Will using fake engine oil have any impact on driving? What is fake engine oil made of?

Motor oil is also known as engine lubricant, which is mainly used in the engine and is a necessity for cars. Some merchants will make fake motor oil to impersonate branded motor oil, which will definitely affect the engine over time. So will using fake motor oil affect driving?

Will using fake engine oil have any impact on driving?

In fact, after adding fake engine oil, our car engine generally will not have any big reaction. Under normal driving conditions, we may not even feel that there is anything unusual with the engine.

However, if the quality of the fake oil is too poor and the performance is seriously unqualified, then after using the fake oil, the engine will make a lot of noise, which will also cause the engine temperature to be too high and the oil pressure warning light to light up.

Therefore, if we change the engine oil, we will immediately find that when the car is running, the engine noise will increase significantly, and the oil pressure warning light is likely to appear, or the water temperature warning light (less likely). Once this problem occurs, we must consider whether it is a problem with the engine oil.

What is fake motor oil made of?

One is to recycle waste oil, which is mainly the waste oil replaced by some repair shops and 4S shops. It is processed by means of sedimentation, filtration, etc. and then repackaged as good quality oil.

Another method is to directly bottle and sell the most original embryonic oil. Although it is better than recycled waste oil, embryonic oil does not contain any anti-wear agents, metal protectants or other chemical agents that stabilize the oil quality. Under high temperature working conditions, the viscosity of the oil will change.

Another method is to buy some low-grade motor oil at a low price, and then fill it with high-grade motor oil barrels for sale. For example, mineral motor oil is sold as semi-synthetic motor oil, semi-synthetic motor oil is sold as fully synthetic motor oil, and even the same batch of motor oil is sold as different models such as 5W-30, 0W-40, etc.!

Another type is foreign barreled motor oil that is canned in China. It can be said that this type of fake motor oil is very real and conscientious, at least the base oil is not bad. You should know that branded motor oil is just base oil + secret recipe. The lubrication effect is of course mainly based on the base oil. The secret recipe (additives) will play a role in anti-oxidation, cleaning ability, and coating. Although this type of motor oil is fake, it basically will not cause major problems to the vehicle because the base oil is not bad.

How to distinguish genuine and fake motor oil

price

This is of utmost importance. It is almost impossible to buy a first-line brand fully synthetic motor oil for one or two hundred yuan. A reasonable price is about 10 points lower than the official price. If it is 20 points lower, there is basically a problem.

color

Genuine engine oil is generally golden yellow and has good permeability. If the color is too dark, it is basically fake engine oil. The slightly light blue color is due to the changes caused by additives and is a normal phenomenon.

smell

Real engine oil has a light fragrance without any other odor, while fake engine oil often has a pungent odor or even the smell of fuel. This odor will cause a strong reaction in the nasal mucosa and is easy to identify.

Fluidity and viscosity

When adding engine oil, if the oil flows evenly without any obstruction and feels smooth without any graininess when rubbed with hands, it is real engine oil. If it feels a little cold (not caused by ambient temperature) or has poor fluidity, it can be judged as fake engine oil.
