Dispersants are additives used in lubricants to keep contaminants such as soot, dirt, and wear particles suspended in the oil. This prevents the particles from clumping together and forming sludge or sediment, which could cause engine damage or reduce the effectiveness of the lubricant. Dispersants help in extending the life of the oil and machinery by maintaining the cleanliness of internal parts. They are particularly effective in high-speed engines, diesel engines, and machinery operating under high-stress conditions. Their key advantage lies in improving the lubricant's ability to resist degradation and breakdown, which enhances performance and protects critical engine components. Dispersants are widely used in automotive oils, heavy-duty engine oils, and industrial lubricants.
