Forensic Discrimination of Fake and Genuine Mobil Oils

Abstract

The major functions of lubricating oils is the reduction of friction and wear by the separation of surfaces, metallic or plastic, which are moving with respect to each other. The few Indian infringers are engaged in cheating, substandard and duplication cases forensic scientist and police facing problems with rapid increase in different types of Mobil oils having hydrocarbons and other additives. Which can be used for comparison purpose keeping in this view a protocol for rapid screening and analysis of these type of material by using physical parameters, thin layer chromatography and FT-IR spectral analysis have developed to differentiate fake (used) Mobil oil and genuine unused branded Mobil oils. The present work describes the discrimination of fake and genuine Mobil oils on the basis of physical parameters, thin layer chromatography and FT-IR analysis.
