In the case of using the original engine oil, we need to replace the engine oil according to the instructions in the maintenance manual.
After the new car was bought back, it was maintained in the 4S shop. The maintenance engine oil was also the so-called original engine oil. In this case, it is only necessary to follow the cycle of the instructions in the car care manual to change the engine oil.
For example, most Japanese cars are 5,000 kilometers or half a year, and most of the cars in Europe and America are 7500 kilometers or half a year. However, it is recommended that the first maintenance can be advanced in advance, because the engine is in the first running-in period before the first insurance, there will be more mechanical debris will appear in the engine. It’s absolutely good for the engine to “put out” them earlier and it’s no harm to the engine.
For the engine oil bought by yourself, there will be different replacement cycles according to the type of engine oil.
If the replacement engine oil is purchased by yourself during maintenance, it is necessary to distinguish the replacement cycle according to the different types of engine oil. The previous oil article was written. The engine oil is divided into three categories: mineral engine oil, semi-synthetic engine oil and full synthetic engine oil. The replacement cycle of these three types of engine oil is also different.
Generally speaking, the replacement period of mineral oil is half a year or 5000 km, semi-synthetic oil is half a year or 7500 km, and full synthetic oil is half a year or 10,000 km.
Unconventional driving conditions also need to shorten the replacement cycle
However, whether it is the guidelines in the maintenance manual or the recommendations of the self-purchasing oil itself, it refers to the replacement cycle in the case of “general driving”. “General driving” refers to driving on the highway often, rarely stopping.
And in the city driving, traffic lights and traffic jams cause the car to idle for a long time or stop and go, often driving within a short distance of less than 8km, driving to work, but the unit car is still not hot. These are unusual “depleting driving”. This “dissipative driving” can result in a large amount of carbon deposits in the engine, which affects the life of the engine.
Like this “depleting driving”, we recommend reducing the oil replacement mileage by 20-30%. By shortening the action of replacing the mileage, the carbon in the engine is cleaned to ensure the normal operation of the engine. Specifically, how much is shortened? For example: ordinary minerals are not changed to 3500-4000 km in advance, semi-synthetic engine oil is changed to 5500-6000 km in advance; full synthetic motor oil is changed to 7500-8000 km in advance.
Poor environment should shorten the replacement cycle
In addition to “depletion driving” affecting the engine oil change cycle, the harsh driving environment will also be. Like driving on dust and gravel roads, the influx of sand and dust will increase the clogging of the oil filter and the impurity content of the oil. In this case, the effective period of the engine oil is difficult to guarantee on the original basis, so it needs to be replaced in advance.
For example, because of long-distance travel across the climatic zone, or in areas where the temperature is below -20 °C; rapid changes in climate, too low temperatures can cause deterioration of the oil, thereby greatly reducing the “life” of the oil. Like the above two cases, we also recommend reducing the oil replacement mileage by 20-30%.
