I heard that the vehicle has to change the oil every 5,000 kilometers? This statement is a little extreme and partial generalization, how much is the replacement cycle of the oil, why is the concept that 5000 kilometers must be changed? Can you judge whether the oil should be changed? These questions will be answered one by one by the editor.
Oil
Engine oil is also known as engine lubricating oil, its main functions are lubrication and friction reduction, auxiliary cooling and cooling, sealing and leak-proof, anti-rust and anti-corrosion, shock absorption buffer, etc., it is no exaggeration to say that it is the blood of the car. There are two components of the oil, namely the base oil and the additive, the base oil is the cornerstone and the additive is a kind of icing on the cake, which can open up new properties for the oil and improve the original deficiencies.
We see on the Internet 5000 to 10000 km or half a year to replace the cycle, in fact, corresponding to different quality of oil, oil can be divided into three kinds: mineral oil, semi-synthetic oil and fully synthetic oil, mineral oil use cycle is the shortest, about 5000 km or half a year to replace once, semi-synthetic oil followed by about 7500 km or nine months to replace once, Fully synthetic oils can be used up to 10,000 km or replaced once a year.
In this respect alone, the argument that 5,000 km must be changed has been broken, unless mineral oil is used. However, the oils on the market are basically fully synthetic oils, and the service life is much greater than 5,000 kilometers. Just like this oil, its quality standard is the highest SP grade today, and it is better at dealing with low-speed early combustion, oxidation resistance, wear resistance, and fuel economy.
Not only that, as mentioned above, there are additives in the components of the oil, additives can bring new properties to the oil and improve the deficiencies, if the role of the additive is to extend the service life of the oil, the use mileage of a fully synthetic oil will be much higher than 10,000 kilometers.
The oil replacement cycle is larger, 5000 to 10000 kilometers is no problem, to a smaller extent, it depends on what oil you add. Can not use the fully synthetic oil results also 5,000 kilometers to change once, that is to spend money unjustly.
Self-test
In fact, the oil can be checked by itself, and it does not necessarily need to be completely lost to the store for maintenance, and you can pay attention to the condition of the oil in advance or often. In fact, the self-test is not complicated in total, two steps, first pull out the oil gauge, through the liquid level marks on the oil gauge can judge the residual amount of oil at this time, if the vehicle appears to burn oil or oil leakage, the liquid level will be lower than normal. As long as the oil level is between the highest and lowest values, there is no problem.
In addition to helping us determine the oil margin, the oil gauge can also help us determine the condition of the oil. The new oil is clear, transparent and no odor, the darker the oil color, the more it means that the oil has not been changed for a long time, and the appearance of the odor also implies that it is time to change the oil.
brief summary
Engine oil for the vehicle is like blood, so when changing the oil can not be greedy cheap, go to the regular store to buy genuine products to really protect the engine, Xiaobian believes that in terms of maintenance can not be saved, at least not too provincial.
