Abstract
In
a fresh and 14500 km used oil, viscosity, viscosity index, flash point, pour
point, specific gravity, color, total acid number, total base number, water
content, as well as concentrations of twenty four elements, were determined.
The mineral baesd, gasoline motor oil Speedy SL, from Sepahan Oil Company was
chosen for study. The physical properties were characterized by ASTM protocols.
The elemental analysis was performed by inductively coupled plasma- optical
emission spectroscopy (ICP-OES) . The results indicate that after the
application of fresh oil, both of the physical properties and elemental
concentrations have been changed significantly.
INTRODUCTION
Oil analysis (OA) is the sampling and laboratory analysis of a lubricant's
properties, suspended contaminants, and wears debris. OA is performed during
routine preventive maintenance to provide meaningful and accurate information
on lubricant and machine condition. By tracking oil analysis sample results
over the life of a particular machine, trends can be established which can help
eliminate costly repairs.
