Lubricant Analysis
An integrated lubricant management system.
What began as a brief to draft sample commentary became Viscorai™, a connected lubricant management system. Sampling, laboratory interpretation, technical support, maintenance and commercial follow-up share one record from the sample to the action it generates.

Reliability engineers, lubricant suppliers, oil-analysis laboratories and technical-service teams.
Why the work matters.
Used oil analysis is increasingly central to condition-based maintenance, while experienced analysts are retiring and commentary varies between specialists. Separate sample, laboratory and customer records make it difficult to turn an interpretation into timely action.
What we developed.
Drawing on first-hand experience as oil-analysis end users, Propel expanded a commentary task into a complete lubricant service. The system connects the data, engineering rules, cited AI answers, oversight and apps needed by field staff, laboratories, customers and supplier teams.
Follow the operational thread.
Connect the information, apply the relevant checks and make the next decision visible.
Connect the sample and its journey
QR-enabled mobile capture ties each sample to its equipment and sampling point, with notes, photos and courier history. A laboratory-receipt scan can trigger pre-agreed charges, with the sample record as proof.
Interpret with evidence and oversight
Engineering rules assess readings, limits and trends. AI drafts commentary with sources and confidence scores. Suppliers choose autonomous issue, review by exception or full supervision to suit the service.
Close the loop with the customer
Technical answers cite a verified library by document, section and page. Specialist corrections are peer-reviewed; recurring adverse results can become cases, and accepted reports can feed maintenance work orders.
Connect technical service and follow-up
Sampling coverage, recurring issues and customer history identify service needs and relevant commercial opportunities. Commercial rules read the technical findings without changing the diagnosis.
Different roles.
The same evidence.
Dashboards, timelines and work queues make the relevant information available before someone has to ask a question.
Field and logistics
Equipment, sampling points, overdue samples and kit status.
Engineering and customers
Equipment trends, cited commentary, technical answers and owned cases.
Supplier and service teams
Fleet and lubricant insight, anonymised benchmarking and unresolved service needs.
What the user can inspect
- Measurements, units, methods and equipment history
- Applied engineering rules and cited technical guidance
- Oversight setting, review history and the follow-up action
What this is designed
to improve.
- Earlier intervention and lubricant changes based on equipment condition
- Faster, consistent commentary and referenced technical answers
- Specialists freed for difficult cases and services such as system flushing
- Fleet and lubricant benchmarking to support service and product improvement
- Less billing administration through charges tied to laboratory receipt
- A permanent sample and decision history for customer care, audits and warranty support
Evaluate the complete sample-to-action workflow: handling and review time, citation quality, sampling coverage and completion of follow-up actions.
Viscorai™ is live and commercially available. The customer is anonymised.
