Categories of S.O.S analysis
Monitors wear by detecting, identifying and assessing the amount and type of wear metal elements in the oil. The rate at which wear metal particles increase from sample to sample is just as important as the quantity of particles in the oil. For this reason, regular sampling at specified intervals is necessary to establish wear rate trends for each oil-lubricated compartment. The presence of silicon and other elements which indicate dirt entry are also monitored with wear rate analysis.
Monitors any loss of the oil’s lubricating properties. An infrared analysis instrument is used to compare the properties of new oil to the properties of your used oil sample. This test allows our technicians to determine the extent to which the oil has deteriorated during use and to verify that the oil is performing up to it’s specification during the entire oil change period.
- Oil Cleanliness analysis
Uses a Particle Count test for non-engine oil. It detects both metallic and non-metallic debris (such as friction disc material) generated by wear, as well as dirt from outside sources. We will also provide a PQ (Particle Quantifier) test result which provides a measure of the amount of ferrous/magnetic material in the oil. This information, along with Wear Rate analysis, permits a comprehensive evaluation of your hydraulic and power train systems. This combination can detect potential failures not identified by Wear Rate analysis alone.
The presence of Fuel, Water or Glycol in oils are indicators of problems which may require immediate correction. Fuel dilution reduces the oil’s viscosity and destroys its lubricating properties. Glycol (from coolant) contamination causes rapid oxidation of the oil and will lead to a major engine failure if not promptly resolved. Water can contaminate an oil system by leaking in from the outside or by condensing within a hot oil compartment or engine crankcase. Water will cause the oil to form a sludge which can plug filters. Oil contaminated with water passing between close fitting moving parts will cause “hot spots” leading to reduced component life or rapid failure.
Our experienced Lab technicians will also perform a Visual Inspection of your oil sample, looking for any visible debris, obvious water or other contaminants and check with a magnet for larger metallic debris that can be indicative of serious problems within a compartment.
