Study on variation of tribo‐performance of commercial engine oils
Abstract
Purpose
The purpose of this paper is to study the performance variability of the commercially available engine oils based on physico‐chemical and tribological performance parameters.
Design/methodology/approach
The study does this by evaluation of physico‐chemical parameters of flash point, pour point, TAN, sulphated ash, viscosities @ 40 and 100°C and VI; and the tribological performance in terms of friction, wear, weld load and the load bearing capacity of the lubricant film under the point and line contact geometries.
Findings
Correlation between some of the physico‐chemical properties and tribological performance parameters could be made and the variation in performance of the lubricants assessed.
Originality/value
The findings will be important to the engine oil producers and the users.
