Engine oil is the key to engine maintenance, and dispersants are indispensable additives in engine oil. So, why add dispersants to engine oil? Let’s explore it below.
Dispersants are actually added to engine oil to prevent the build-up of sludge and varnish deposits. Over time, as engine oil ages, it breaks down and forms sludge, a sticky substance that clogs oil passages and makes your engine less efficient. Dispersants are additives that help break down and disperse sludge, preventing it from building up and causing damage. They prevent the build-up of harmful deposits, keeping your engine clean and ensuring proper lubrication.
Engine oil is a kind of lubricating oil. Its main function is to form a protective film on the friction surface inside the engine to reduce wear, reduce friction resistance and save energy. However, as the engine running time increases, some impurities and tiny particles will gradually appear in the oil. If these substances are not removed in time, they will cause damage to the engine.
At this time, dispersants play an important role. Dispersants are surfactants that have the ability to disperse, suspend, and stabilize impurities and tiny particles in engine oil. It can wrap up impurities and tiny particles so that they do not settle at the bottom of the oil, but are evenly dispersed in the oil.
In addition, dispersants also have friction-reducing and anti-wear effects. It can be adsorbed on the metal surface to form a protective film, reducing friction and wear inside the engine and improving the engine’s working efficiency and service life. At the same time, dispersants can also prevent the formation of carbon deposits and keep the interior of the engine clean.
In short, the purpose of adding dispersants to engine oil is to improve the cleanliness and dispersion of the engine oil, so that impurities and tiny particles in the engine oil are suspended in the engine oil, avoiding settling at the bottom, and keeping the interior of the engine clean and operating normally. In addition, dispersants can also reduce friction and anti-wear, improving engine efficiency and service life. Therefore, when choosing engine oil, you should choose an engine oil containing high-quality dispersants to ensure the normal operation of the engine and extend its service life.
