The oil change interval should adhere to the standards set by the manufacturer, typically determined by the duration of use or the mileage covered. Different vehicle models and types of engine oil have varied replacement cycles. It is essential to refer to the vehicle's user manual and maintain the vehicle as prescribed.
Taking the Audi A4L as an example, the manufacturer recommends changing the engine oil every 10,000 kilometers or once every 12 months, whichever comes first.
Inside the engine, the pistons and cylinder walls, along with other metal surfaces that rub against each other, move at high speeds in a unique environment with high operating temperatures. Under such conditions, only qualified lubricating oil can reduce wear and tear on engine parts and extend their lifespan. Insufficient oil performance might lead to issues like cylinder scuffing and piston ring seizing, potentially resulting in severe engine malfunctions.
