The current engine is generally lubricated with engine oil, but generally only one type of engine oil is stored in the oil pan for storing engine oil in the engine. There are a variety of engine oil models available in the market, each type of engine oil has an optimum working environment temperature range, beyond this optimum working environment temperature range, the lubricating performance of the engine oil will decline, in severe cases will damage the engine. In countries with a large latitude span like China, there is a large temperature difference from the northernmost point to the southernmost point in winter. If the car is driven from the northernmost point to the southernmost point or from the southernmost point to the northernmost point, in order to make the engine better , It is necessary to change different oils halfway to adapt to different temperature environments. At present, a switching device that can store two kinds of engine oils at the same time has been invented, but there is a problem that the two kinds of oils are mixed during use.
