Can Synthetic Engine Oil Still Be Used After 13,000 Kilometers?

[Bethany]

Synthetic engine oil that has been used for 13,000 kilometers is best not to continue using, as it poses significant risks. Below are the classifications of engine oil: 1. Diesel Engine Oil: There are two main criteria for selecting the quality grade of diesel engine lubricating oil. One is based on the combined mechanical and thermal loads of the automobile engine, expressed by the intensification coefficient; the other is based on the severity of the engine's operating conditions. 2. Gasoline Engine Oil: The appropriate performance grade (quality grade) of gasoline engine oil should be selected based on the severity of the engine's operating conditions, the additional devices in the intake and exhaust systems of imported vehicles, and the production year. Never use a lower quality grade oil to replace a higher quality grade oil, as this can lead to engine failure or even damage.
