This paper continues the study of the effect of chemical structure on friction and wear characteristics of base stocks in the four-ball wear tester. This study compares friction and wear properties of three vegetable oils and two synthetic esters based mainly on their chemical structure. The synthetic esters selected use oleic acid in their respective processing that yields products similar to vegetable oils. The vegetable oils chosen contain significantly different chemical structure or fatty acid compositions. The research includes blending of various additives to determine additive effectiveness in the different base stocks. To find the best linear regression model, the authors perform a best subset regression that also includes the oils in part 1. Finally, analysis of variance statistical methods evaluate oils from parts 1 and 2 to make final comments on chemical structure effects.
