The Great Wall is very cold.

There is basically no need to change the oil. It's good to use Great Wall engine oil, but I want to remind you that it's best to pay for the oil change before 2000, because there will be a lot of iron filings in the engine power of the new car. If we switch to 2000, it will be much better for the engine. I just didn't pay attention to these problems when I first bought a car. Now the engine power of the same car is not as good as others. The difference between cars bought together.
