Abstract

The effects Of additive formulations namely Hexagonal Boron Nitrate (hBN) on the viscosity index of lubricating oils (base oils) namely 20W40 temperatures 30 to 90 were investigated. The base oils were blended with the additives in different proportions. The results gave a viscosity index of 96 and 98 respectively for 20W40 without additives and with additives. The results revealed that 261 additive formulations gave the highest increase in viscosity in all proportions increasing as the weight of the additive increases. Generally, all the four additive formulations used improved the viscosities of all the blends in all the proportions and at both temperatures. The blends can be classified as very high viscosity index being above 110. This means that they will undergo very little change in viscosity with temperature extremes and so can be considered to have stable viscosity.
