Oil Contamination

Oil contamination is one of the leading causes of premature engine and hydraulic system wear. Soot, fuel, water, coolant, dirt, wear metals and other contaminants gradually reduce lubrication performance, accelerate oil degradation and shorten equipment life.

This section of the Filter Solutions Ltd Engineering Knowledge Centre explains the most common forms of oil contamination, how they develop, the damage they cause and how engineers can detect and control them. You'll learn why maintaining clean oil is fundamental to reliable operation, longer oil drain intervals and condition-based maintenance.

Whether you're responsible for diesel generators, hydraulic systems, marine engines, CHP plants or industrial machinery, these articles provide practical guidance on contamination control, oil analysis, high-efficiency filtration and real-time oil condition monitoring to maximise equipment reliability and reduce maintenance costs.
