The reality is simple: machines don’t fail suddenly—oil fails quietly first.
Hydraulic, turbine, and lubrication oils can look normal and still be heavily contaminated. Microscopic particles, moisture, and oxidation by-products are invisible to the naked eye but extremely destructive to pumps, valves, bearings, and seals. By the time performance drops or noise appears, internal damage is often already done.
In fact, studies show that up to 80% of hydraulic failures are contamination-related, not mechanical. Dirty oil accelerates wear, increases operating temperature, disrupts lubrication films, and shortens component life while the machine may continue running “normally” for weeks or months.
Another misconception is that topping up with fresh oil fixes the issue. In reality, adding new oil to contaminated oil only dilutes the problem temporarily. Without proper filtration, contaminants continue circulating, damaging critical components every minute the machine operates.
Modern maintenance strategies focus on oil condition, not just machine condition. Parameters like ISO cleanliness levels, moisture content (ppm), and oxidation indicators provide early warnings long before failures occur. Advanced filtration systems—such as depth filtration and vacuum dehydration—remove contaminants and restore oil health while the machine stays operational.
