The so-called five oils refer to transmission oil, engine oil, brake oil, power direction oil, gasoline and other items. Sanshui refers to tank water, battery water and wiper water.

And how often should five oils and three waters be replaced? If the owner buys a new car, suppose the car factory tells him that he must go back to the original factory for maintenance after driving 5 thousand kilometers for half a year, but the owner only runs 2 thousand kilometers for half a year. Is it necessary to enter the factory for maintenance? From the safety point of view, maintenance must be carried out when it reaches 5 thousand kilometers or half a year, that is to say, when it reaches one of the conditions of mileage or time, it must be repaired once in the factory.

Even if you don't drive frequently, the unsealed oil will oxidize and deteriorate for a long time. Even if the mileage is not reached or the frequency of car use is not high, but the replacement standard is reached by time, it still needs to be maintained in the factory. For car owners who use cars frequently, car parts or accessories are easy to consume and age, so when the car reaches the mileage specified in the car maintenance, it must be maintained in the factory.
