Don't mix the car with oil

Have you had experience with car engine oil mixing? If yes, then you can only say that you don't love your car enough. It should be noted that the oils of different brands or manufacturers are different in their composition, and chemical reactions may also occur between different components, thus changing the original quality. To be serious, it may shorten the service life of all parts of the engine, so we should treat it correctly.

The role of oil

Engine oil, also known as engine oil, is like a car's blood. It mainly plays a role in lubricating, cleaning, cooling, sealing, and reducing wear of automotive engines.

Mixed oil hazards

Although the types and viscosity grades of different brands of oils are the same, there are some differences in the chemical composition of the lubricants produced by different manufacturers. Addition of lubricants formulated with additives of different chemical compositions may cause chemical reactions between the additives. Therefore, when replacing the oil, the old oil in the engine should be drained. It is better to flush the system with new oil and then inject new oil.

In addition, the owner can best develop the habit of checking the oil every week. For new cars, the components of the power train and cooling system are relatively young. There is no such phenomenon as “burning oil” or “pipe aging”, and there is no need to regularly replenish oil and antifreeze. However, for some old cars that have been in use for two or three years, the owner should check the level of lubricant and antifreeze liquid on a weekly basis, and prepare some of the same brand, the same type of engine oil and antifreeze on the car.

Therefore, try not to mix the car engine oil. Of course, some emergency or special circumstances are not impossible, such as going to some remote areas that do not have the oil you need. However, the use of engine oil must comply with the following principles:

First, similar products can be mixed with similar quality. To adjust the physicochemical properties of the oil's viscosity, etc., it is possible to use different brands of the same oil for mixing, but this method is best to find a professional master to confirm.

Note: High-quality oils mixed with low-quality oils can be used as low-quality oils. Remember not to use them as high-quality oils.

The second is that for different types of engine oils, if it is known that two kinds of oils that are going to be mixed are additive-free or one of them is additive-free, and either two kinds of engine oils are additive but do not react with each other, this is generally also the case. Can be mixed. Under normal circumstances, mineral oils can also be mixed, and more mineral oils and semi-synthetic oils can be mixed. It should be noted that the mixture between synthetic oil and mineral oil should be careful. If you do not understand it well, try to avoid mixing.

In general, if it is not an emergency, the oil should not be mixed as much as possible. If it is used, please follow the above principles. In the end, Xiao Bian reminded everyone that gasoline engine oil and diesel engine oil must not be mixed, resulting in loss of engine shimming and wear.
