Abstract

The requirements of ecofriendly lubricants has become a concern today as alternatives to the mineral-based lubricant due to its effect to the environment. This is because of the earth impact forces by mineral-based oil making the impact of substitution to be fundamental. This study is focused on created polyol as lubricant additives to hydraulic lubricants. To lead this analysis, the effect of polyol to viscosity index increases the viscosity of lubricant using Viscometer according to (ASTM D445). After that, to know the TAN using Titration Acid Number according to (ASTM D664). Then, the wear and preventive quality of the lubricant were obtained by utilizing a four-ball tester according to (ASTM D4172) with the same loads and speeds. The wear scar breadth of the balls using SEM according to (ASTM E986) was estimated utilizing an optical magnifying lens and the wear component additionally had been considered. When the analysis had been done, sample number 3 is the optimum result which is 7.5% polyol because of the good viscosity index, total acid number, and coefficient of friction compared to another sample. It shows that the polyol as lubricant additives is potentially being used in transmission. This is because of the coefficient of friction of the polyol as lubricant additives are in boundary lubrication regime and the wear preventive characteristic shows good performance to withstand the load and speed
