The quality and quantity of transmission fluid are key factors in ensuring the smooth operation of a transmission. If the transmission fluid is low or of poor quality, it can lead to a decrease in transmission efficiency, which in turn increases the vehicle's fuel consumption. This happens because insufficient or excessive fluid can increase gear rotation resistance, affecting transmission efficiency and ultimately raising fuel consumption.
In addition, a noticeable increase in fuel consumption after changing the transmission fluid could be due to several factors. One is the use of low-quality transmission fluid, which typically has higher viscosity and poor oxidation resistance, causing the transmission to work under greater load, thus increasing fuel consumption. Moreover, carbon buildup in the throttle body can also affect fuel consumption. Severe carbon deposits can lead to unstable airflow, which disrupts fuel consumption control.
Therefore, to keep fuel consumption at a reasonable level, it is important not only to maintain good driving habits but also to manage the transmission and transmission fluid properly. Maintaining the correct level and quality of transmission fluid, and replacing the transmission filter in a timely manner are all crucial steps in ensuring a healthy transmission and stable fuel consumption.
