The Challenge

OptiGas (NEF Förderungs GmbH) together with Spectrolytic challenged the norm and in collaboration have delivered remarkable results in oil life extension in real world conditions.

A biogas engine operator was changing oil every 600 hours based on a fixed, conservative schedule. There was no visibility into actual oil condition — resulting in:

The operator required a reliable method to validate extended oil use without compromising equipment reliability.

The Solution

A Spectrolytic FluidInspectIR® Plus system was installed to provide continuous, real-time oil condition monitoring. The system tracked key parameters including TAN, TBN, oxidation, sulphation, water etc. using mid-IR based chemical analysis — delivering actionable data on degradation, contamination, and additive performance.

This enabled a shift toward evidence-based maintenance decision-making.

Implementation

Results

The deployment delivered clear, measurable outcomes:

Operational Impact

Key Insight

FluidInspectIR® provided the actionable data validation required to safely challenge OEM-defined intervals. Rather than relying on conservative estimates, the operator could make decisions based on actual oil condition in real time.

Financial Benefits

Programme savings to date: > £10,000

Projected lifetime savings: > £100,000s

Conclusion

Spectrolytic FluidInspectIR® enables operators to move beyond fixed maintenance schedules and unlock the full functional life of their lubricants.

The result is a measurable combination of cost reduction, operational efficiency, and improved asset reliability — supported by real, actionable data.

When every litre counts, extending oil life is no longer just a maintenance improvement — it is a strategic supply chain advantage.

Organisations adopting advanced monitoring solutions such as Spectrolytic FluidInspectIR® today will be best positioned to manage volatility and optimise performance tomorrow.
