How Many Kilometers Should Car Gear Oil Be Replaced?
1 Answers
Gear oil should be replaced every 60,000 kilometers. The following points should be noted during oil change: 1. Use gear oil properly to extend its service life. 2. If using single-grade oil, switch to different viscosity grades during seasonal maintenance. If the drained old oil has not reached the replacement interval, it can be reused during the next oil change. 3. Store old oil properly, strictly preventing contamination from moisture, mechanical impurities, and waste oil. Here is some extended information about car gear oil: 1. Car gear oil usually refers to transmission oil and rear axle lubricating oil. These transmission mechanisms have many gear components and operate under high surface pressure. Therefore, they require functions such as lubrication, cooling, heat dissipation, and corrosion prevention. 2. If the oil viscosity is too high, it can cause overheating of friction surfaces and unnecessary power loss. 3. If the viscosity is too low, centrifugal force may cause the oil to be thrown off the gear surfaces, leading to oil seal leaks. This can result in insufficient lubrication on gear surfaces, increasing wear and even causing sintering. Therefore, choosing the appropriate viscosity is crucial.
