The viscosity of vegetable oils palm oil in particular olein is 18 times higher than the viscosity of HSD. Whereas, the viscosity is allowable for the gas turbine engines which is around 0 to 10 CSt at the maximum temperature of 50 ˚C or when converted to the dynamic viscocity of about 0.78 to 780 mPa.s. In order to meet the gas turbine criteria, so that done the blending between the samples of HSD with PPO and then heated. From the blending of 95 % HSD – 5 % PPO at the temperature range of 30˚ - 35 ˚C were obtained the viscocity value with an average of 3,43 mPas. That results show that the viscosity value of the blending between HSD with PPO still meets the standards of eligibility as a gas turbine fuel.
