Fuel consumption after changing the automatic transmission oil can potentially change, mainly in the following situations:
Reduced fuel consumption:
* More efficient gear shifting: New gear oil provides better lubrication and reduces friction in automatic transmission components, which can improve smooth shifting and reduce energy loss.
* Reduce Slip: Fresh automatic transmission oil can help reduce transmission slip that occurs between the friction plates. Less slip means less energy loss and therefore higher efficiency.
* Restoring Oil Pressure: Changing the automatic transmission oil can restore optimal oil pressure to the system, ensuring proper lubrication and operation of all components. This can lead to improved performance and reduced energy loss.
Increased fuel consumption:
* Incorrect oil: If the wrong transmission oil is used for the automatic transmission, this can lead to problems with gear shifting, slipping or reduced oil pressure. All this can lead to increased energy losses and, consequently, increased fuel consumption.
* Automatic transmission malfunctions: In some cases, changing the automatic transmission oil can reveal or aggravate existing problems in the transmission. These malfunctions can prevent the automatic transmission from operating efficiently and lead to increased fuel consumption.
Generally:
In most cases, changing automatic transmission oil leads to reduced fuel consumption due to improved transmission performance. However, it is difficult to predict the exact amount of change in fuel consumption, since it depends on the specific vehicle, the condition of the automatic transmission and the type of oil used.
