Why does Vision x3 waste oil?

The following are the specific reasons for the fuel consumption of Vision x3: 1. Affected by temperature: it leads to fluctuation of fuel consumption, which will increase when the temperature is low in winter. 2. The vehicle has not been maintained for a long time: unclean oil and air filter elements will also lead to increased fuel consumption. Dirty oil leads to poor lubrication, which leads to increased resistance of all moving parts of the engine. More energy is needed to overcome resistance and fuel consumption will increase. 3. Too much carbon deposit on the vehicle: too much carbon deposit on the throttle, injector, air intake and piston top will lead to incomplete combustion and increase fuel consumption.
