AI Technical Summary
Technical Problem
Conventional lubricants lack the desired kinematic viscosity, viscosity index, and pour point, leading to reduced fuel efficiency and increased CO2 emissions.
Method used
A lubricant composition comprising a polyalphaolefin Type IV base oil component in the range of 30 wt.% to 70 wt.% and an alkoxylated polytetrahydrofurane of formula (I) in the range of 15 wt.% to 30 wt.% is used, which provides the necessary viscosity and friction modification properties.
Benefits of technology
The lubricant composition achieves improved fuel efficiency and reduced CO2 emissions by maintaining desired kinematic viscosity, high viscosity index, and low pour point, while also enhancing friction modification properties and shear stability.

Abstract
The present invention relates to a lubricant composition comprising a polyalphaolefin Type IV base oil component in an amount in the range of from 30 wt.% to 70 wt.% based on the total weight of the lubricant composition, and an alkoxylated polytetrahydrofurane of formula (I) in an amount in the range of from 15 wt.% to 30 wt.% based on the total weight of the lubricant composition. The present invention also relates to the lubricant composition that is used in an axle lubricant.
