Lubricant is a substance used to reduce friction between surfaces, reduce the heat generated from moved surface. Regarding to the increasing of the price of base oil extracted from crude oil and to protect the environment from pollution although the depletion of crude oil, we searching for alternative bio source. A bio lubricant is renewable and nontoxic source for base oil, the objective of using Jojoba as base oil to get renewable source and solve environmental issues. Jojoba Oil used in a variety of products including pharmaceuticals, cosmetics, lubricants and bio-fuel. In this study was successfully use base oil come from Jojoba seed. The extracted oil was modified to be bio-lubricant. There is analysis done regarding to the chemical and physical properties such as density, pour point, flash point as well as viscosities at 40 and 100oC and viscosity index for the base oil and bio lubricant, although there is comparison done with the characteristics of a mineral lubricant (Hydraulic oil SAE 10W). The result of the analysis revealed that Jojoba oil has high viscosity index (247.9) and pour point of (9 oC), also has a flash point of (150 oC), Viscosity @40 c (22.51 Cst), Viscosity @100 c (6.16 Cst), and density @15c (0.8640). The result from jojoba lubricant has good specification in term of commercial standards for 10 W products with engine additive all result in the range, bio lubricant has high flash point (238 oC), viscosity index (242.2), lubricity, and low pour point of (5 oC), also has a flash point of higher than the characteristic of the commercial lubricant, high viscosity index (397), and low pour point of (5 oC). It was found that the bio-lubricants produced were comparable to the commercial standards for Hydraulic oil SAE 10W lubricant.
