Differentiation of Automotive and Locomotive Lubricant Oil

CODEN: JFSCAS

Abstract

Migratory waterfowl can confuse open oil pits for freshwater ponds. These open pits lead to waterfowl death. Frequently the pits contain oil and waste lubricant oil from automotive or locomotive origin. Automotive lubricant oil contains zinc dithiophosphate, a detergent and dispersant chemical additive. Locomotive lubricant oils do not contain zinc dithiophosphate. A GC-MS and XRF technique is presented that allows for the characterization of used lubricant oil as to being from automotive of locomotive sources. Identification of the oil source aids in the prosecution of open oil pit owners.
