Because of traffic jam, low-carbon environmental protection, vehicle cost and other reasons, some car owners will choose public transportation to travel, so the car will be idle for a long time, and some cars can not even run 5,000 kilometers a year. How to choose maintenance is more cost-effective?

First, according to the maintenance time interval:

Usually the maintenance is calculated according to the mileage interval or two maintenance time interval.

But in this case, the replacement cycle of various parts of computer oil, filter, antifreeze and brake oil will be more accurate according to the time.

Although the car did not move, but all kinds of vulnerable parts, oil, etc., will age with the passage of time, performance is bound to be greatly compromised.

1. The performance of oil will decrease

The role of oil should be known to all, mainly for the engine cleaning, cooling and lubrication, to ensure that the engine working internal parts to reduce wear, but also seal leakage, rust and corrosion. Therefore, oil is normally consumed very little, and the reason why we need to change oil is because the esters and polyenes in the oil will oxidize. In addition, the engine parts wear particles will also enter the oil, so that the life of the oil is reduced, the internal composition deterioration. For example, the SN grade full synthetic oil replacement cycle is 10,000 kilometers or one year, whichever comes first. Even if you don't run to 10,000 kilometers, you should replace it after a year.

2. Brake oil and antifreeze also have fixed age requirements

Brake oil has strong hygroscopicity and will absorb moisture in the air, especially in humid environment. When the moisture of brake oil reaches, it will cause safety hazards; Therefore, it is usually checked and replaced once every 2 years.

The antifreeze in most family cars is replaced every two years or 40,000 kilometers. But when the level of the antifreeze water bottle is lower than the MIN line, it should be added in time to make the liquid level located

Two, can be replaced with longer time accessories

Because it's less open, it's more cost-effective to replace parts that last longer. Its timeliness can be emphasized.

For example, oil, we all know that the market oil, divided into mineral oil, semi-synthetic oil, synthetic oil three. Among them, all-synthetic oils have a longer life, better protection and better performance for automobile engines.

And from the cost of car maintenance, mineral oil should be changed at least twice a year; The synthetic oil is enough once, and the overall price is more cost-effective when you add in the cost of gas, working hours and so on.

In the same way, antifreeze, machine filter, tire and so on can be replaced with a better and more durable brand, so that it saves money and worry, the effect is better than the original, the car is also better, is a good choice.

Finally, driving less, but also pay attention to what?

1. Use less, pay attention to battery loss

If the usual place to use the car is really few, but also pay special attention to the aging battery. In the state of complete stagnation, the same power consumption will occur; Coupled with the electrical equipment in the car is also more, over time will cause battery loss.

It is recommended that the duration of each ride should not be less than

2. Don't add too much oil at a time

Gasoline itself has a certain amount of sulfur, nitrogen impurities, if you add more oil, put for a long time, it is really possible to produce glia through oxidation reaction. Then after combustion, will produce carbon deposition, affect the normal work of the car, and the consumption is higher than the original.

3. Clean the body

The car paint is exposed for a long time, there will inevitably be dust on it, when ready for a long time not to use, it is best to clean, so as not to fall on the car paint for a long time, serious such as acid rain, bird droppings, these two on the car paint damage the most; Finally, park in the shade to avoid the sun!
