The fuel consumption of car attendants increased after using gold liquid.

1. First of all, the engine has too much carbon deposit, which leads to an increase in fuel consumption. In this case, it is easy to accumulate too much carbon after driving 30 thousand kilometers. It can clean the carbon deposit on the accelerator and engine of the vehicle.

2. Secondly, due to the failure of the ignition system, the fuel consumption increases. This situation is the phenomenon that the spark plug aging gap is too large or the ignition coil is damaged, so it is necessary to check the spark plug gap in time. If the gap is too large, it needs to be replaced in time, and then decoded by computer to check whether there is any problem with the ignition coil. If there is any problem, it needs to be replaced in time.

3. Finally, the fuel consumption of sensors or oil circuits related to the engine is blocked. In this case, it is necessary to replace the gasoline filter in time, then clean the nozzle, read some fault codes of the vehicle engine system with a computer, and focus on checking whether the intake pressure sensor and oxygen sensor are faulty. If there is any fault, the damaged parts need to be replaced accordingly.
