What should I do if the fuel consumption of Tiida increases?

The maintenance of the above vehicles is recommended to be evaluated once a week according to the fuel consumption display value. If the fuel injector is disassembled for cleaning, there should be no problem. If it is disassembly, I suggest you check the engine data flow to see if the engine works within the standard range. Secondly, for the phenomenon of lubricating oil, if the number of kilometers traveled in a year is more, the remaining engine oil can be recovered, and if it is less, the above operation is not recommended according to the nature of lubricating oil. There should be no problem with fuel quality abroad, but cars in Beijing are equipped with obd diagnosis system, which requires higher combustion. I suggest you add a higher grade fuel.
