How does Dongfeng Citroen wash the throttle?

On the one hand, air filtration will also affect the acceleration of the engine. Replace the air filter.

If there is too much carbon deposit in the intake system, up to 20000KM, a large amount of carbon deposit will appear, which will also have a certain impact on fuel consumption, but it will not be too great. Use the disassembly-free cleaning scheme, or disassemble the intake pipe to clean the carbon deposit.

Dirty injector will lead to the needle valve not being closed tightly, which will make the injector slow and leak oil. Clean the fuel injector with efficient cleaning agent without disassembly.

The fuel system pressure is higher than the standard, which can reflect the trend of increasing fuel consumption. Use the fuel pressure gauge to detect the system pressure. If it is not normal, fix it.

The viscosity of manual transmission oil is too thick, which increases the running resistance of the engine and naturally leads to high fuel consumption. Gear oil GL-4 or synthetic gear oil GL-5,75 with proper viscosity is the best.
