In the study, seventeen qualified preservative oils were investigated to establish their lubricity properties. The oils were tested in a Shell Four-Ball Wear Tester at selected loads and the wear scars measured. The viscosity and acidity of each oil were determined before and after wear test. Adhesive wear particles formed during wear tests were examined microscopically and their size shown to be an indication of the lubricating ability of the oil. Results indicate that these oils leave considerable room for improvement in their lubricating ability. A new method, using thermometric titrimetry, was developed for determining acidity in new and used corrosion preventive and lubricating oils. The total acid numbers obtained by colorimetric, potentiometric, and thermometric methods were compared. Author
