How often should gear oil be changed in a new car?
2 Answers
New car gear oil should be changed every 60,000 kilometers, which can effectively improve the efficiency of gear transmission of engine power. The selection of oil viscosity is a fundamental factor when changing oil. If the viscosity is too high, it may cause overheating of friction surfaces and unnecessary power loss. Gear oil is primarily composed of petroleum lubricating base oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents. Gear oil mainly serves to lubricate gears and bearings, prevent wear and rust, and assist in heat dissipation for gears. It is used in various gear transmission devices to extend their service life and enhance power transmission efficiency.
From my experience, the timing for changing gear oil in a new car depends on the vehicle manual. Typically, manual transmission fluid is recommended to be replaced every 30,000 to 50,000 kilometers or every 2 to 3 years, while automatic transmission fluid may extend to 60,000 to 80,000 kilometers. The first few tens of thousands of kilometers are the break-in period for a new car, and the gear oil may accumulate metal shavings. Not replacing it in time can lead to transmission wear and rough shifting. To save money, regularly check the oil level and color yourself. If it turns black or has a burnt smell, it's time to take action. Synthetic oil can last longer, but don't exceed the manual's recommendations, or the repair costs could buy you new tires. Developing a habit of regular maintenance not only protects your car but also enhances the driving experience.
