SGM National Lab
Oil Analysis Lab in India
Lubricating oil keeps engines, turbines, compressors, and machinery running — until it doesn't. Oil degrades, picks up contamination, and loses its protective properties over time, often before there's any visible sign of trouble. SGM National Laboratory is an Oil Analysis Lab in India that tests industrial and lubricating oils to catch degradation early, helping manufacturing plants, transport fleets, power stations, and mining operations plan maintenance before a failure happens instead of after.
Why Oil Analysis Matters in India
An oil sample carries information about the equipment it came from, not just the oil itself. Wear metals in the oil can indicate which components are wearing down, while contamination may point to seal, filter, or handling problems. Additive depletion can show how much protective life remains in the oil. An Oil Analysis Lab in India can review these results together to provide a clearer picture of equipment condition. Regular oil analysis helps identify developing problems early, allowing maintenance teams to plan corrective action before minor issues become costly failures, unexpected repairs, or unplanned shutdowns.
What We Test in Oil and Lubricant Samples
Our oil and lubricant testing covers key properties related to oil quality, condition, contamination, and performance. At our Oil Analysis Lab in India, we test viscosity, density, moisture, flash point, pour point, TAN, TBN, oxidation, nitration, additives, and wear metals. Testing supports quality control, condition monitoring, maintenance planning, and reliable lubricant evaluation.
Viscosity Testing
Measures an oil’s resistance to flow and helps assess its lubricating performance. Testing identifies changes in oil thickness that may affect lubrication, component protection, operating efficiency, and overall equipment performance.
Wear-Metal Analysis
Detects trace metals such as iron, copper, aluminium, and chromium in used oil. The type and concentration of wear metals can indicate internal component wear and help identify developing equipment problems.
Contamination Testing
Identifies contaminants such as dirt, dust, water, coolant, and fuel dilution in oil. Testing helps assess contamination levels that may reduce lubricant performance, increase wear, and affect equipment reliability.
Oxidation & Nitration Testing
Measures oxidation and nitration products formed during oil service. These indicators help evaluate lubricant degradation caused by heat, air, and combustion byproducts and support decisions about oil condition and replacement.
Additive Depletion Analysis
Evaluates changes in lubricant additives that provide protection against wear, oxidation, corrosion, and deposits. Testing helps determine additive condition and identify changes that may affect oil performance during service.
Moisture Content Testing
Measures the amount of water present in an oil sample. Excess moisture can reduce lubrication performance, promote corrosion, accelerate oil degradation, and contribute to equipment wear or operating problems.
Total Acid Number
Determines the acidic content of an oil and helps monitor oxidation and lubricant degradation. Increasing TAN values can indicate chemical changes in the oil and support timely maintenance or replacement decisions.
Total Base Number
Measures the remaining alkaline reserve in lubricating oil, particularly engine oils. TBN testing helps assess the oil’s ability to neutralize acidic compounds and indicates changes in protective capacity during service.
Pour Point Testing
Flash point indicates the temperature at which oil vapours can ignite, while pour point shows low-temperature flow behaviour. Testing helps evaluate handling, storage, safety, and suitability for operating conditions.

What We Evaluate in Oil Analysis
Oil analysis goes beyond checking if oil “looks fine.” At SGM National Laboratory, an Oil Analysis Lab in India, we test oil and lubricant samples to reveal what’s happening inside the equipment they came from — degradation, contamination, and wear that aren’t visible by eye. This supports predictive maintenance, cost control, and equipment longevity across industries relying on engines, turbines, compressors, and hydraulic systems. We evaluate key characteristics, including:
| Parameter | Why It Matters |
|---|---|
| Viscosity | Determines whether oil is within its intended thickness range to lubricate and protect moving parts effectively. |
| Wear Metal Content | Detects trace metals like iron, copper, and aluminium that indicate which internal components are wearing down. |
| Water Content | Identifies moisture contamination, which accelerates corrosion and reduces lubricating performance. |
| Fuel Dilution | Measures fuel contamination in engine oil, which thins the oil and reduces its protective properties. |
| Oxidation Level | Assesses breakdown caused by heat and air exposure, indicating how much useful service life the oil has left. |
| Nitration Level | Measures combustion byproduct buildup, relevant mainly to engine oils operating under high thermal load. |
| Additive Depletion | Checks whether protective additive packages are still active or have been used up during service. |
| Particle Contamination | Detects dirt, dust, and solid debris that accelerate component wear and can clog filters or narrow passages. |
