If the transmission oil is not replaced within a certain cycle, the consequences will become increasingly serious, with multiple hazards. Advantages of transmission oil: Transmission oil plays roles in cleaning, lubricating, cooling, and sealing for the transmission. Due to the specific operating environment inside the transmission, the quality of the oil has a certain shelf life. The performance of the oil will decline, generating more impurities, which leads to accelerated wear of transmission components, earlier occurrence of failures, or a higher failure rate. Notes: 1. Manual transmission oil can generally be replaced at 60,000 kilometers; 2. Whether it is manual transmission oil or automatic transmission oil, both need to be inspected and replaced within a certain cycle.

What Causes Excessive Fuel Metering Unit Flow?

Excessive fuel metering unit flow indicates a malfunction in the fuel metering unit, leading to increased fuel consumption or reduced power. If the fuel injection quantity of the metering unit is higher than the calibrated value, the amount of fuel entering the cylinder each time will increase, resulting in higher fuel consumption and a significant drop in vehicle power. In severe cases, it may even prevent ignition. Additional Information: Symptoms of a faulty metering unit: The engine warning light on the vehicle dashboard illuminates, and the vehicle fails to start. When the fuel metering unit is damaged, the vehicle will automatically shut off the fuel injector to prevent damage caused by excessive internal pressure. The fuel metering unit is typically installed near the high-pressure fuel pump and primarily functions to control fuel injection quantity and fuel pressure values.
