Oil exchange
Oil exchange
The periodical engine oil exchange can expect the improvement of the fuel economy let alone keeping an engine smoothly by raising the efficiency of the engine. As for most of the engines of the recent fuel economy type-saving, designated low viscosity oil. This makes fuel economy better using the oil which is low (was cleared) of the viscosity not the oil which is expensive (muddy) of the viscosity by reducing frictional resistance with the oil. Please use low viscosity oil for a low viscosity oil designation engine to show original fuel economy performance-saving. I recommend the exchange every 3,000km - 5,000km run to keep the condition of the engine well. But about half once a year recommends that engine oil is changed when the mileage does not reach 5,000km. If an exchange cycle becomes long, oil deteriorates and can be going to give an engine damage even if I chose the high efficiency engine oil. In addition, the exchange of the oil element (filter) recommends what is changed to two times of oil exchange once.
