First of all, we need to explain what is oil and filter. Oil is the engine lubricating oil, engine lubrication antifriction, auxiliary cooling, sealing, rust corrosion, shock absorption effect. The engine has a lot of friction between the movement of the metal surface, these components fast movement, poor environment, the operating temperature of up to 400° C to 600° C. In such harsh conditions, only qualified lubricants can reduce engine parts wear and prolong service life. The oil used for a period of time, from the transparent yellow into the muddy dark, it needs to be replaced, the different models need to add different oil, according to the vehicle itself, at the same time as a result of climate change, especially in the winter should add appropriate oil. Need to remind everyone that the 4S store in free maintenance for customers to add are generally specified in the original ordinary mineral oil, but in the subsequent regular maintenance payments, will allow you to use synthetic oil more expensive, but the use of expensive synthetic oil cycle can be as high as 8000 to 12000 kilometers.
