The development of the automotive world today most motorcycle users want a good performance and powerful engine, on the 2-stroke engine has advantages in the amount of torque and power obtained on the engine speed. The importance of side oil on the 2-step motor is to reduce friction on the engine components, reduce noise, cooling, and as seals. The burning side oil with fuel and air will affect motor performance. The number of sorts and brands of side oils to confuse someone to choose which side of the oil is right to improve engine performance. This experiment aims to determine the effect of using 3 side oil on the performance of Kawasaki Ninja RR 150 cc motor. To know the influence on each of the spark plugs need to be tested. Testing is done using premium fuel and this test is performed to look for engine performance which includes Torque, Power and fuel consumption. The results of this study indicate that the best viscosity value is found in 2T Sport Mesrania oil. While the highest torque and power value is in the oil Ultraline Racing 2T with a torque of 19.79 N.m at 8233 rpm engine speed and power value of 24.7 Hp at 9388 rpm engine speed. Next on the test of fuel consumption of spark plug that consumes the least fuel is Shell Advance SX 2T with a value of 20.87 km/l with an average speed of 34.28 km / h.
