Standard Test: Diesel Engine oils
Diesel engines are the power units for your business and without power, all work stops. It is imperative to monitor wear, contamination and the oil’s properties to insure these engines do not fail prematurely. Unscheduled downtime is far more costly than the cost of repairs. Monitoring the condition of the fuel along with the oil puts all of the pieces of the puzzle together to tell a clear story. Choose the testing regime below that meets your maintenance and financial goals for your fluid analysis program
Elemental Metals (24) by ICP (or Spectroscopy)
Elemental Analysis, or Spectroscopy, identifies the type and amount of wear particles, contamination and additives. Determining metal content can alert you to the type and severity of wear occurring in the unit. Measurements are expressed in parts per million (ppm). It provides rapid screening of used oils for indications of wear.
Fuel Dilution % by Range in Viscosity confirmation by GC
A method for testing fuel dilution is gas chromatography (GC). In this method, the lubricating oil is injected directly into a GC according to ASTM D3524, ASTM D3525 or DIN 51380. The fuel dilution test is typically performed either when a significant drop in sample viscosity is measured, or when the flash-point test has failed.
Soot % by FTIR (Fourier Transform Infrared Spectroscopy)
The soot index is a linear measurement that measures the extent to which the oil has become contaminated by fuel soot, an unwanted by-product of combustion.
Total Base Number (TBN)
TBN measures the amount of active additive left in a sample of oil.
It determines how much reserve additive the oil has left to neutralize acids.
Base number testing is very similar to acid number testing except that the properties are reversed. The sample is titrated with an acidic solution to measure the oil’s alkaline reserve.
Water % by crackle of FTIR Viscosity @ 100°C
To detect the presence of water in lubricating oil.
