听力原文：M Thank you for calling Green Valley automotive. How may I help you? W Hello, I have a question about routine oil changes. I just bought a new car and was wondering how often I should come in and have the oil changed. M It's really important to have the oil in your car changed every 10,000 km to keep your car's engine running smoothly. If you don't do it regularly the engine will start to overheat and deteriorate. It's not expensive to have done you should really bring it in. How many kilometers are on the car? W Right now the odometer says it has 10,500 km, I'll bring it right in. What does the man do?
