Additives can make up 25% of an engine oil. We place close attention to additive concentration by element when analyzing these oils. We test for fuel dilution and examine certain wear metals unique to piston ring deterioration. Proper detergency capability is critical to engine oils and we monitor degradation over time.

Routine Testing for Engine Oils


Emission Spectroscopy Elemental Oil Analysis

  • MRT uses the Rotrode Spectrometer
  • We closely track changes in unwanted
    particles over time
  • Particle size detection down to 3 microns


  • We measure viscosity and viscosity index
  • At 40° C for industrial oils and 100° C for engine oils
  • Quantify severity of oil degradation and contamination
neutralization number

Neutralization Number

  • We measure Total Acid Number (TAN) and Total Base Number (TBN)
  • TAN detects oxidation and degradation and TBN
    detects remaining additives
Karl Fischer

Karl Fischer Water Titration

  • Water is the most common and arguably the most damaging oil contaminant
  • We detect water down to 4 ppm in any state
flash point

Flash Point of Lubricating Oil

  • Testing for contaminants, commonly infiltrating through seal leaks
  • An irregular flash point indicates contamination
fourier transform infrared

Fourier Transform InfraRed (FTIR) for Oil Oxidation

  • Quantifies water, glycol, soot, fuels, and also oxidation and nitration by-products present in lubricants
direct read ferrography

Direct Read Ferrography

  • Measure cleanliness by counting large and small
    magnetic particles
  • Total amount and relationship of small to large
    particles can indicate issues with machinery
