How about the anti-wear protector of the car David engine

1. Useful. According to the query, the anti-wear protector of the car David engine is really useful.

2. Useful Che David anti-wear protector is useful, because Che David anti-wear protector is of reliable quality, and the wear-resistant effect is obviously very cost-effective, and the reputation is very good.

3. Car David engine wear-resistant protector is an additive that can be used to protect automobile engines. However, different brands and models of cars may have different applicability to additives, 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.

4. 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.

5. 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 ratio. 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.

How often should the engine protector be used?

Engine protection agent is used about once for 15,000-20,000 kilometers, usually used with cleaning agent. Its main function is to protect the engine, greatly reduce wear, improve engine power and fuel economy, and prevent carbon generation.

Generally, an engine protector is used once for a car to drive 15,000 to 20,000 kilometers. Because the protective agent on the engine has been consumed during this period of mileage, it is easy to cause engine wear if the engine protective agent is not used. Engine protectors are usually used together with cleaners.

ButThere is no need to add it every time it is maintained. Engine protector can be added every 10,000 kilometers, and the cleaning agent can be used once every 20,000 kilometers. However, for vehicles with poor road conditions, such as poor air quality in the place of use and very congested road conditions, in this case, the engine is finally cleaned during each maintenance.

km. The car turbocharged is maintained once every 7,500 kilometers. The working principle of the turbocharged engine is to use the exhaust gas generated by the engine during the working process to drive the turbine to move.

● The vehicle is used once per 5,000-8,000 kilometers.

Is it necessary to add engine protector during maintenance?

Because of this, the engine protector is very practical. If the engine of the vehicle is well maintained and the lubricating oil applied is of high quality, in fact, the engine protector is not so necessary. However, if stronger maintenance of the engine is needed, it is also necessary.

The engine protector can form a long-term protective film on the metal surface, and it will not be deposited into the oil span with the lubricating oil.In this way, the moment of cold start can protect the engine and reduce wear.

That's why the engine protection agent is very practical. If the engine of the usual vehicle is well maintained and the lubricating oil used is of high quality, in fact, the engine protection agent is not so necessary. However, if stronger maintenance of the engine is needed, it is also necessary.

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.
