The main objective of this paper is to investigate crude rubber seed oil (CRSO), a non-edible type of vegetable oil, hence thatcan be considered as a potential alternative fuel in Malaysia. The rubber seed production in Malaysia is about 150-200 kg/haper annum. The estimated availability of rubber seed is about 30,000 MT/year. At present, rubber seed oil has not been foundto be utilized in any major application. The challenge of the present study is to analyze the suitability and feasibility of rubber seed oil applied as biofuel, specifically in biogasoline range. Standard procedures of American Oil Chemists Society and ASTM Standard were used to determine the physicochemical properties of crude rubber seed oil (CRSO). Using standard techniques the specific properties data were obtained for this bio-oil namely for the following parameters: pH, specific gravity, refractive index, water content, peroxide value, acid value, kinematic viscosity, calorific value, density, molecular weight, flash point, cloud point, pour point, CHNS contents, saponification value, iodine value, and oxidative stability. Properties of rubber seed oil in comparison with standard biodiesel and other source of oils were also given. The observed values of this study were in agreement with the CRSO values of previous literature. The characteristic features of CRSO from this study show that CRSO can be exploited as an environmentally friendly alternative biofuel.
