What Khash Learned Through Noria Machinery Lubrication Engineer Training and MLE Certification
From Lubrication Knowledge to Lubrication Engineering
Completing Noria’s Machinery Lubrication Engineer training and later achieving the ICML Machinery Lubrication Engineer — MLE certification changed my view of lubrication completely.
Before this journey, lubrication could easily be seen as a technical activity: selecting oil, selecting grease, taking samples, checking ISO cleanliness, changing filters, and reacting to failures. After going through the MLE body of knowledge, it becomes very clear that lubrication is not only a maintenance task. It is an engineering discipline connected to asset management, reliability, energy efficiency, risk control, financial performance, safety, sustainability, and long-term equipment life.
For me, the biggest lesson is this:
Lubrication excellence is not about oil. It is about engineering decisions that protect machines, reduce risk, improve reliability, and convert lubrication knowledge into measurable business value.
1. Lubrication Must Be Connected to Asset Management
One of the strongest messages from the MLE training is that lubrication must not be isolated from the asset management system.
A lubricant is not simply a consumable. In critical rotating machinery, the lubricant is part of the asset’s health system. It transfers load, removes heat, controls friction, prevents wear, protects against corrosion, carries contamination, and gives us diagnostic information through oil analysis.
This means that lubrication decisions should be aligned with:
- asset criticality,
- production risk,
- safety risk,
- environmental risk,
- maintenance cost,
- reliability objectives,
- energy consumption,
- life-cycle cost,
- and return on net assets.
The MLE mindset teaches that lubrication must be managed through a structured system, not through random habits or supplier preference. For example, choosing a turbine oil, hydraulic oil, compressor oil, or grease should not be based only on price or brand. It should be based on machine design, operating environment, failure modes, lubricant chemistry, OEM requirements, contamination risks, drain interval strategy, and monitoring capability.
This is where lubrication becomes part of ISO 55000-style asset management thinking. The question is no longer only, “Which oil should I use?” The better question is:
Which lubrication strategy gives the lowest total risk and best life-cycle value for this asset?
2. Lubrication Excellence Requires a Complete System, Not One Good Product
Another major lesson is that no single oil, grease, filter, additive, sampling bottle, or analysis test can create lubrication excellence alone.
Lubrication excellence is built from a complete system:
- correct lubricant selection,
- correct lubricant storage,
- correct transfer and handling,
- correct application method,
- correct contamination control,
- correct sampling method,
- correct oil analysis test slate,
- correct interpretation,
- correct action limits,
- correct work processes,
- correct training,
- correct ownership,
- and continuous improvement.
In the real world, many plants have good lubricants but poor storage. Some have good oil analysis but poor sampling. Some have good filtration but poor breathers. Some have expensive lubricants but no contamination control. Some have many reports but no action.
MLE training makes one point very clear:
A lubrication program fails at its weakest interface.
For example, a world-class turbine oil can still fail early if it is exposed to water, air entrainment, high temperature, wrong top-up oil, poor reservoir design, depleted antioxidants, varnish precursors, or poor filtration philosophy. A premium grease can still destroy a motor bearing if the relubrication quantity is wrong, the interval is wrong, or the application method pushes grease into the windings.
The real job of a lubrication engineer is to design and control the whole lubrication ecosystem.
3. Oil Analysis Is Not a Report — It Is a Decision-Making Tool
Before advanced lubrication engineering training, many people see oil analysis as a laboratory activity. A sample is taken, a report comes back, and someone checks whether the result is green, yellow, or red.
The MLE view is much deeper.
Oil analysis is a reliability decision tool. It must answer practical questions:
- Is the lubricant still fit for service?
- Is the machine generating wear?
- Is the oil contaminated?
- Is oxidation starting?
- Are additives depleting?
- Is varnish potential increasing?
- Is water entering the system?
- Is the lubricant compatible with the machine and previous oil?
- Is the current maintenance strategy working?
- What action should be taken now?
- How much time do we have before functional failure?
This is very important for turbine oils. A turbine oil may look clean and bright, but still have high varnish potential. It may have a normal acid number but declining antioxidant reserve. It may have acceptable particle count but dissolved degradation products. It may have low water content at the time of sampling but repeated water ingress history.
For me, MLE reinforced that oil analysis must be interpreted as a system of evidence, not isolated numbers. TAN, RULER, MPC, RPVOT, FTIR, viscosity, water, particle count, demulsibility, air release, foam, elemental analysis, and visual inspection must be connected to the machine’s operating context.
A good lubrication engineer does not read oil analysis values. He reads the story behind the values.
4. Contamination Control Is One of the Highest-Return Reliability Activities
The training strongly reinforces that contamination control is not housekeeping. It is engineering.
Particles, water, air, heat, wrong lubricants, process chemicals, fuel dilution, coolant, and oxidation by-products all attack the lubricant and the machine. Contamination control should therefore be treated as a proactive reliability strategy.
For rotating equipment, contamination affects:
- bearing fatigue life,
- journal bearing film stability,
- hydraulic valve performance,
- servo valve reliability,
- gear tooth life,
- oil oxidation,
- additive depletion,
- varnish formation,
- corrosion risk,
- filter life,
- and energy consumption.
In turbine oil systems, contamination control becomes even more critical because the oil volume is large, the oil life target is long, and the cost of failure is very high. A turbine oil system should not be managed like a small gearbox. It needs a life-extension strategy.
This is why proper breathers, kidney-loop filtration, water removal, varnish mitigation, reservoir inspection, sampling discipline, and clean transfer methods are essential.
One of my personal conclusions is:
Oil cleanliness is not only about ISO 4406 codes. It is about controlling every contaminant that changes the lubricant’s ability to protect the machine.
5. Lubricant Selection Is an Engineering Specification, Not a Purchase Description
A very important learning point from Noria-style training is that lubricant selection should be documented as a specification.
A lubricant specification should include more than “ISO VG 46 turbine oil” or “EP2 grease.” It should define the physical, chemical, and performance requirements needed for the application.
For example, for turbine oils we may need to consider:
- viscosity grade,
- viscosity index,
- oxidation stability,
- RPVOT performance,
- TOST performance,
- demulsibility,
- air release,
- foam tendency and stability,
- rust and corrosion protection,
- compatibility with seals and paints,
- antioxidant chemistry,
- base oil type,
- varnish tendency,
- additive compatibility,
- OEM approval,
- and field service history.
For greases we need to look beyond NLGI grade. We must consider base oil viscosity, thickener type, dropping point, mechanical stability, oil separation, water resistance, pumpability, compatibility, load carrying capacity, oxidation stability, and relubrication method.
This is a powerful lesson:
Lubricant selection is not choosing a product. It is defining the engineering requirements of the machine and then matching the lubricant to those requirements.
6. Changing Lubricant Brands Is a Risk Management Activity
Many plants change lubricant brands because of cost, availability, tender results, or supplier agreements. The MLE mindset teaches that this is not a simple purchasing decision.
Changing brands can introduce compatibility risks:
- base oil incompatibility,
- additive interaction,
- seal compatibility issues,
- sludge formation,
- foam behavior change,
- demulsibility change,
- varnish behavior change,
- filterability problems,
- and unexpected deposit formation.
This is especially serious in turbine oils, hydraulic systems, compressors, and large circulating oil systems.
The lesson for me is that every lubricant changeover should have a written plan. It should include compatibility testing, flushing requirements, risk ranking, baseline oil analysis, supplier documentation, OEM consultation where needed, and post-change monitoring.
In other words:
A lubricant change is a small project, not a simple top-up activity.
7. Energy Efficiency Starts at the Lubricated Contact
One of the most interesting parts of the MLE training is the link between lubrication and energy conservation.
Many people think energy efficiency belongs only to electrical engineers, process engineers, or equipment designers. But lubrication has a direct role in friction, churning losses, pumping losses, boundary friction, mixed-film friction, and heat generation.
Wrong viscosity can increase energy losses. Too high viscosity can increase churning and pumping losses. Too low viscosity can reduce film thickness and increase metal-to-metal interaction. Over-greasing can increase temperature and energy consumption. Aerated oil can increase heat and reduce lubrication efficiency. Contaminated oil can increase friction and wear.
The message is simple:
Every unnecessary friction point is an energy leak.
For large plants, this becomes serious. Pumps, compressors, turbines, gearboxes, blowers, fans, hydraulic systems, and electric motors all consume energy. Lubrication quality affects the mechanical efficiency of these assets.
This helped me connect lubrication with sustainability. Good lubrication reduces wear, reduces energy consumption, reduces oil disposal, reduces spare parts consumption, reduces unplanned shutdowns, and improves environmental performance.
8. Reliability-Centered Lubrication Requires Failure Mode Thinking
A strong lubrication engineer must understand failure modes.
Lubrication tasks should not be created because “we always did it this way.” They should be connected to failure mechanisms.
For example:
- If the failure mode is abrasive wear, the control strategy is filtration, exclusion, and clean handling.
- If the failure mode is water-induced corrosion, the control strategy is water exclusion, dehydration, demulsibility monitoring, and reservoir inspection.
- If the failure mode is varnish-related servo valve sticking, the control strategy must address soluble degradation products, oxidation control, thermal stress, antioxidant health, and varnish potential.
- If the failure mode is grease over-lubrication, the control strategy is calculated grease quantity, correct interval, ultrasound-assisted relubrication, and proper technician training.
- If the failure mode is wrong oil top-up, the control strategy is lubricant identification, tagging, storage control, transfer equipment control, and training.
MLE training connects lubrication to RCM thinking. Every lubrication task should have a reason. Every test should support a decision. Every inspection should detect a failure mechanism early enough to act.
Lubrication excellence is not doing more tasks. It is doing the right tasks for the right failure modes.
9. Varnish Is Not Only a Filtration Problem — It Is a Chemistry, Temperature, and Solubility Problem
For me, as someone deeply involved in turbine oil reliability, one of the most valuable outcomes of advanced lubrication training is how it strengthens the chemical understanding of oil degradation.
Varnish should not be simplified as “dirty oil.” It is a complex result of oxidation, thermal degradation, additive depletion, solubility limits, temperature gradients, base oil polarity, electrostatic discharge, microdieseling, contaminants, and oil formulation behavior.
The most dangerous varnish precursors may remain dissolved in hot oil. They may not appear as particles in a standard particle count. They may plate out in cooler areas, servo valves, bearing housings, reservoirs, and low-flow zones. This is why MPC, RULER, TAN, FTIR, visual inspection, and operating history must be interpreted together.
The MLE mindset supports a broader view:
- Do not only remove what is already insoluble.
- Understand why the oil is degrading.
- Understand where deposits are forming.
- Understand the role of temperature and solubility.
- Understand additive depletion.
- Understand the effect of base oil chemistry.
- Understand the relationship between varnish potential and machine symptoms.
This is exactly why turbine oil reliability must be managed proactively. Waiting for servo valve sticking, bearing temperature issues, or deposits in the tank is already late.
Varnish control is not cosmetic oil cleaning. It is chemical reliability management.
10. Lubricant Storage and Handling Can Destroy Reliability Before the Oil Reaches the Machine
Another practical lesson is that lubricants can be damaged before they enter the equipment.
Poor storage and handling can introduce:
- water,
- dust,
- wrong oil mixing,
- degraded drums,
- dirty transfer containers,
- unfiltered top-up oil,
- open funnels,
- poor labeling,
- and uncontrolled dispensing.
This is one of the simplest areas to improve, but also one of the most commonly neglected.
A proper lubrication program needs:
- controlled lubricant storage room,
- clear lubricant identification,
- color coding,
- dedicated transfer containers,
- filtration during transfer,
- desiccant breathers on storage tanks,
- first-in/first-out stock rotation,
- shelf-life control,
- spill control,
- and trained technicians.
The powerful point is this:
A plant cannot achieve world-class lubrication with workshop-level oil handling habits.
11. Lubrication Must Be Measured With Metrics
MLE training also reinforces the importance of performance metrics.
A lubrication program cannot be managed by opinion. It needs measurable indicators such as:
- lubricant consumption,
- oil cleanliness compliance,
- water contamination events,
- percentage of machines with correct breathers,
- percentage of correct lubrication PM completion,
- number of wrong-lubricant events,
- number of lubricant-related failures,
- oil analysis alarm closure time,
- filtration performance,
- varnish potential trend,
- antioxidant depletion trend,
- bearing temperature trend,
- mean time between lubrication-related failures,
- and cost avoidance.
For turbine oil systems, I would add:
- MPC trend,
- RULER antioxidant reserve trend,
- TAN trend,
- demulsibility trend,
- water trend,
- varnish-related trip history,
- servo valve issue frequency,
- filter element consumption,
- oil replacement avoidance,
- and total oil life extension.
This is where lubrication becomes visible to management.
What is not measured usually becomes invisible. What is invisible is rarely funded.
12. Training Is Not Optional — Human Error Is a Lubrication Failure Mode
Many lubrication failures are not caused by lack of products. They are caused by lack of knowledge.
Examples are everywhere:
- wrong grease quantity,
- wrong oil top-up,
- poor sampling location,
- sampling from dead legs,
- using transparent or dirty sample bottles,
- opening drums in dusty environments,
- ignoring breathers,
- mixing oils during shutdown,
- interpreting oil analysis by single values,
- changing oil based only on color,
- ignoring water contamination,
- and assuming new oil is clean.
MLE training strongly reinforces that people are part of the lubrication system. Technicians, planners, reliability engineers, purchasers, warehouse staff, contractors, supervisors, and managers all influence lubrication quality.
This is why training must be role-based. A technician needs practical task competence. A reliability engineer needs interpretation competence. A planner needs PM strategy competence. A purchaser needs specification competence. A manager needs value and risk competence.
Lubrication excellence is not achieved by one expert. It is achieved when the organization becomes competent.
13. Financial Analysis Is Essential for Selling Lubrication Improvements
A major lesson is that technical people must learn to speak the language of business.
Many lubrication improvements fail to get approval because they are presented only as technical recommendations. Management may not understand the value of better filtration, improved oil storage, desiccant breathers, offline filtration, varnish removal, or better oil analysis unless the financial impact is clear.
A strong lubrication business case should include:
- avoided downtime,
- avoided oil replacement,
- avoided bearing failures,
- avoided servo valve failures,
- reduced filter consumption,
- reduced waste oil disposal,
- reduced labor,
- improved energy efficiency,
- improved production availability,
- reduced safety exposure,
- and reduced environmental risk.
For turbine oil reliability, this is very powerful. Avoiding one forced outage, one oil replacement, or one varnish-related control issue can justify a complete lubrication improvement program.
My conclusion:
Lubrication engineers must calculate value, not only diagnose problems.
14. The MLE Mindset: From Technician to Strategist
The attached certification is not only a certificate. For me, it represents a shift in professional identity.
The MLE mindset combines:
- lubrication fundamentals,
- lubricant chemistry,
- machine design,
- oil analysis,
- contamination control,
- reliability engineering,
- asset management,
- financial justification,
- maintenance strategy,
- risk management,
- and program leadership.
This is different from being only an oil analyst, bearing specialist, filtration specialist, or lubricant salesperson. MLE requires connecting all these areas into one integrated view.
A Machinery Lubrication Engineer should be able to answer:
- What lubricant is required?
- Why is it required?
- How should it be stored?
- How should it be applied?
- How should it be monitored?
- What failure modes are expected?
- What tests should detect them?
- What alarms should be used?
- What actions should follow?
- What is the business value?
- How does this improve asset reliability?
That is the difference between lubrication activity and lubrication engineering.
15. What Khash Personally Learned
My personal learning from Noria training and MLE certification can be summarized in this way:
I learned that lubrication is not a small technical corner of maintenance. It is one of the most powerful reliability disciplines in industry.
I learned that turbine oil is not just oil in a tank. It is a chemical, mechanical, thermal, and diagnostic asset.
I learned that oil analysis is not a laboratory report. It is an early-warning system for asset risk.
I learned that varnish is not only a deposit. It is a symptom of lubricant stress, chemistry change, solubility behavior, and system conditions.
I learned that contamination control is not cleanliness decoration. It is life extension engineering.
I learned that lubricant selection is not procurement. It is specification engineering.
I learned that lubricant storage is not housekeeping. It is contamination prevention.
I learned that lubrication PMs are not routine tasks. They are risk controls.
I learned that training is not optional. It is how companies remove human-error failure modes.
I learned that financial analysis is not separate from lubrication. It is how lubrication improvements are approved.
And most importantly:
I learned that world-class lubrication is achieved when science, discipline, field experience, standards, and business value are connected together.
Final Message
Noria’s Machinery Lubrication Engineer training and the ICML MLE certification helped convert many years of field experience into a structured engineering framework.
For me, it confirmed what I have seen in power plants, oil and gas facilities, petrochemical plants, steel plants, cement plants, and heavy industries:
Machines rarely fail only because of oil. They fail because the lubrication system around the oil is weak.
The oil may be wrong.
The storage may be wrong.
The sampling may be wrong.
The interpretation may be wrong.
The filtration may be wrong.
The PM may be wrong.
The training may be missing.
The management system may not exist.
MLE brings all of this together.
This is why I believe lubrication should be treated as a serious engineering discipline, not as a routine maintenance activity.
Lubrication is not about adding oil.
Lubrication is about protecting assets, controlling risk, extending life, reducing waste, and improving reliability.
That is what Khash learned from Noria training and the MLE journey.
