When to Change Engine Oil?

[Sawyer]

There is no fixed interval for changing engine oil, as it depends on actual driving conditions and vehicle status. Different types of engine oil have different replacement cycles. The details are as follows: 1. Engine oil can be divided into mineral oil, semi-synthetic oil, and full-synthetic oil. If mineral oil is used, it is generally recommended to change it every six months or around 5,000 kilometers; if semi-synthetic oil is used, change it every 7-8 months or around 7,500 kilometers; if full-synthetic oil is used, it can be changed after one year or around 10,000 kilometers. 2. For new cars, it is best to change the engine oil around 2,500 kilometers to better remove metal debris generated during the engine break-in period. Vehicles with low mileage can change the oil once a year, provided synthetic oil is used. For vehicles frequently driven or used in low-temperature conditions, it is recommended to change the engine oil and oil filter every 5,000-7,000 kilometers for optimal performance.
