When should the Buick LaCrosse be serviced based on remaining oil life?

If using mineral oil, semi-synthetic oil, or full synthetic technology oil, the maintenance interval is generally 5,000 kilometers or six months. For full synthetic oil, the interval is 10,000 kilometers or one year. Whichever comes first, mileage or time, should be followed. During service, replace the engine oil and oil filter, and check the cleanliness of the air filter and cabin air filter. Then decide whether to clean or directly replace them based on actual conditions. Related information: Oil life: Oil life is automatically calculated by the vehicle's central control software based on engine operation. There is a parameter setting involved, so it is not mandatory to change oil strictly according to the oil life indicator. Follow the manufacturer's recommended mileage (under normal conditions, this is already the shortest oil change cycle tested with factory-recommended oil), supplemented by simple judgment methods. Self-check method: Periodically use the oil dipstick to place a small amount of oil on your finger. If the oil drop forms three concentric rings (inner black ring is dirt, outer light ring is oil, and the middle ring is a mixture of oil and dirt) with clear boundaries, it indicates the oil can still be used. If the rings become indistinct, completely black, or watery, and there is an increased gritty feeling when rubbed between fingers, it means the oil has reached the end of its life (deteriorated) and should be replaced immediately.
