Why does Mercedes-Benz glc300l waste engine oil when idling?

The fuel consumption of Mercedes-Benz glc300l at idle state is due to weather factors or too much carbon deposit. The high fuel consumption may be caused by the weather, that is, it is hot in summer, and the fuel consumption will be high when the air conditioner is turned on. Moreover, in winter, the engine has poor combustion efficiency and high fuel consumption. Another situation is that the engine has too much carbon deposit, which leads to dirty throttle, reduced atomization effect of fuel nozzle and increased fuel consumption. Finally, it may have something to do with your driving habits.

Causes of high fuel consumption

No matter which gear, keep the engine speed at around 2200-2500. The speed is too low, the car can't move, the fuel consumption is not too high, and it also hurts the engine. Excessive speed will increase ineffective fuel consumption, and will also hurt the engine. The level of fuel consumption is related to the unified road conditions and everyone's driving habits. Without an agreed standard, the fuel consumption in winter will indeed be slightly higher than that in spring and autumn, because the temperature in winter is low and the ignition point of gasoline is low, and the idle time in winter is slightly longer than that in summer.
