The Fluid-Science Report Card, No. 95120-G, by Fluid Rx Diagnostics, was developed for BMW, Mini, Mercedes, Audi, Porsche, Range Rover and Volkswagen dealerships and their specialty fluids including Pentosin Power steering, CVT fluids, brake, ATF and gear oils. All modern lubricants contain additives that help inhibit breakdown. As these additives are depleted, sludge is formed. One drop of sample fluid is placed on the test sheet and as the fluid percolates through the unique filter paper, bands of different hues and densities form a chromatogram. 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 reveals high particle-counts that can be correlated to ISO Code.
