Used Oil Analysis reflects:

Categories of used oils analyzed:

Oil analysis is essential for assessing the health of equipment operation.

A sample of oil provides crucial information that can help:

 

  • Increase productivity

  • Reduce unscheduled downtime

  • Improve equipment durability

  • Lessen lubricant consumption  

  • Assess condition of the oil

  • Evaluate condition of the equipment

  • Improve the environment in which the equipment operates

  • Overall, save money and time

  • 4-stroke engine oils

  • CODA (2-stroke engines oils)

  • Hydraulic oils

  • Turbine oils

  • Gear oils

  • Thermal oils

  • Other types of industrial oils

Viscometrics

  • Kinematic Viscosity @100°C & @40°C i.a.w. ASTM  D7042

  • Viscosity Index i.a.w. ASTM D2270

Increase of Viscosity:

  • Oxidation

  • High Contamination (wear metals /soot)

Decrease of Viscosity:

  • Oil Consumption

  • Fuel Dilution

  • VM Degradation

Total Base Number – TBN:

  • ASTM D 2896

  • Monitor the remaining alkalinity of over based detergent additives

Increase of TBN:

  • Oil Consumption

  • High Temperature

  • Too low Viscosity

Decrease of TBN:

  • Fuel Dilution

  • Fuel Quality

  • Too long drain period

Total Acid Number – TAN:

  • ASTM D 664

  • Monitor the oxidative degradation of an oil.

 

Increase of TAN:

  • Oil degradation

  • High acid concentration in oil

Flash Point:

  • ASTM D 93

  • Detects flashpoint of lubricant

  • Lubricants are estimated to have a flashpoint above 190 °C 

​

Decrease of flashpoint:

  • It’s possible that there is a fuel leak.

Water Content:

  • ASTM D 6304

  • Determination of water content in lubricants

​

Increase of water content:

  • Indicates that there is water inflow in the system.
