By-Pass Oil Filter Test Two-Year Program

Abstract

This two-year oil filter test program was conducted to evaluate the effectiveness of by-pass oil filters in maintaining the cleanliness and lubrication qualities of the engine oil, during normal troop training operations. The engine oil characteristics for M939A1 trucks, with by-pass oil filters, were compared with the oil analysis characteristics of the used oil taken from similar M939A1 trucks which had only the standard full-flow oil filters. The engine oil samples which were obtained from the subject trucks at 60-day intervals, were given a laboratory analysis for the following: Wear-metal concentrations for following elements: copper, iron, lead and aluminum, the depletion of certain oil additives, oil viscosity measurements, concentrations of ferromagnetic particles (by average size), and the TAN & TBN values. Keywords: Oil additives, Contaminants, Wear metal concentrations, Viscosity, Dilution, Acidity, Basicity, Ferrograph Test. (js)
