There are many negative effects to having contaminants in the lubricant. Sometimes they can lead to catastrophic failure. Dispersants help to keep contaminants in suspension.

Dispersants function by stabilizing colloidal dispersions and preventing them from agglomerating and coming out of oil as particulates and dirt.

They are critically important in helping to keep parts clean and in maintaining proper oil flow throughout the engine.

Wuxi South Petroleum Additives offers a number of high quality dispersants for various engine oil applications.
