Introduction: Why I Started Looking at Lubricants Differently

Recently, I attended a daylong professional learning session on industrial lubrication. The session encouraged me to look beyond the conventional idea of lubricant as simply another maintenance consumable purchased by litre.

After the session, I studied the subject further from a technical procurement perspective. One important realization became clear to me:

“Lubricant is not simply a consumable purchased by litre; it is a reliability-critical engineering input that can influence the total operating cost of equipment.”

For a Procurement professional, this is an important shift in thinking. When comparing two lubricants, the question should not be only: “Which one has the lower price per litre?”

The better question is: “Which technically suitable lubricant can deliver the required equipment performance at the lowest justified Total Cost of Ownership?”

This article summarizes my learning and professional perspective on the subject, with particular focus on the intersection of Engineering, Maintenance, Procurement, Cost Management and Sustainability.

The Procurement Mindset

A lubricant purchase should ideally be evaluated through six questions:

• Is it the right lubricant?
• Is it suitable for the right application?
• Is the grade and performance appropriate?
• Is it coming from the right and reliable supplier?
• Does it provide an acceptable cost per operating hour?
• Can its performance be monitored and verified?

1. Why Should Procurement Care About Lubrication?

Lubrication is often viewed primarily as an Engineering or Maintenance responsibility. However, Procurement decisions directly influence lubricant quality, availability, authenticity, cost, supplier reliability and ultimately equipment lifecycle cost.

A lubricant can influence:

• Friction and wear
• Bearing, gear and component life
• Operating temperature
• Machine cleanliness
• Corrosion protection
• Energy consumption
• Maintenance frequency
• Oil change frequency
• Unplanned downtime
• Spare-parts consumption
• Production continuity
• Inventory requirements

Therefore, lubricant procurement should not be isolated from Engineering. The most effective approach is a joint decision between Maintenance/Engineering and Procurement.

2. Basic Lubricant Knowledge Every Procurement Professional Should Know

A Procurement professional does not need to become a lubrication engineer. However, understanding basic lubricant terminology helps Procurement ask the right questions and avoid making technically weak purchasing decisions.

Lubricating Oil vs Grease

Factor	Lubricating Oil	Grease
Physical form	Liquid	Semi-solid
Typical use	Engines, gearboxes, hydraulic systems, compressors, turbines and circulating systems	Bearings, joints, slow-moving or difficult-to-seal components
Heat dissipation	Generally better where continuous circulation is possible	More limited than circulating oil
Circulation	Can be pumped or circulated	Generally remains at the lubrication point
Sealing capability	Usually lower	Can help prevent contaminants entering the lubrication zone
Procurement consideration	Viscosity, performance specifications, OEM requirements and oil condition are critical	Base oil viscosity, thickener type, consistency, additive package and application suitability are important

Other common industrial lubricant categories include:

• Gear oils
• Hydraulic oils
• Compressor oils
• Turbine oils
• Engine oils
• Bearing oils
• Circulating oils
• Food-grade lubricants
• High-temperature and specialty lubricants

The important point for Procurement is that “lubricant” is not one generic product category. Different machines and components require different performance characteristics.

3. Mineral vs Synthetic Lubricant: Which One Should Procurement Buy?

This is one of the most common questions in lubricant procurement. The answer is not simply “synthetic is better.”

Mineral and synthetic lubricants can have different performance characteristics because their base oils and formulations differ. Synthetic lubricants can offer advantages in demanding applications, but the correct selection depends on equipment design, operating conditions, OEM requirements and economics.

Factor	Mineral-Based	Synthetic-Based	Procurement Interpretation
Purchase cost	Generally lower	Generally higher	Compare lifecycle cost rather than unit price alone
Temperature performance	Application dependent	Can perform well in demanding temperature conditions	Check actual application requirements
Oxidation resistance	Formulation dependent	Often advantageous in demanding applications	Potentially longer service life, but verify with technical data
Low-temperature performance	Application dependent	Can provide advantages in suitable formulations	Important for low-temperature applications
Service life	Depends on formulation and application	Can provide longer service intervals in suitable applications	Do not assume longer life without evidence
TCO	May be economical for suitable applications	Higher initial price may be justified by performance	Calculate cost per operating hour

Procurement Rule: Never select synthetic lubricant simply because it is “premium” and never reject it simply because it is expensive. First establish the technical requirement and then evaluate the economics.

4. Base Oil: Why Viscosity Alone Does Not Tell the Whole Story

Base oil is the primary fluid component of a lubricant formulation. The final lubricant, however, is normally a combination of base oil and performance additives.

At a high level, base oils can be classified into different groups according to their properties and refining or synthesis characteristics. For Procurement, the important lesson is:

Two lubricants can have the same viscosity grade but still provide different overall performance.

Therefore, when comparing technically equivalent products, Procurement should not stop at:

• Brand name
• Viscosity grade
• Price per litre

The comparison should also consider the lubricant's base oil, additive technology, performance standards, OEM approvals and application suitability.

5. Additives: The Performance Technology Inside the Lubricant

A lubricant's performance does not come only from its base oil. Additives are used to provide or improve specific performance characteristics.

Surface Protection Additives

• Extreme Pressure (EP) agents: Help protect surfaces under severe load conditions.
• Anti-wear additives: Help reduce component wear.
• Friction modifiers: Can reduce friction under suitable operating conditions.
• Corrosion inhibitors: Help protect metal surfaces from corrosion.
• Rust inhibitors: Help protect equipment from rust formation.

Fluid Property and Stability Additives

• Viscosity modifiers
• Pour-point depressants
• Antioxidants
• Thermal stability additives

Cleaning and Contamination-Control Additives

• Detergents
• Dispersants
• Anti-foam agents
• Demulsifiers where applicable

The important procurement lesson is that additive packages are application-specific. An additive package suitable for an engine may not be appropriate for a gearbox, hydraulic system or turbine.

6. Viscosity: One of the Most Important Properties Procurement Must Understand

Viscosity is the resistance of a fluid to flow. In lubrication, it strongly influences the lubricant's ability to maintain an appropriate lubricating film under operating conditions.

A common procurement mistake is to assume:

Higher viscosity = better lubricant.
This is not generally correct.

Likewise:

Lower viscosity = poor lubricant.
This is also not generally correct.

The correct viscosity depends on factors such as:

• Operating temperature
• Load
• Speed
• Component design
• Clearance
• Lubrication method
• OEM recommendation

Viscosity vs Viscosity Index

Viscosity describes how easily the lubricant flows at a specified condition.

Viscosity Index (VI) indicates how strongly viscosity changes with temperature. A higher VI generally indicates less viscosity change over temperature variation, although the actual suitability must still be evaluated against the application.

ISO VG and SAE Grades

Procurement professionals may encounter different grading systems such as ISO viscosity grades (ISO VG) and SAE grades. These systems serve different applications and should not be treated as interchangeable labels.

Always match the grade system and specification with the equipment requirement. Do not approve a lubricant merely because its number “looks similar.”

7. Lubricant Properties Procurement Should Compare

When reviewing technical offers, Procurement should understand the meaning of the major lubricant properties. However, remember that a higher numerical value is not automatically better for every property. The correct target depends on the application.

Property	What It Means	Why Procurement Should Care
Viscosity	Resistance of the fluid to flow	Must match operating conditions and OEM requirements
Viscosity Index	Indicates viscosity change with temperature	Important where operating temperature varies significantly
Flash Point	Temperature at which vapour can ignite under defined test conditions	Important for safety and handling; not the normal operating temperature
Pour Point	Lowest temperature at which the lubricant can flow under specified test conditions	Important for low-temperature applications
Oxidation Stability	Resistance to degradation caused by oxidation	Can influence lubricant life and deposit formation
Thermal Stability	Ability to withstand thermal stress	Important for high-temperature applications
Anti-Wear Performance	Ability to reduce wear under defined test conditions	Relevant to component protection
EP Performance	Protection under severe load conditions	Important for certain heavily loaded applications
Corrosion/Rust Protection	Protection against corrosion and rust	Important for equipment reliability and component life
Foaming Tendency	Propensity to form and retain foam	Excessive foam can interfere with lubrication and operation
Water Separation	Ability to separate water from oil where required	Important in systems exposed to moisture or water ingress
Filterability	Ability to pass through filtration systems appropriately	Important for systems relying on filtration

8. Flash Point vs Pour Point: Do Not Mix Them Up

Flash Point

Flash point is associated with the temperature at which vapour above a liquid can ignite under specified test conditions. It is relevant to lubricant handling and fire safety.

It should not be interpreted as the lubricant's maximum normal operating temperature. Actual operating limits depend on the lubricant formulation, equipment and application.

Pour Point

Pour point relates to low-temperature flow behaviour under a specified test method. It becomes particularly relevant where equipment operates or starts in low-temperature conditions.

For Procurement, the lesson is simple: do not compare properties without understanding why the property matters for the specific machine.

9. How to Select the Right Lubricant for a Specific Application

This is perhaps the most important practical section for Procurement. A lubricant should be selected based on the application first and the supplier second.

1

Identify the equipment.
Know the machine manufacturer, model and component.

2

Identify the lubrication point.
Engine, gearbox, bearing, hydraulic system, compressor, chain, etc.

3

Check the OEM recommendation.
Use the equipment manual and technical documentation as the starting point.

4

Understand operating conditions.
Check temperature, load, speed, environment and contamination exposure.

5

Determine required grade and performance.
Identify viscosity and required standards or approvals.

6

Evaluate technically suitable alternatives.
Compare products only after establishing technical acceptability.

7

Evaluate supplier authenticity and capability.
Confirm source, documentation, traceability and technical support.

8

Calculate TCO.
Compare cost per operating hour, not only purchase price.

9

Define monitoring.
Track consumption, oil condition, change frequency and equipment performance.

Right Lubricant Checklist

• Equipment identified
• Lubrication point identified
• OEM recommendation checked
• Required viscosity confirmed
• Required performance specification confirmed
• Operating temperature considered
• Load and speed considered
• Contamination/water exposure considered
• Lubrication method considered
• Alternative product technically approved
• Supplier authenticity verified
• TCO evaluated
• Monitoring plan established

10. OEM Recommendation: The Starting Point for Procurement

The OEM recommendation should normally be the starting point for lubricant selection. It helps establish the required viscosity, specification and performance characteristics.

If Procurement wants to introduce an alternative lubricant, it should not be approved simply because:

• The viscosity is the same
• The price is lower
• The supplier says it is “equivalent”
• The brand is well known

A proper alternative evaluation should consider:

• Base oil chemistry
• Performance specification
• Additive package
• OEM approval or technical suitability
• Operating conditions
• Compatibility
• Seal compatibility where relevant
• Existing lubricant condition
• Flushing requirements where necessary

Golden Rule: A lubricant substitution should be a technical decision supported by Engineering/Maintenance, not merely a commercial decision made because another product is cheaper.

11. Same Viscosity Does Not Mean Same Lubricant

Suppose two products both have the same nominal viscosity grade. It does not automatically mean that they can be freely mixed or substituted.

Their:

• Base oils
• Additive systems
• Performance standards
• Compatibility characteristics
• Seal compatibility
• Thermal/oxidation behaviour

may differ.

Therefore, when switching products, Procurement should request technical confirmation from the lubricant supplier and obtain Engineering/Maintenance approval. Where necessary, the equipment should be flushed according to the applicable technical procedure.

12. Lubricant Life: When Should Oil Be Changed?

Lubricant life depends on many variables:

• Operating temperature
• Load
• Operating hours
• Oxidation
• Water contamination
• Dust and dirt
• Metal particles
• Equipment condition
• Additive depletion
• Lubrication system design

Therefore, blindly changing lubricant only according to a calendar may not always be the most efficient approach. Where technically justified, condition-based monitoring and oil analysis can provide better information.

The objective should not be “change oil as late as possible.” The objective should be “use the lubricant for the appropriate service life without compromising equipment reliability.”

13. Oil Analysis: From “Change Oil” to “Understand Oil”

Oil analysis can provide valuable information about both lubricant condition and equipment condition.

Depending on the application and testing program, analysis may help identify:

• Lubricant degradation
• Contamination
• Water ingress
• Abnormal wear particles
• Viscosity changes
• Oxidation
• Additive depletion
• Potential equipment problems

This creates an important opportunity for Procurement. Instead of measuring lubricant consumption only in litres, Procurement can begin tracking:

• Litres per operating hour
• Cost per operating hour
• Oil change frequency
• Unplanned lubricant-related downtime
• Lubricant-related spare-part consumption

14. Top-Up Practice: What Procurement Should Understand

Large diesel engines and other high-volume lubrication systems may require periodic lubricant top-up. Maintaining the correct oil level is important, but topping up should not be treated as a replacement for proper maintenance.

Procurement and Maintenance should monitor lubricant consumption. Unexpectedly high consumption may indicate:

• Leakage
• Oil burning
• Seal problems
• Engine or component wear
• Operational problems

If a machine suddenly requires significantly more lubricant than its historical pattern, the issue should be investigated rather than simply increasing the purchase quantity.

15. The Hidden Cost of Cheap Lubricant

One of the most important lessons for Procurement is that the purchase price of lubricant represents only one part of the cost.

Direct Costs

• More frequent oil changes
• Higher lubricant consumption
• More filter replacements
• Additional maintenance materials
• Additional labour

Indirect Costs

• Machine downtime
• Increased component wear
• Bearing replacement
• Gear replacement
• Seal replacement
• Emergency maintenance
• Production interruption
• Potential energy losses

Strategic Costs

• Potential OEM warranty concerns
• Reduced equipment life
• Higher dependence on spare parts
• Emergency procurement
• Production delivery risk
• Business reputation risk

“Low purchase price ≠ low total cost.”

This is exactly why lubricant purchasing should be connected with Total Cost of Ownership.

16. Stop Looking Only at Cost per Litre: Think Cost per Operating Hour

Consider two technically suitable lubricants.

Parameter	Lubricant A	Lubricant B
Price	BDT 800/litre	BDT 1,200/litre
Oil capacity	100 litres	100 litres
Cost per oil fill	BDT 80,000	BDT 120,000
Example drain interval	2,000 hours	4,000 hours
Lubricant cost per operating hour*	BDT 40/hour	BDT 30/hour

*Hypothetical example for illustration only. Actual drain intervals must be based on OEM guidance, product specifications, operating conditions and condition monitoring.

Although Lubricant B has a higher purchase price per litre, its hypothetical cost per operating hour is lower.

However, the calculation should go further. Procurement should also consider:

• Filter cost
• Oil change labour
• Disposal cost
• Downtime
• Wear-related repair
• Spare parts
• Emergency maintenance
• Energy impact where measurable

17. Total Cost of Ownership (TCO) of Lubricants

A better lubricant procurement model considers the complete lifecycle cost rather than the invoice price alone.

Effective Lubrication Cost per Operating Hour =

(Lubricant + Filters + Labour + Oil Change + Disposal + Downtime + Expected Wear/Repair + Other Relevant Costs)

÷ Operating Hours

This is a conceptual framework. Actual calculations should use equipment-specific historical data wherever possible.

Potential TCO Components

TCO Element	Procurement Question
Purchase cost	What is the actual landed/received cost?
Logistics	What are transportation and delivery costs?
Storage	Does the product require special storage?
Oil change	How frequently does it require replacement?
Filter	Does lubricant condition influence filter consumption?
Labour	How much maintenance labour is required?
Downtime	Could lubricant-related problems stop production?
Wear/repair	Could poor lubrication increase component replacement?
Spare parts	Could increased wear raise spare-parts demand?
Disposal	What is the used-oil handling/disposal cost?
Sustainability	Can consumption, packaging and waste be reduced?

18. A Practical Technical-Commercial Lubricant Comparison Matrix

A good Commercial Comparison Sheet (CS) for lubricant procurement should not contain only price. A Procurement professional can use a structure like the following:

Parameter	Vendor A	Vendor B	Vendor C	OEM Requirement	Procurement Decision
Lubricant type	—	—	—	Required type	Technical screening
Base oil	—	—	—	Application dependent	Compare
Viscosity grade	—	—	—	OEM specified	Must comply
Viscosity Index	—	—	—	Application dependent	Compare
Flash Point	—	—	—	Application dependent	Review
Pour Point	—	—	—	Application dependent	Review
Performance standard	—	—	—	Required standard	Must comply
OEM approval	—	—	—	Required where applicable	Verify
Expected service life	—	—	—	Application dependent	TCO input
Unit price	—	—	—	Commercial	Compare
Supplier authenticity	—	—	—	Verified source	Critical
Lead time	—	—	—	Required availability	Compare
Technical support	—	—	—	Preferred	Evaluate
Oil analysis support	—	—	—	Where applicable	Evaluate
Estimated cost/hour	—	—	—	Lowest justified TCO	Calculate
Overall TCO	—	—	—	Lowest justified lifecycle cost	Final evaluation

19. Lubricant Buying Guideline from a Procurement Perspective

A practical lubricant procurement process can be divided into the following stages:

• Validate the user requirement.
• Identify the exact equipment and lubrication point.
• Collect the OEM recommendation.
• Define technical specifications clearly.
• Identify technically acceptable alternatives.
• Explore qualified suppliers.
• Verify supplier authenticity and source.
• Review TDS and SDS.
• Check COA/certification where applicable.
• Compare commercial offers.
• Calculate cost per operating hour.
• Evaluate TCO.
• Check availability and lead time.
• Evaluate technical support.
• Finalize supplier based on technical-commercial evaluation.
• Monitor supplier and lubricant performance after purchase.

20. How Procurement Can Reduce the Risk of Fake or Adulterated Lubricants

Counterfeit or adulterated lubricant can create a serious reliability risk because the product may not contain the expected base oil or additive formulation.

The resulting damage may be much greater than the initial purchasing saving.

Procurement Controls

• Buy through verified and authorized supply channels where possible.
• Conduct supplier due diligence.
• Verify the product's source and traceability.
• Check packaging and seals.
• Check batch or lot information.
• Review documentation.
• Verify TDS and SDS.
• Request COA where appropriate.
• Investigate unusual price deviations.
• Check storage and transportation practices.
• Use laboratory testing where risk justifies it.
• Use oil analysis when technically appropriate.

Potential Red Flags

• Unusually low price compared with the normal market range
• Inconsistent packaging
• Damaged or suspicious seals
• Missing traceability information
• Unclear product source
• Suspicious documentation
• Supplier unable to demonstrate product authenticity
• Inconsistent batch information

Important: Packaging inspection or visual inspection alone cannot guarantee lubricant authenticity. For higher-risk applications, supplier verification and appropriate technical testing may be necessary.

21. How to Evaluate a Lubricant Supplier

A lubricant supplier should be evaluated as a technical supply partner, not only as a source of products.

Evaluation Area	What Procurement Should Check
Technical capability	Can the supplier understand and support the application?
Authenticity	Can the supplier demonstrate a reliable source?
Availability	Is local or regional stock available?
Lead time	Can they support emergency and routine requirements?
Technical support	Can they support lubricant selection and troubleshooting?
Oil analysis	Can they support condition monitoring where applicable?
Documentation	TDS, SDS, COA and traceability available?
After-sales service	What support is available after delivery?
Training	Can they support user training?
Commercial reliability	Is pricing, supply and contractual performance reliable?

22. Storage and Handling: Even Good Lubricant Can Be Ruined

Procurement often focuses heavily on product selection and supplier selection. However, lubricant quality can also be affected by storage and handling.

Good practices include:

• Protect containers from moisture.
• Keep containers properly sealed.
• Protect lubricant from dust and contamination.
• Avoid unnecessary exposure to sunlight and extreme temperatures.
• Use clean dispensing equipment.
• Maintain proper labelling.
• Prevent cross-contamination between lubricant types.
• Apply appropriate stock rotation practices.
• Follow manufacturer storage recommendations.

Buying a high-quality lubricant at a premium price provides little value if the product is subsequently contaminated because of poor storage or handling.

23. Contamination: A Hidden Enemy of Lubrication

Common lubricant contaminants include:

• Dust
• Water
• Dirt
• Metal particles
• Wrong lubricant
• Cleaning chemicals
• Other oils or greases

Contamination control can involve:

• Clean storage
• Properly sealed containers
• Clean transfer equipment
• Appropriate filtration
• Desiccant breathers where applicable
• Proper oil sampling practices
• Dedicated dispensing equipment

24. Lubricant Procurement and Carbon Footprint

Lubricant procurement also has a sustainability dimension. Lubricant consumption creates environmental impact through different stages of its lifecycle, including:

• Raw material production
• Base oil production
• Additive production
• Packaging
• Transportation
• Storage
• Consumption
• Oil replacement
• Used-oil management and disposal

If a technically suitable lubricant can safely operate for a longer service interval, it may reduce lubricant consumption, packaging demand, transportation requirements, maintenance activity and used-oil generation.

But longer drain interval does not automatically mean greener lubrication. It should only be adopted where technically justified through OEM guidance, lubricant specifications, oil analysis and actual equipment condition.

25. Procurement and Engineering Must Work Together

Lubricant selection is one area where Procurement and Engineering should not work independently.

Engineering / Maintenance Should Provide

• Equipment information
• Application details
• OEM recommendations
• Operating temperature
• Load and speed
• Environmental conditions
• Technical acceptance criteria
• Failure history

Procurement Should Provide

• Supplier market intelligence
• Alternative sourcing
• Commercial comparison
• Negotiation
• Supplier qualification
• Availability and lead-time information
• TCO analysis
• Supply continuity strategy

Together They Can Develop

• Approved lubricant list
• Equivalent lubricant matrix
• Lubricant standardization strategy
• Supplier strategy
• Consumption dashboard
• Oil analysis program
• TCO monitoring

26. Why Procurement and Maintenance Should Learn Lubrication Together

The goal of joint training is not to make Procurement professionals into lubrication engineers. The goal is to create a common decision-making language.

Instead of asking, “Which lubricant is cheaper?”

Ask: “Which technically suitable lubricant delivers the lowest sustainable cost over the equipment lifecycle?”

A useful joint training program could include:

• Lubrication fundamentals
• Lubricant grades
• Base oils
• Additives
• Equipment lubrication requirements
• Common lubrication failures
• Oil analysis
• Counterfeit lubricant risks
• Supplier evaluation
• TCO calculation
• Sustainability

27. Common Lubricant Procurement Mistakes

1. Selecting only by price per litre.
2. Ignoring OEM recommendations.
3. Comparing only viscosity.
4. Assuming synthetic is always better.
5. Selecting only based on brand reputation.
6. Accepting “equivalent” claims without technical verification.
7. Mixing lubricants without compatibility assessment.
8. Buying from unverified suppliers.
9. Ignoring storage conditions.
10. Changing oil without considering actual condition where condition monitoring is appropriate.
11. Extending drain intervals without technical evidence.
12. Not tracking lubricant consumption.
13. Ignoring downtime in TCO.
14. Ignoring spare-part consumption.
15. Not involving Engineering in technical evaluation.
16. Treating lubricant as an ordinary consumable.

28. Key Takeaways for Procurement Professionals

• Do not evaluate lubricant only by BDT/litre.
• Start with the equipment and application, not the supplier.
• OEM recommendation should normally be the starting point.
• Same viscosity does not necessarily mean same performance.
• Synthetic is not automatically better for every application.
• Supplier authenticity is a reliability issue, not only a purchasing issue.
• Oil analysis can help convert lubricant management from reactive to condition-based.
• Cost per operating hour can be more meaningful than cost per litre.
• Downtime and spare-parts impact should be considered in lubricant TCO.
• The best procurement decision is the technically suitable option with the lowest justified lifecycle cost.

29. Conclusion: Lubricant Procurement Is More Than Buying Oil

Lubricant may look like a relatively small line item in a purchase order, but its impact can extend far beyond its invoice value.

The right lubricant can support equipment reliability, component protection, maintenance efficiency and production continuity. The wrong lubricant—or even a technically suitable lubricant purchased from an unreliable source—can create much larger downstream costs.

Therefore, Procurement should gradually move from:

“Which supplier is offering the lowest price?”

towards:

“Which technically suitable solution provides the lowest sustainable Total Cost of Ownership?”

This does not mean Procurement needs to become a Lubrication Engineer. Similarly, Maintenance does not need to become a Procurement Specialist.

But both functions need enough understanding of each other's priorities to make better decisions.

The ultimate objective is simple:

Right Lubricant + Right Application + Right Grade + Right Quantity + Right Interval + Right Supplier + Right Monitoring = Better Reliability + Better Cost Control + Better Procurement Decisions

For me, the biggest learning from studying industrial lubrication from a procurement perspective is that the value of lubricant should be measured by the equipment and business performance it supports—not simply by the price printed on the purchase quotation.

Frequently Asked Questions (FAQ)

1. Is the most expensive lubricant always the best lubricant?

No. The correct lubricant is the one that meets the technical and application requirements and provides the best justified lifecycle economics. A more expensive lubricant may offer advantages in some applications, but price alone does not determine performance.

2. Why should Procurement check the OEM lubricant recommendation?

The OEM recommendation provides an important starting point for viscosity, performance requirements and application suitability. It helps Engineering and Procurement establish the technical acceptance criteria before comparing suppliers.

3. Can two lubricants with the same viscosity be used interchangeably?

Not necessarily. Lubricants with the same viscosity can have different base oils, additive packages, performance specifications and compatibility characteristics. Any substitution should be technically evaluated before use.

4. Is synthetic lubricant always better than mineral lubricant?

No. Synthetic lubricants can provide advantages in certain demanding applications, but the correct choice depends on equipment design, operating conditions, OEM requirements, lubricant formulation and Total Cost of Ownership.

5. What is more important: lubricant price per litre or cost per operating hour?

For many industrial applications, cost per operating hour provides a more meaningful comparison because it considers service interval and lubricant consumption. However, a complete TCO evaluation should also consider filters, labour, downtime, repairs, spare parts and disposal.

6. How can Procurement identify counterfeit lubricant?

Procurement should use verified suppliers, establish product traceability, check packaging and batch information, review documentation and investigate unusual pricing. Visual inspection alone cannot guarantee authenticity; laboratory or technical verification may be appropriate for higher-risk applications.

7. Why is oil analysis important?

Oil analysis can provide information about lubricant degradation, contamination, wear particles and equipment condition. When appropriately implemented, it can support condition-based maintenance and help avoid unnecessary oil changes or identify developing problems.

8. Should lubricant always be changed after a fixed number of months?

Not necessarily. The appropriate interval depends on the equipment, lubricant, operating conditions and maintenance strategy. Where technically appropriate, oil analysis and condition monitoring can help determine lubricant condition and support optimized intervals.

9. What should Procurement check before buying industrial lubricant?

Procurement should check the equipment/application, OEM recommendation, viscosity, required performance specifications, supplier authenticity, TDS, SDS, relevant certification or COA, availability, lead time, technical support, price and Total Cost of Ownership.

10. Why should Procurement and Maintenance evaluate lubricants together?

Maintenance understands equipment requirements and operating conditions, while Procurement understands suppliers, market pricing, availability, negotiation and commercial risk. Combining both perspectives produces stronger technical-commercial decisions.

Disclaimer: This article is intended for professional learning and general procurement awareness. Lubricant selection, substitution, mixing, drain intervals and application-specific decisions should be validated against the applicable OEM documentation, lubricant Technical Data Sheet (TDS), Safety Data Sheet (SDS), relevant standards and advice from qualified Engineering/Maintenance professionals.
