What are the reasons for high fuel consumption in old Mark X?

[DeKeegan]

The reasons for increased fuel consumption in old Mark X include insufficient tire pressure and tire wear, severe carbon buildup, and improper driving habits. Below are specific methods to reduce fuel consumption: 1. Lightly press the accelerator: When the car starts at low speed, it is the peak area of fuel consumption. Therefore, lightly pressing the accelerator during startup can prevent excessively high RPM and effectively reduce fuel consumption. 2. Avoid high RPM: Try to avoid unnecessary high RPM as fluctuating engine speeds can significantly consume fuel. 3. Regular maintenance: Regularly change the engine oil and remove carbon deposits. 4. Avoid emergency braking: Anticipate road conditions in advance to avoid emergency braking, which not only improves driving safety but also saves fuel. For example, slow down gradually before traffic lights and utilize inertia to glide.
