Many owners in the purchase of a new car, sales staff will often tell, in accordance with the requirements of the maintenance manual for vehicle maintenance. However, in the process of use, many owners often encounter such a problem, the original maintenance mileage is 7500 kilometers, but just to 5000 kilometers, after-sales staff urged the past maintenance. And once the first guarantee is ahead of schedule, it means that the following maintenance cycle should be ahead of schedule, is such a course of action correct?

For the current owner not to the mileage maintenance behavior, Jin Shuntong senior coach coach Zhou told reporters, in fact, advance maintenance is not completely the owner behavior, but some dealers in order to after-sales profit, deliberately shorten the maintenance mileage. This kind of situation especially happens in the vehicle first protection stage.

The coach believes that the first insurance is not necessary to "deliberately" advance. However, the data and time provided by the manufacturer are in an ideal situation, and the actual maintenance time and cycle may be shortened. As for routine maintenance, it is also related to the brand and use of the car. It is generally maintained every 5000 kilometers or 3 months on average. Especially, it is very important to change the oil, because the oil has a shelf life. If the car is less used and in better condition, it can be extended to six months.

In addition, many owners drive for a period of time, they will add some so-called "supplements" to their cars. In fact, this approach is also not advisable.

In this regard, the coach reminds the owner, how to maintain the car is the concern of each owner, but excessive maintenance can sometimes backfire and accelerate the "aging" of the car.

Oil is not suitable for frequent change

Car maintenance cycle refers to the interval mileage (matching, picture, inquiry) or time of car maintenance. High frequency of maintenance is not a bad thing, it can protect the performance of the vehicle more effectively, but too often is not necessary. Many new cars can basically change the oil every 10,000 kilometers if they use synthetic oil under normal driving conditions, and some can even be towed for 20,000 kilometers.

In addition, not only the new car is not suitable for oil change too often, but also is not suitable for too full, if the new car oil is too much, the engine crankshaft handle and connecting rod big end will produce violent agitation when working, increasing the internal power loss of the engine, but also make the oil splash on the cylinder wall increase, resulting in burning oil failure. The oil in the engine oil pan should be controlled between the upper and lower lines of the oil gauge.

All sorts of extras have pitfalls

Many owners like to upgrade the original car audio, navigation and reversing image, replacement of leather seats, chassis armor, etc., the full set down may cost tens of thousands of yuan.

But the coach warned that not only most of the added things are not practical value, some because of changes to the original car's circuit, but also bring safety risks.

Tires should not deliberately pursue imports. Some people especially like to emphasize the "import" of tires, and professionals remind that the new tires pushed by foreign countries are not suitable for domestic users.

Foreign smooth road surface and domestic road conditions have a big difference, suitable for foreign road conditions of the tire, on the domestic road may not have a good performance, especially the impact resistance of the tire side is obviously some accusers.
