Oil Testing Laboratory for Fresh and Used Lubricants
Oil testing laboratory in India for fresh and used lubricants, with sample coordination through Chem-Tech's laboratory facilities in Pune, Maharashtra.
- Fresh & used oilsQuality, condition and investigation scopes
- ASTM, ISO, IP & IS methodsApplicable methods confirmed with the scope
- Reports with contextResults reviewed against the right reference
Start with your maintenance question
The useful test is the one that supports a decision.
Oil testing can assess the lubricant itself, contaminants entering the system and material associated with equipment wear. These are connected—but they are not the same question.
Chem-Tech helps customers choose a relevant scope for fresh-oil verification, routine used-oil monitoring, troubleshooting or a focused investigation. Supplying the equipment and operating context makes the result more useful.
What do you need to know?
Choose your oil-testing objective
02
Contamination investigation
Investigate water, fuel, soot, dirt, particles or mixed-fluid concerns affecting the oil or equipment.
03
Fresh oil verification
Check selected properties of new, delivered or stored oil against an agreed specification or reference sample.
04
Equipment fault investigation
Review wear-related evidence with the component, oil grade, operating history and symptoms supplied by your team.

→06Compressor oil
Air, gas and refrigeration compressor applications.
→Understand the laboratory scope
What common oil tests can reveal
Not every sample requires every parameter. The final scope depends on the oil, application, available sample quantity and purpose of testing.
01
Oil condition
Shows whether the lubricant has changed, degraded or may no longer be suitable for continued service.
- Kinematic viscosity
- Viscosity index
- Total acid number (TAN)
- Total base number (TBN)
- FTIR oxidation / nitration
- Flash point
02
Contamination
Helps identify unwanted material entering or developing within the lubricant system.
- Water content
- Particle count / ISO 4406
- Fuel dilution
- Soot
- Insolubles / sediment
- Contaminant elements
03
Wear evidence
Examines material associated with component wear and should be read with equipment metallurgy and history.
- Elemental analysis
- Wear metals
- PQ index
- Analytical ferrography
- Wear-debris examination
- Trend comparison
04
Application performance
Additional tests selected for the oil type, system design and operating concern.
- Foaming tendency
- Water separability
- Oxidation stability
- Membrane patch colorimetry
- Air release
- Application-specific properties
From question to action
How to get a useful oil-testing result
Representative sampling and complete asset information are as important as the laboratory measurement.
Read oil sampling guidance- 01
Tell us the decision you need to make
Routine monitoring, troubleshooting, fresh-oil verification and contamination investigations require different test scopes.
- 02
Identify the oil and equipment
Share the lubricant name and grade, asset, component, oil hours, equipment hours and recent maintenance history.
- 03
Collect a representative sample
Use a clean bottle and a consistent sampling point. Avoid stagnant zones, drain bottoms and contaminated containers.
- 04
Confirm the laboratory scope
Chem-Tech confirms the parameters, methods, sample quantity and reporting requirement before testing.
- 05
Review the result in context
Compare the findings with the correct specification, fresh-oil baseline, previous trend and operating condition.
Before sending the sample
Information that improves interpretation
Label the bottle clearly and provide enough context for the laboratory to understand what the sample represents.
Sample identification
Tell us what the oil came from
- Asset, component and sampling point
- Lubricant brand, product and viscosity grade
- Fresh oil or in-service oil
- Oil hours, equipment hours and sampling date
- Top-ups, oil changes, filtration and recent repairs
Reason for testing
Tell us what decision is pending
- Routine monitoring or baseline creation
- Abnormal noise, temperature or pressure
- Suspected water, fuel, dirt or mixed oil
- Oil-change, filtration or maintenance decision
- Specification, warranty or incoming-quality check
For fleets, plants and critical assets
Turn repeat samples into an Oil Condition Monitoring programme.
Standardise asset details, sampling points, test groups and intervals so developing condition, contamination and wear patterns are easier to identify.

Questions before you submit a sample
Visit the FAQ centreWhich oil tests should I select?
The correct test set depends on the oil, equipment and decision you need to make. Share the application and concern; Chem-Tech will help define a relevant scope rather than applying the same package to every sample.
How much oil sample is required?
Sample quantity depends on the selected tests. Confirm the scope before dispatch so the laboratory can advise the required bottle type and volume.
Can one result confirm equipment failure?
A single result may identify an abnormal condition, but it should be reviewed with sampling quality, operating information, maintenance history and previous results. Trend data usually provides stronger evidence.
What details should accompany a used-oil sample?
Provide the asset and component ID, lubricant grade, oil and equipment hours, sampling point and date, top-ups, oil changes, filtration or repairs, and the reason for testing.
Do you test both fresh and used oil?
Yes. Fresh-oil testing can support quality or specification checks, while used-oil analysis assesses changes during service. The parameters and interpretation basis are different.
Fresh and used oil testing
Select evidence for quality, contamination, wear and performance
Oil testing should be matched to the lubricant, equipment and decision required. A fresh-oil check, routine condition sample and failure investigation use different parameters, references and interpretation context.
Fresh-oil verification
Check selected delivered, stored or reference-oil properties against an agreed basis.
In-service condition
Assess changes in lubricant properties alongside oil hours, equipment hours and maintenance history.
Contamination and wear
Investigate water, particles, fuel, soot, mixed fluids and wear-related evidence.
Application-specific scope
Add performance parameters relevant to engine, hydraulic, gear, turbine, compressor or other systems.
