Used Oil Analysis

Changes in the appearance of the zones or bands are a clear indication that something in the lubricant has changed. A closer look at the zones, their unique formation and the debris fields contained therein may indicate an increased level of contaminants, additive depletion, breakdown of fluid, viscosity changes, etc.

The instant analysis chromatography technique is not limited to any type of fluid, notes Wohlwend.

It can handle brake fluids, power steering fluid, automatic and manual transmission fluids, gear oils, crankcase oil, synthetic and petroleum-based fluids and oils alike, says McElroy. There is even technology that provides diagnostics for all formulations of antifreeze and coolants.
