After 10 hours, the engine oil should be replaced again. The oil will be changed regularly according to the instructions. The engine oil should be carried out under the heat engine condition. Oil can not be overloaded, otherwise it will appear: black smoke, lack of power (cylinder carbon deposition, spark plug clearance is small). Engine overheating. The injection oil can not be too small, otherwise it will be now: engine gear noise, piston ring accelerated wear and damage, and even now pull the phenomenon, causing serious damage to the engine.
