car maintenance

Regarding maintenance mileage, many car owners are superstitious about changing oil at 5,000 kilometers and changing coolant at 20,000 kilometers. However, as long as you open the manual and read it, you will find that the maintenance mileage of each car is different. Nowadays, many models have oil mileage. The coolant of some models can even be used for 100,000 kilometers before it needs to be replaced. These vary from car to car.

When changing the engine oil, some people think that the maintenance guy is cutting corners by not pouring out the entire bottle of engine oil. But in fact, how much engine oil should be added should be based on the oil dipstick. The oil capacity of many models may not be exactly enough for a full bottle. You should know that too much engine oil will increase engine resistance. Excessive engine oil will also cause "oil burning", which will lead to the failure of the three-way catalytic converter.
