There is no fixed and uniform replacement cycle for oil filters, and the core depends on the type of oil used, vehicle operating conditions, and driving environment. Accurately matching the cycle is necessary to balance maintenance effectiveness and cost-effectiveness.

Firstly, mineral engine oil is paired with a regular paper filter, with a suitable replacement cycle of 5000 kilometers or 6 months. Mineral engine oil has poor antioxidant properties and generates impurities quickly. The capacity of ordinary machine filters is limited and must be replaced in the short term to avoid filter saturation and failure.

Next is the combination of semi synthetic engine oil and mid-range oil filter, with a replacement cycle of 7500 kilometers or 9 months. Semi synthetic engine oil has better stability than mineral oil, with less impurity production. Combined with an improved filter, it can stably support mid-term maintenance cycles.

Finally, the fully synthetic engine oil is paired with a long-lasting fiberglass filter, with a replacement cycle of 10000 kilometers or 12 months. Fully synthetic engine oil has high purity, antioxidant properties, and is not prone to sludge formation. Its long-term filter capacity is 1.5 times that of ordinary filters, perfectly adapting to the rhythm of long-term maintenance.

In addition, harsh working conditions require a shorter replacement cycle. Long term urban congestion, short distance driving, dusty road conditions, heavy load driving, and use in low-temperature northern regions result in faster filter wear and require a reduction of about 20% in replacement mileage. Strictly following the adaptation cycle for replacement can effectively protect the engine and avoid waste caused by excessive maintenance.
