3.Observe the driving experience: If the vehicle accelerates weakly, fuel consumption increases, or the engine noise becomes louder, it may be a sign that the lubrication effect of the engine oil has declined.
4.Reference vehicle tips: Modern vehicles are often equipped with an oil life monitoring system, and you can replace it according to the prompts on the dashboard.
4. Reference for engine oil replacement intervals of different models
| Vehicle type | Recommended replacement cycle (km) | Remarks |
|---|---|---|
| Ordinary family car | 5000-8000 | Use mineral oil or semi-synthetic oil |
| luxury model | 8000-12000 | Use more fully synthetic oils |
| Turbocharged models | 5000-7500 | The engine load is heavy and needs to be replaced more frequently |
