Interpreting Oil Analysis Reports: What Do the Numbers Really Mean?

1.Viscosity: The Backbone of Lubrication-

How? The oil’s resistance to flow at specific temperatures
Why? Incorrect viscosity can lead to excessive wear, energy loss, or component failure.
What to do? Compare viscosity results to the OEM’s recommended range and investigate deviations promptly.

2.Contamination Levels: Detecting External and Internal Threats
How? Presence of water, dirt, fuel, or coolant in the oil.
Why? Contaminants accelerate wear, corrosion, and sludge formation.
What to do? Address contamination sources immediately—whether it’s improving seals, using better filtration, or fixing leaks.

3.Additive Depletion: Understanding Lubricant Longevity
How? The health of anti-wear, dispersant, detergent, and anti-oxidant additives
Why? Depleted additives mean oil can no longer protect against wear, deposits, or oxidation.
What to do? If additive levels are dropping too fast, consider adjusting oil change intervals or switching to a more durable lubricant.

4. Wear Metals: The Early Warning System for Equipment Failure
How? Presence of metals like iron, copper, aluminum, and lead from component wear.
Why? Elevated levels indicate abnormal wear, corrosion, or lubrication failure.
What to do? Compare wear metal trends over multiple reports rather than reacting to a single high reading. A sudden spike in metals demands urgent investigation.

5. Oxidation and Nitration: The Silent Killers of Lubricant Health
How? The chemical breakdown of oil due to exposure to oxygen and combustion gases.
Why? High oxidation leads to sludge, acidity increase, and thickened oil, reducing lubrication efficiency
What to do? If oxidation is high, investigate excessive heat sources and improve ventilation or cooling systems.
