time.
