Higher energy-conserving engine oils are becoming important in the face of the saving of natural resources. When it comes to energy-conserving engine oil, we consider low viscosity oil with special additives like friction modifiers.In this research, the effect of viscosity was studied, especially HTHS (High Temperature High Shear) viscosity on friction reduction. Then the best oil for friction reduction was used to learn how such oils work on friction reduction with different FM (Friction Modifier). We have used two types of FM, organic and inorganic, because of different friction reduction mechanisms.Our study of FM treated low viscosity engine oil has been continued to evaluate how such oils work at different part in the engine. Through the friction test, engine friction and engine friction without head (cam) was measured. Then, the effect of each FM on friction reduction at different engine parts was also studied.Finally, from the vehicle test for fuel economy, we also found that the relation between friction at non-firing friction tester (NFFT) and fuel economy test using passenger car.
