Oil issues
Oil Additive Depletion
Oil additives support lubrication, protection and pressure stability in the hydraulic system. Over time, these properties are gradually consumed during normal operation. When additive levels drop too far, oil performance can change without obvious visual signs.
Understanding the Problem
Why do additives deplete over time?
Additives are designed to react under load, temperature and mechanical stress. As they perform their function, their concentration in the oil is reduced. If depletion is not identified in time, the oil may no longer support stable lubrication and system behaviour.
Typical symptoms
Oil analysis indicates reduced additive levels
Laboratory results show depletion compared to expected ranges.
Changes in lubrication performance
Friction behaviour begins to deviate under load.
Accelerated wear trends
Wear indicators increase without a clear mechanical root cause.
Shortened oil service intervals
Oil reaches performance limits earlier than anticipated.
Less stable hydraulic behaviour
Small deviations appear in pressure or response consistency.
Solution
Re‑additivation
Re‑additivation restores oil performance by replenishing depleted additive packages. This allows the existing oil to regain its intended protective and lubricating properties. By correcting additive balance, oil life can be extended while maintaining stable hydraulic behaviour. The focus is preserving oil functionality and avoiding unnecessary oil replacement.
