What kind of oil should I change for the second maintenance of the car?

Hello, it is recommended to replace the original engine oil. Considering the cost, domestic engine oil such as Great Wall can be considered, which is very cost-effective. The replacement cycle of synthetic engine oil will be longer, generally around 10000 km, and the replacement cycle of semi-synthetic products is around 7000 km. But the price in synthetic engine oil will be higher. If there is no requirement for cars, half synthetic engine oil is enough.

The second maintenance of the car needs to replace the oil, oil filter, gasoline and filter, clean or replace the air filter, clean the air conditioning filter and so on.

General car maintenance is mainly divided into two aspects:

First, body cleaning: internal cleaning for 3 -6 months; Especially when the seasons alternate, in addition to the center console, we should also consider the inside of the car; Including air conditioning duct, under the seat, etc. Outside the vehicle, wash the vehicle after rain, and clean up bird droppings and insect carcasses in time; Waxing once a month or so;

The second is vehicle maintenance; Not to mention vehicles, any mechanical equipment should be carefully maintained; Experts know a truth: that is, "nurturing" is more important than "repairing"; Maintenance in place, not just for safety; At the same time, it can greatly prolong the service cycle and service life of vehicles; Reduce costs; Get twice the result with half the effort.
