I believe everyone has a certain understanding of antifreeze, which can prevent the car from "boiling" (too high temperature) and effectively prevent the phenomenon of parking and freezing in cold areas. Then a friend reacted and found some oil slick and oil spent on it in antifreeze. It doesn't matter in the end.
In fact, it is normal for oil slick and oil flower to appear in antifreeze, so don't worry too much. However, if there is too much oil, you have to carry it separately. At this time, it is necessary to check whether the gasket of the engine cylinder is damaged. It may be that there is a problem with the oil radiator or filter, and of course there is a possibility that the seal is aging. So when this happens, you should go to the nearest garage for inspection as soon as possible.
Then, if there is a problem with the oil radiator, the oil may contain some antifreeze, so that the oil is easy to deteriorate, resulting in poor lubrication of some parts of the engine. Under continuous high-temperature operation, carbon deposition will appear in the water jacket around the cylinder liner. If it goes on for a long time, it will affect the engine to varying degrees. You should know that the maintenance cost of the engine is not low. So when you find that there is a lot of oil in antifreeze, you must find out what the problem is.
