Engine oil analysis to evaluate the degree of its wear during the period of operation of the vehicle

Abstract

The authors of this paper used samples of SAE 5W30 engine oil and analyzed the following parameters: viscosity, density, flash point, contamination with fuel and solids, degree of oxidation, dispersion power. The information on the evolution during the period of operation (considered post-warranty period) of these parameters is the basis for the elaboration of engine maintenance strategies considering the following three goals: the reliability, the operating costs of the vehicle and environmental issues.
