How many kilometers should a China V diesel vehicle change its oil?

Diesel engine oil, CF-4 grade oil change interval is 8000-12000 kilometers, CH-4 grade oil change interval is 15000-20000 kilometers, CI-4 grade oil change interval is about 25000 kilometers. The products of mainstream lubricant manufacturers can basically achieve the above oil change intervals. Diesel engine: Diesel engines are very durable. The speed of diesel engines is relatively low, and the wear of engine components is relatively reduced. At the same time, the requirements of diesel engines for oil are also different from gasoline, it needs special oil. The oil change time should not exceed 6000 kilometers. Usually, it is also necessary to strengthen the maintenance of the three filters: air filter, oil filter and diesel filter. Extend the oil change interval: Owners can appropriately extend or shorten the oil change interval according to the actual use of diesel quality, road conditions, working conditions, ambient temperature, air quality, air filter filtration effect and lubricating oil quality.
My National V diesel pickup basically follows two oil change patterns. When using conventional mineral oil, I usually check it every 5,000 km and will definitely replace it before reaching 7,000 km. But with full synthetic oil, it lasts much longer – under good road conditions, it can go 15,000 to 20,000 km between changes. The key is not to just focus on mileage; when the oil life monitor light comes on, address it immediately. In our fleet, several identical models used for hauling goods on rough roads daily require changes every three months, whereas mine primarily runs urban highways and can typically last six months. Always remember to replace the oil filter simultaneously during each oil change – otherwise, mixing new oil with contaminants from the old filter cuts the effectiveness in half.
I just helped my neighbor check the manual for his China V diesel SUV. The manufacturer recommends changing the oil every 12 months or 15,000 kilometers, whichever comes first. In practice, I've noticed that diesel engines consume oil faster than gasoline cars, especially turbocharged models. During the last maintenance, the mechanic reminded me that vehicles frequently used for short trips should change oil 30% earlier in mileage because diesel combustion produces acidic substances. If the engine isn't fully warmed up before stopping, it can lead to oil acidification. From my own experience, I check the dipstick around 10,000 kilometers. If the oil appears black or the viscosity has decreased, it's time for a change even if the mileage hasn't been reached.
