Can I mix different brands of motor oil?

Can different brands of the same brand of engine oil be mixed with each other, and what are the consequences?

No, the oil models can't be mixed, and the brands can't be mixed! Each type of engine oil has its function, the function is different, the process and additives are also different, the mixing of engine oil is equivalent to polluting the oil itself, resulting in the decline of oil performance and other problems! Hope it helps.

It's best not to, the ratio may be slightly different.

You can mix it, but it's not recommended, and if it's for "emergency", you can deal with it. It should be noted that no matter how many engine oils are mixed, the oil label and grade need to be the same, such as the same fully synthetic 5w-30 or the same fully synthetic 5w-40.

It is best not to mix different brands of engine oil, each manufacturer's products are different, which is not good for the machine! It's best to clean up the old oil and add new oil from the new one!

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Summary. Engine oil can lubricate and reduce friction, seal and leak prevention, rust and corrosion prevention, shock absorption and cushioning of the engine. Base oil is the main component of lubricating oil, determines the quality of lubricating oil, additives can make up for and improve the lack of base oil, is an important part of engine oil, engine oil is composed of base oil and additives.

Hello <> dear! We are glad to answer that engine oil cannot be mixed with different brands. Different brands of oil can be interchanged, but they cannot be mixed.

The types of engine oil additives are different, the performance is different, and the preferred functions of different brands of engine oil are not the same, provided that the viscosity is the same, which will affect the xing energy of the engine oil.

Engine oil can lubricate and reduce friction, seal and leak prevention, rust and corrosion prevention, shock absorption and cushioning of the engine. Base oil is the main component of lubricating oil, which determines the quality of lubricating oil, additives can make up for and improve the shortcomings of base oil, and is an important part of engine oil, which is composed of two parts: base oil and additives. Bureau.

Car owners can mix different brands of engine oil when refueling their cars, but I don't recommend using them like this. If it's for an emergency, you can do that. If you have to do this, it is important to note that the grades and grades of the oils you are mixing must be the same, for example, both oils are fully synthetic 5w30 oil or both oils are fully synthetic 5w40 oil.

The defects that will occur when mixing different brands of engine oil are:

1. Turbidity: Nowadays, most of the dispersion detergents you can buy are sulfonates, and only a very small number of dispersion detergents used in engine oil are salicylates.

2. Exhaust abnormality: In the case of mixing different engine oils, it is easy to cause abnormalities in the exhaust system of the car, and even make the car smoke, which may cause the car to emit black smoke or blue smoke in the process of driving. This can also lead to poor cylinder sealing, which can cause the car to emit black smoke.

3. Sludge: The mixing of different types of oil greatly aggravates the situation of sludge, and the destructive power of sludge is very strong, which will greatly reduce the heat dissipation effect of lubricating oil, resulting in an increase in engine temperature, resulting in a series of failure problems.

4. Accelerated wear: If different oils are mixed, the internal wear resistance will be seriously damaged, the oil bun will be damaged, the piston and the cylinder wall are very prone to wear, and when the wear is serious, there may even be a fracture of the piston ring.
