Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
If the engine is equipped with duplex oil filters, the engine oil filter elements can be changed while the engine is in operation. This is useful if the oil filter elements require more frequent replacement than the engine oil. Refer to "Replacing the Engine Oil Filters During Engine Operation (Duplex Oil Filter System Only)".The oil change interval can be affected by several factors:
Air/fuel ratio
Ambient air conditions
Engine application
Fuel type
Oil type
Size of the oil sumpThe S O S oil analysis program analyzes used oil in order to determine if the oil change interval is suitable for your specific engine.Drain the Oil
Do not drain the oil when the engine is cold. As the oil cools, waste particles settle on the bottom of the oil pan. The waste particles are not removed when the cold oil is drained. Drain the crankcase when the oil is warm. This method allows proper draining of the waste particles that are suspended in the oil.Failure to follow this recommended procedure will allow the waste particles to be recirculated through the engine lubrication system with the new oil.
After the engine has been operated at normal operating temperature, STOP the engine.
Drain the oil according to the equipment on the engine. Note: Drain the oil into a suitable container. DO NOT drain the oil into the bilge sump. Dispose of the oil according to local regulations.

Oil drain plug
Note: If a suction device is used in order to remove the oil from the oil pan, ensure that the suction device is clean. This will prevent dirt from entering into the oil pan. Be careful not to strike the engine oil suction tubes or the piston cooling jets.
If the engine does not have a drain valve or a pump, remove an oil drain plug. Allow the oil to drain. After the oil has drained, clean the drain plug and clean the fitting for the drain plug. Install the drain plug. Tighten the drain plug to 70 15 N m (52 11 lb ft).
If the engine has an oil drain valve, open the valve. After the oil has drained, close the valve.
If the engine has a pump for removing dirty oil, connect a hose to the outlet of the pump. Place the hose in a suitable container. Open the valve for the drain line. The two marks on the valve must be turned so that one mark points to the pump and the second mark points to the drain line. Operate the pump until the crankcase is empty. Close the valve to the drain line. Disconnect the hose.
If the oil drain valve has a “quick connect” coupling, attach the coupling. Open the drain valve in order to drain the crankcase. After the oil has drained, close the drain valve. Disconnect the coupling.
