How many days to change the best oil how much time to change the oil for this problem, we must first understand the replacement cycle of different oil, such as mineral oil, its service cycle is generally 5,000 kilometers or six months; In addition, the service life of semi-synthetic oil may be longer, which can come to about 7,500 kilometers; And the full synthetic oil 10,000 kilometers or a year, this is our daily access to maintenance knowledge, but the full synthetic oil can really only use 10,000 kilometers?

In fact, different types of oil, their replacement cycles are not the same. If it is mineral oil, it is generally replaced once for half a year or about 5,000 kilometers. If you use semi-synthetic oil, replace it once every 7-8 months or about 7500 kilometers. The fully synthetic oil is replaced once a year or about 10,000 kilometers. However, the oil replacement cycle can only be used as a reference, and the specific depends on the driving of the vehicle.

If you usually rarely use the car, it may be half a year to open about 3000 kilometers, at this time we are considering extending the oil replacement cycle. Of course, if the economy allows, early replacement is more able to ensure the working efficiency of the oil. If it is a new car, it must be replaced in strict accordance with the prescribed cycle. After all, during this period of the run-in period, the metal debris generated by the engine is very much, and the efficacy of the oil needs to be ensured.

If you often use the car to commute, it is inevitable that you will encounter the rush hour of congestion, and the situation is particularly serious in first-tier cities. Then the car in a long idle state, will affect the service life of the oil, so it is recommended to replace 1000 kilometers or 1 month in advance.

Oil test paper method: First pull out the oil gauge next to the engine, and then take out a small amount of oil drops on the oil test paper, and put it stationary for a night, waiting for the oil to completely spread on the test paper. Then you can observe the deposition ring, oil ring and diffusion ring on the test paper, if the following three situations occur, it means that the oil needs to be replaced
