How Many Kilometers Should Gear Oil Be Changed?

[LaMary]

Gear oil should be changed every 60,000 kilometers. Here is an introduction to the relevant content: 1. Function: It can effectively improve the efficiency of engine power transmission through gears. 2. Power loss: When changing the oil, viscosity selection is the most basic factor. If the viscosity is too high, it can cause the friction surface to overheat, resulting in unnecessary power loss. 3. Wear: If the viscosity is too low, the oil may be thrown off the gear surface due to centrifugal force, which can easily lead to oil seal leakage, potentially forming thin lubrication on the gear surface, thereby increasing wear or even causing sintering. Below are the precautions for using gear oil: 1. Addition: Add and change it in a timely manner. 2. Oil change: Change the oil promptly. 3. Lubricating oil: Avoid getting lubricating oil or grease on the generator, starter carbon brushes, and rotor of the vehicle.

I've driven manual transmission cars for half my life, and I always pay special attention to gear oil changes during maintenance. Generally speaking, the gear oil in manual transmissions should be replaced every 40,000 to 60,000 kilometers - that's the standard I've established through years of experience. If you frequently drive in congested urban traffic, the wear will be faster, and I recommend shortening the interval to 30,000 kilometers. Checking the oil quality is also important: if the drained oil appears black or has excessive viscosity, it means it's overdue for a change. Owners who frequently haul heavy loads or drive on hilly terrain need to be even more cautious, otherwise excessive gear wear can make shifting feel rough, and repairs can be quite expensive. When I was younger and less careful, I once waited until the oil deteriorated before changing it, which resulted in a transmission repair costing several thousand dollars - a decision I deeply regret. Regular maintenance saves both peace of mind and money.

When I bought my first car, I was clueless about maintenance. Later, I checked the vehicle manual and learned that gear oil should be changed every 50,000 kilometers. Now, during every service, I remind the mechanic to inspect the transmission section to ensure the fluid is fresh. If you frequently drive on highways, the interval can be extended to 60,000 kilometers; but if you frequently start the engine or climb steep slopes, it's better to change it earlier, at 40,000 kilometers. Don't overlook older vehicles—oil deteriorates faster, so inspect it every two years. You can also perform a simple check yourself: pull out the transmission dipstick and inspect it; if there's an odd smell or impurities, change it immediately. Preventive maintenance can help avoid breakdowns on the road.

As a car enthusiast, I always enjoy studying internal mechanisms. Gear oil lubricates and cools the transmission system, but over time it oxidizes and deteriorates, leading to rough gear shifts. The standard oil change interval is 40,000 to 60,000 kilometers. However, if driving conditions are harsh (like frequent mountain driving) or low-quality oil is used, it's recommended to shorten the interval to 30,000 kilometers. Also, don't forget that differential oil needs to be changed simultaneously – most vehicle manuals provide clear recommendations. When I change the oil myself, I often find metal shavings in the old oil, reminding everyone that timely maintenance can extend a car's lifespan. In high-temperature areas, special attention should be paid to oil temperature increases accelerating deterioration. Timely replacement is crucial.
