Category Component Test Kit Interval Comments
Engines Main Engines MAR 3 1 mon / 500 hr Test kit includes ferrography to closely monitor for abnormal wear, and TBN test to monitor the remaining alkalinity package in the oil.
  Auxiliary Engines MAR 2 1 mon / 500 hr Test kit includes TBN test to monitor remaining alkalinity in the oil.
  Diesel Generators MAR 1 1 mon / 500 hr MAR 1 kit for routine analysis, MOB 2 for extended drain interval testing (includes TAN test to monitor oil degradation).
Hydraulic Systems Power Packs MAR 2 2 mon / 1000 hr Includes Particle Count to monitor fluid cleanliness levels, and TAN to monitor fluid degradation.

  Coolant, Inhibitors COOL 12 mon / 3000 hr Test the condition of your coolant.
  Fuel FUEL every bulk shipment Test your bulk fuel shipments for contaminants and to verify fuel grade.
Special Sampling Considerations
Follow up on abnormal samples MAR 3 WearCheck advises that ferrographic analysis be performed with resamples on equipment that tested abnormal. Filter analysis allows the diagnostician to locate and detect major wear situations.
Extended oil drain interval testing MAR 2 Any equipment that is undergoing extended oil drain interval testing should use MAR 2 test kits. These kits include TAN testing to monitor the degradation of the oil, as well as the build up of acids in the oil. Oils with high TAN levels generally experience oil thickening, sludging, improper oil flow, and corrosion of components.
