Ashless dispersants used in lubricant

dispersing contaminants and byproducts of combustion that can accumulate in the oil.

These dispersants function by keeping insoluble particles suspended in the oil, preventing them from clumping together and forming deposits on engine or machinery surfaces. They help

maintain the cleanliness of the engine or machinery by allowing the contaminants to be removed during oil changes or filtration processes.

The term “ashless” refers to the absence of metallic elements such as calcium, magnesium, or barium that are present in traditional detergent additives. Ashless dispersants are often preferred

in applications where the presence of these metallic ash-forming elements could be detrimental, such as in certain emission control systems or in engines where catalysts are employed.

These additives are crucial for maintaining the performance and longevity of engines and machinery by ensuring that harmful deposits don’t build up and impede their operation.
