Engine-oil timing depends on the vehicle maker's schedule, oil specification, traffic pattern and the condition of the engine.
In Bangladesh, frequent stop-and-go driving, dust and short trips make it useful to review the service schedule together with the actual vehicle condition. Check the oil level correctly, use the specified grade and record the service date.
If the vehicle has leaks, unusual noise or an oil warning, arrange an inspection instead of relying only on a calendar reminder.
