How much engine oil remains before maintenance is needed?

[VonTeagan]

Generally, when the engine oil level drops below approximately 10%, it's time for maintenance. Additionally, regular maintenance can be scheduled based on the oil's service life. Engine oil replacement intervals: Engine oils are categorized into fully synthetic oil, semi-synthetic oil, and mineral oil. For fully synthetic oil, replacement is typically required every 10,000 kilometers or once a year. Semi-synthetic oil should be replaced every 7,500 kilometers or every seven to eight months. Mineral oil requires replacement every 5,000 kilometers or every six months. Other fluid replacement intervals: Brake fluid should be replaced every 20,000 to 40,000 kilometers or every two years. Coolant should be replaced every one to two years. Hydraulic oil should be replaced annually or every 10,000 kilometers.
