How many kilometers should a new car run for the first time to change the gear oil?

Generally, the first gear oil change should be done at 2000 to 3000km, or this replacement cycle can be advanced. Here is more information about gear oil: 1. Brief description: Gear oil mainly refers to the lubricating oil for transmissions and rear axles. 2. Functions: Lubricate the transmission system, reduce wear on gears and their moving parts, ensure the normal operation of the transmission system, and extend service life; Cool transmission components, as gear oil continuously carries away heat during the circulation lubrication process, ensuring the normal operation of transmission components; Prevent corrosion and rust, with a cleaning effect that continuously washes away pollutants and solid particles deposited on the gear surfaces; Reduce gear surface impact and transmission noise.

Let me share my personal driving experience regarding the first gear oil change mileage for new cars. Generally speaking, new cars should have their gear oil changed between 5,000 to 10,000 kilometers. During that break-in period, the engine and transmission are adapting to each other, and the oil may accumulate metal particles - changing it early protects mechanical components. I remember changing the oil in my first car at 7,000 km, and it immediately ran noticeably smoother. If you frequently drive in congested urban areas or poor road conditions, you might need to change it at 5,000 km; if you do more highway long-distance driving, you could stretch it to 8,000 km. Always consult your owner's manual as requirements vary by brand - Japanese cars often have stricter intervals. Neglecting this accelerates wear and causes rough shifting. Truth is, oil quality during the new car phase affects the vehicle's entire lifespan. Spending a little on fresh oil now is better than costly transmission repairs later. Don't delay too long - get it checked during the first maintenance service.

When I first bought a new car, I pondered the timing for gear oil replacement. Generally, the first change is recommended around 6,000 to 8,000 kilometers, but it depends on the vehicle model. Automatic transmission cars often suggest changing at 8,000 kilometers, while manual transmissions might require it as early as 5,000 kilometers. During the break-in period of a new car, the oil contains impurities, so the first replacement helps clean them out, improving performance and longevity. When I drove a manual transmission, changing the oil at 7,000 kilometers made the car feel smoother. Don’t rely solely on memory—check the maintenance manual for specific guidance. Driving habits also play a role—if you frequently accelerate hard or drive on mountainous roads, consider changing it earlier. Delaying the first oil change in a new car may lead to increased noise or sluggish gear shifts over time. When sharing experiences with friends, most advised not to exceed 10,000 kilometers. Also, remember to check the oil level regularly to ensure safe driving.

Regarding the first gear oil change for a new car, I'll speak from a practical perspective. It's recommended to perform the change between 5,000-10,000 kilometers. Replacing the oil after the break-in period helps prevent long-term issues. For example, if you frequently drive in urban areas or dusty regions, changing it at a shorter interval is better. This contributes to smoother transmission operation and extends service life. I always pay attention to this during each maintenance - beginners shouldn't skimp on this expense.
