Used oil analysis intelligence that drafts expert-grade commentary in seconds, answers technical questions from your own verified library, and shows its working on every single answer.
Viscorai is deterministic AI-powered used oil analysis (UOA) software from The Propel Group. It drafts expert-grade oil analysis commentary, answers lubricant and equipment questions from your verified technical library, and cites its source on every answer, under as much or as little human oversight as you choose.
Maintenance is moving away from fixed, time-based servicing towards condition-based and predictive models. In that world, used oil analysis is no longer a routine formality. It becomes a primary input into the decision that decides whether to intervene, how urgently, and how far to go. A vague, hedged or inconsistent write-up can mean a missed early warning, or an intervention that was never needed.
At the same time, the people who turn those results into sound judgements are getting harder to find. The engineers and maintenance leads who read a report, infer the condition of the lubricant and the equipment, and make the call on timing and scope are retiring faster than they are being replaced. Knowledge retention is a recognised, systemic challenge across operators, and a particularly sharp one in the energy sector, driven by cost pressure, an ageing workforce, and difficulty attracting new talent in.
So the gap widens from both directions: each sample is asked to carry more, while the expertise to interpret it well and consistently is in shorter supply.
As maintenance shifts to condition-based and predictive models, oil analysis becomes a direct input to the intervention decision. Weak or inconsistent commentary now carries a real operational cost.
Two analysts, one sample, two different write-ups. When that commentary drives a maintenance call, the variation is not cosmetic. It changes what gets done.
The engineers who interpret reports and judge when to act are retiring faster than they can be replaced. Decades of pattern recognition leave with the person, and little of it is captured.
Your analysts' judgement, at machine speed.
Viscorai reads every incoming sample against the asset's history, the oil's specification, and your organisation's own technical guidance, then drafts the commentary your analyst would have written. Red, amber or green, with the reasoning attached. Your expert reviews and approves, or, once you trust it, lets Viscorai issue routine commentary on its own. You set the level of oversight.
"What's the wear-metal limit for this engine family?" "Can these two oils be mixed?" Viscorai answers from your verified document library: product data sheets, OEM guidance, your own procedures. It cites the document, section and page for every claim. Limits and specifications are quoted word for word, with units and test method. Never paraphrased, never rounded.
Dashboards that turn thousands of individual results into fleet-level insight: which assets are trending toward trouble, which sites are sampling on time, how your equipment compares against anonymised peers running similar duty.
Every sample tracked through its full chain of custody: scanned at the point of draw, matched to the right asset automatically, visible at every step. No more mystery bottles, no more results filed against the wrong equipment.
AI that says "I don't know" is AI you can put in front of a customer. Most AI tools are confident about everything, including the things they've made up. Viscorai is built the other way round.
Every answer names the document, section and page it came from. No source, no answer.
Every answer carries a confidence rating, and the rating decides what happens next.
When the evidence isn't there, Viscorai refuses to guess and routes the question to your experts instead.
Every decision the system makes is recorded, permanently. When a customer asks "why did it say that?", there is always an answer.
Built to fit your operation, not the other way round.
Viscorai plugs into the systems you already run: lab results, equipment registers, document libraries, maintenance systems. Your data stays yours, isolated and secure.
Every sample and every question is assessed against your verified knowledge base and the asset's own history. Every response is cited and confidence-scored.
Decide how much human involvement each response needs, separately for routine commentary and technical answers.
Viscorai issues commentary and technical responses automatically, with no human step, where you want speed and scale.
Responses that clear your confidence threshold are issued automatically; anything that falls short is held for an expert to review. You set the threshold.
Every response is reviewed and approved by your team before it is issued.
Whichever mode you choose, every response stays cited, confidence-scored and permanently audited, so you can move the dial towards autonomy as your trust in the system grows.
A single oil sample is a data point. A million of them, structured and connected, form a comprehensive picture of lubricant and equipment performance.
Viscorai is built as a platform: every analysed sample enriches the intelligence available to every fleet on it, anonymised, aggregated, and consent-controlled. Your competitors never see your data. But your engines benefit from patterns learned across every engine like them.
Turn your oil analysis programme from a cost centre into the stickiest product you sell.
Ship expert-grade commentary at volume, with consistency your customers can measure.
Energy, marine, power, mining, manufacturing: class-leading lubricant and equipment condition insights, the knowledge of a senior lubricant application engineer at your fingertips, and the confidence to optimise your maintenance programme.
Viscorai wasn't built by a software team who discovered lubrication last quarter. It was built by The Propel Group: engineers who have run lubrication programmes on rotating equipment, sat with the analysts, and lived with the consequences of a missed red flag.
More about The Propel Group →Viscorai is a class-leading product from The Propel Group, the same team that has run lubrication and reliability programmes in the field. Value-led digital transformation underpinned by the strategy and operational change to make it stick.
Viscorai is deterministic, AI-powered used oil analysis (UOA) software from The Propel Group. It drafts expert-grade oil analysis commentary, answers lubricant and equipment questions from a verified technical library, and cites its source on every answer.
Used oil analysis (UOA) is the laboratory testing of an in-service oil sample to judge the condition of both the oil and the equipment it came from. It measures wear metals, contamination, and the oil's physical and chemical properties to spot developing faults before they cause a failure. Viscorai turns those lab results into clear, cited commentary.
No. Viscorai drafts the commentary and answers the questions, and you choose how much human oversight each response needs, from full expert sign-off, to review only where a response falls below your confidence threshold, to fully autonomous. It is built to take the routine load off your experts so their judgement is spent where it matters, not to remove them from the decision.
Yes, if you want it to. Viscorai can issue commentary and technical responses fully autonomously, or hold back only those that fall below a confidence threshold you set, or route every response through your team for approval. The level of supervision is entirely at your discretion, and every response stays cited, confidence-scored and audited whichever mode you choose.
Every answer names the document, section and page it came from, carries a confidence rating, and is recorded permanently for audit. When the evidence isn't there, Viscorai declines to guess and routes the question to a human expert instead. Limits and specifications are quoted word for word, never paraphrased.
Viscorai connects to the systems you already run: laboratory results, equipment registers, technical document libraries and maintenance systems. Your data stays isolated, secure and yours, and is never shared with competitors.
Viscorai is built for lubricant suppliers, oil testing laboratories, and fleet and plant operators across sectors such as energy, marine, power, mining and manufacturing.
Viscorai is built by The Propel Group, a team of engineers who have run lubrication programmes on rotating equipment and deliver strategy, software and operational change together.
The fastest way to understand Viscorai is to watch it work on a real sample. Thirty minutes, your data or ours.
