What does the oil and filter maintenance reminder mean?

[ElenaMarie]

The dashboard displaying maintenance oil and filter is a reminder to change the car's engine oil and oil filter. Below is additional information: Cars should have their oil changed regularly: Basically, every car's manual will clearly state this. The previous standard was every 5,000 kilometers, but in recent years, car manufacturers have continuously researched and developed to improve engine construction, extending the time required for regular maintenance and oil changes. Therefore, many new cars under normal driving conditions, if using synthetic oil, can basically change the oil every 10,000 kilometers, and some can even go up to 20,000 kilometers. Automotive maintenance professionals believe that "normal driving" refers to frequently driving on highways with little stop-and-go traffic. However, if you often drive in the city, encountering traffic lights everywhere, frequent traffic jams, and most trips not exceeding more than ten kilometers, this type of driving is considered "severe driving." Engine wear: Under "severe driving" conditions, engine wear is greater, and the requirements for oil are also higher. Therefore, it is recommended to shorten the oil change interval to effectively protect the engine.
