Basic Test Package for Engine Oil

Our Basic Test Package for engine oil is designed to determine and monitor: (1) lubricant properties, (2) contamination levels and (3) engine condition. This package is recommended for routine testing and analysis.

# Test Name Primary Test Method Units of Measure Sample Size (milliliters)
         
1 Spectrometric Elemental Analysis: ASTM D6595 Parts per million 60
  • Wear Metals      
  • Contaminant Metals      
  • Additive Metals      
2 Kinematic Viscosity @ 100° C. ASTM D445 Centistokes 30
3 Water Content ASTM D6304 % by volume 25
4 Fuel Dilution Fuel Sniffer % by volume 15
5 Soot Content Soot Meter % by volume  
6 Glycol Content ASTM D2982 Parts per million 20

Extended Drain Test Package for Engine Oil

Maintenance programs for large fleets typically call for changing the oil at regular intervals. If a primary objective of your oil analysis program is to maximize the useful life of the oil, however, we recommend our Extended Drain Test Package for engine oil.  

This package includes all of the tests in our Basic Test Package (above) plus Base Number (BN). As an indicator of the ability of the additive package to counteract acids, BN is used to determine the optimal interval for draining the oil from a diesel engine. As a general rule, an oil has reached the end of its useful life when the BN of the used oil is one-half of the BN specification of the new oil. Decreases in BN are usually accompanied by increases in viscosity.

Of course, this test package also provides the same information (on lubricant properties, contamination levels and engine condition) as the Basic Test Package (above).

Preventive Maintenance Test Package for Engine Oil

Our Preventive Maintenance Test Package for engine oil is designed to identify small problems in the engine before they become larger problems and ultimately cause catastrophic failure. This package includes all of the tests in the Basic and Extended Drain Test Packages (above) plus: (1) Oxidation by FT-IR; (2) Nitration by FT-IR; and (3) Particulate Analysis.  Depending on the situation, Particulate Analysis may consist of Particle Count (ISO 4406), Direct Read Ferrography (DRF), or both.

Predictive Maintenance Test Package for Engine Oil

Our Predictive Maintenance Test Package for engine oil is designed to predict engine failures before they occur. These predictions are based on the identification of the root cause of previous engine failures and the analysis of the trends that caused them. This package includes all the tests in the Basic, Extended Drain and Preventive Maintenance Test Packages (above) plus Analytical Ferrography.
