Is the internal protection agent of the engine useful?

1. It has a certain function. It protects the engine, greatly reduces wear, prevents the engine from overheating, and prolongs the life of the engine; enhances the comprehensive performance of lubricating oil, and significantly improves synthetic oil and mineral oil.

2. The engine cleaner has a certain protective effect on the engine, but it should be noted that if it is not a frequently cleaned vehicle, it should be used with caution, because the cleaned carbon material will block the oil filter and may cause damage to the engine.

3. In fact, after some engine protectors are added to the engine, the phenomenon of engine oil burning is reduced and the cylinder pressure rises, which is caused by the engine protector increasing the viscosity of the oil, not the engine protector that repairs the wear of the cylinder.

4. In addition to the regular car oil maintenance, other maintenance needs to be done. When you go to the car 4S store for engine maintenance, you will often be suggested to apply engine protector. Is it necessary to have an engine protector? What is the use of engine protector? Many car buyers have this kind of doubt. Let's take a look together.

5. It's effective. I use the super-strong full-effect protective agent for the engine of Weili Lion.

Is it necessary to use the engine protective agent

The engine protective agent can form an extremely thin but extremely high-resistant surface in the high-temperature and high-pressure environment of the engine. The molybdenum alloy protective layer with good compressive strength and wear resistance is a layered hexagonal crystal film that can significantly reduce the friction coefficient.

The closer to the oil change cycle, the more serious the engine wear is. Oil is liquid lubrication, which cannot solve the problem of cold start and rapid start at low temperature. At the same time, with the increase of use time, the lubrication effect is inversely proportional. And the engine protector just solved this problem.

There is no need. The current engine and lubricant have beenAfter complete preparation, the original engine oil has been able to complete its mission, lubrication, sealing, heat dissipation, cleaning and wear reduction. The original engine oil already contains additives such as wear reduction, so it is not recommended to use additive products other than engine oil.

More attention should be paid to the maintenance of the engine. As the power source of the car, maintenance of the engine is particularly important. In addition to regular oil maintenance, other maintenance is also needed. When you go to the 4s store for engine maintenance, you are often advised to use engine protector.

I'll tell you very clearly: no need! The so-called engine protector is to levy your IQ tax. There are already many kinds of additives in the oil used in engine maintenance, including enhancing lubrication, removing sludge carbon, preventing metal corrosion, regulating the sticky temperature characteristics, etc., as many as a dozen additives.

Useful. Function: Anti-wear agent is added to the protective agent, which can effectively prevent the internal parts of the engine from accelerating wear, and reducing the resistance can make the engine get better power in the state of good speed. Reduce noise. Performance: ● It can effectively reduce wear and resistance, improve mechanical efficiency, and reduce engine noise.

Is the anti-wear protector of Che David's engine really useful?

1. Che David's anti-wear protector is useful, because the quality of Che David's anti-wear protection agent is reliable, the wear-resistant effect is obvious and the cost-effective, and the reputation is very good.

2. The wear-resistant effect is obvious: the use of anti-wear protector of the car David engine can significantly reduce the wear of engine parts and extend the service life of the engine.It can form a protective film to reduce direct contact with the metal surface and reduce wear and friction.

3. Reliable. According to the inquiry enterprise investigation, Che David has a business license, is filed in the Administration for Industry and Commerce, and has legal protection, so Che David is reliable. The anti-wear protector of the car David engine has a certain effect.

4. The engine wear-resistant protective agent has a certain effect, but it is only temporary. A good protective agent is also relatively expensive, and the oil has a proportion. Adding additives at will may change the nature of the oil and affect the state of the engine. So it's better to change to a higher level of engine oil.

5. Che David engine wear-resistant protector is an additive that can be used to protect automobile engines. However, cars of different brands and models may addThe applicability of additives is different, so it is recommended to check the instructions of the car or consult the manufacturer or repair shop before use to ensure that the additive is suitable for your car.
