Viscosity modifier is an additive used in lubricants and greases to change their viscosity, or thickness. It is also known as a thickener. Viscosity modifiers are added to oils to make them thicker, which can improve the performance of the lubricant, especially under high-temperature or heavy-load conditions.
There are two main types of viscosity modifiers: polymeric and non-polymeric.
Polymeric viscosity modifiers are usually made from long-chain molecules, such as polymers. They work by entangling with the oil molecules, which makes the oil thicker.
Non-polymeric viscosity modifiers are typically made from shorter-chain molecules, such as waxes. They work by increasing the space between the oil molecules, which also makes the oil thicker. Viscosity modifiers are used in a variety of lubricants, including motor oils, gear oils, hydraulic oils, and greases.
They can improve the performance of these lubricants by making them thicker, which can help to reduce wear, prevent leaks, and protect against corrosion. Viscosity modifiers can also help to improve the efficiency of lubricants by reducing friction and making them flow more easily. There are a number of different types of viscosity modifier, each with their own advantages and disadvantages.
The type of viscosity modifier that is best suited to a particular application will depend on a number of factors, including the operating conditions, the type of lubricant, and the desired properties of the lubricant. Viscosity modifiers are available in a variety of formulations, and can be custom-blended to meet the specific needs of an application. There are a number of companies that offer viscosity modifier products, and it is important to select a reputable supplier that can provide a high-quality product.
What is Engine oil viscosity modifiers
- Gasoline engine oil viscosity modifier maintains the quality of engine oil with additional additives that stabilize viscosity, reduce wear and reduce the intensity of oxidation processes.
- Engine oil viscosity modifier for gasoline engines provides additional protection against engine overheating and allows the engine oil to maintain its key properties longer to maintain optimum engine performance until the next oil change.

Frequently Asked Questions (FAQ)
Two main types of modifiers are used in engine oil: detergents and dispersants. Detergents are compounds that help clean the engine by removing deposits from vital components and preventing further buildup. Dispersants, on the other hand, prevent sludge and other contaminants from sticking to engine parts by keeping them suspended in the oil until they can be drained out during an oil change. Both of these modifiers help protect against wear, corrosion, and thermal breakdown, extending engine life and improving performance. It is important to use the right type of additive package for your vehicle since different engines require different levels of protection. By using high quality motor oils with properly balanced additives, you can ensure that your engine runs smoothly and efficiently for years to come.
Viscosity modifiers are an important part of car engine lubrication. In essence, viscosity modifiers work by changing the properties of the oil and allowing it to flow more freely in colder temperatures. They also reduce friction between moving parts, which helps to reduce wear and tear on components over time.
