After the first warranty of the new car, the dealer will inform the future maintenance to arrive at the store in time according to the maintenance manual. But in most cases, when it comes to the next time to do maintenance, many people are in trouble again.

In the manufacturer's vehicle maintenance manual, for the engine oil maintenance, in addition to the mileage, it will also require time.

It is according to the mileage or according to the time, you want to say, we can follow the "first to the principle" is the safest approach, simply put, open more mileage, open less time.

From the maintenance manual, each car brand has different standards for changing the oil, but generally speaking, as long as it is in accordance with its prescribed mileage and time, in advance or slightly delayed some time to do maintenance, the problem is not big.

However, it should be noted that the different levels of oil products added to each car will also directly affect its replacement cycle, and some car oil is more advanced, and its durability will be relatively better.

Generally speaking, if the engine uses mineral oil, basically 5000 km /6 months for a change, semi-synthetic oil can be 7,500 km /8 months for a change, and fully synthetic oil can reach 10,000 km /12 months for a change.

Of course, some owners usually do not have much opportunity to drive, which leads to the specified maintenance time, but the driving distance is far less than the specified mileage.

For example, if you drive less than 5000 kilometers a year after the first guarantee, and add fully synthetic oil, then can you always leave it alone and change it to the specified mileage?

In fact, even if the car is not open, it can not be changed for a long time without oil and maintenance. Because from the oil product itself, it also has a shelf life, and if the oil is not replaced for a long time, the oil viscosity will be reduced, and it will even deteriorate and emulsify, thus losing the original performance.

One of the functions of the oil is to help the engine reduce the wear between the various components, if the anti-wear performance is reduced, then the direct damage is the engine. Therefore, even if you usually do not drive, to the specified maintenance time, or to do engine maintenance.

Does a good oil change make it more fuel efficient?

Oil is divided into synthetic oil, semi-synthetic oil, mineral oil.

▶ Full synthetic oil quality is better, the use of cold start is more smooth, more fuel saving, longer oil change cycle, extend engine life, reduce maintenance rate; The engine block will be cleaner due to the superior cleanliness of the all-synthetic oil.

▶ Semi-synthetic oil is the ideal transition product from mineral oil to synthetic oil.

Mineral oil is basically extracted from crude oil, usually at a lower cost, but because the mineral oil base is easier to oxidize, although today mineral oil has added various imported additives, but the service life is still about six months.

When conditions permit, adding full synthetic oil is the best choice for vehicles, of course, better performance, but also more fuel efficient.
