When choosing an engine oil, it involves a variety of performance statements, such as: wear resistance, cleanliness, fuel economy, acceleration, durability in harsh environments, high temperature resistance, adhesion of active ingredients, etc. Most of the performance is also literally understood. But some properties, such as: the adhesion of active ingredients is very brain-wrenching, what is the adhesion of active ingredients in motor oil?
1. What is the adhesion of active ingredients in engine oil?
The adhesion of the active ingredient of engine oil, in simple terms, is the stability of the oil film formed by the active ingredient in the engine on various parts inside the engine. The higher the stability of the oil film, the better the lubrication effect of the oil, and the more the performance of the engine can be fully utilized.
2. Why is adhesion important?
Protect the engine: A good quality oil can form a stable oil film on the metal surface of the engine, which plays a role in lubrication, friction reduction, cooling and cleaning. This film reduces direct contact between metals, reducing wear and tear to extend the life of the engine.
Improved power performance: The stable oil film can reduce frictional resistance and make the engine run more smoothly. This means that the vehicle's dynamics are improved, acceleration is smoother, and fuel consumption is reduced.
Reduce the risk of failure: The instability of the oil film may lead to local overheating of the engine, sludge accumulation and other problems, which in turn can lead to a series of failures. A stable oil film prevents these problems and reduces the cost of repairs and replacement parts.
3. What kind of engine oil has good adhesion?
When many engine oil products are promoted, they rarely mention the adhesion performance of the active ingredients of the engine oil, I don't know if it is because the oil film strength is insufficient, or because the adhesion performance is not important. However, I believe that the oil products that dare to hype up the adhesion performance of the engine oil must not have a bad oil film strength. For example: Idemitsu IFG series 0W-20 low viscosity fully synthetic motor oil:
This fully synthetic engine oil, which has the title of "low viscosity expert" in the lubricant market, has been recognized by most car owners for its good performance in environmental protection, anti-low-speed pre-ignition, chain protection, etc.
Some car owners said: "Do not use oil with too low viscosity, low viscosity oil film strength is not enough, easy to cause engine wear". However, from my use of Idemitsu IFG series low-viscosity engine oil products, I do not feel that Idemitsu low-viscosity engine oil has poor adhesion or insufficient oil film strength. Including the main sales markets of Idemitsu low-viscosity fully synthetic engine oil, there are no car owners in Japan and South Korea who have reported that "Idemitsu low-viscosity fully synthetic engine oil, insufficient oil film strength".
Therefore, it is not that the strength of the oil film of low-viscosity engine oil is insufficient, but mainly between different brands, the quality of engine oil is high and low.
It is recommended that car owners do not choose low-quality engine oil in pursuit of short-term savings, as this may lead to engine failure and more maintenance costs. Choosing a high-quality engine oil and following the manufacturer's recommended maintenance schedule is the only way to take responsibility for your car.
