17623-ZV0-000 Honda SPONGE, FUEL CAP BREATHER (Honda Code 1814763).

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 sump

Engine Oil Change Intervals    
Engine Configuration     Interval    
Standard     1000 Hours or 1 year    
25 degree tilt     500 Hours or 1 year    The S O S oil analysis program analyzes used oil in order to determine if the oil change interval is suitable for your specific engine. In the absence of S O S oil analysis, change the engine oil and filters according to the oil change interval.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.

(1) Oil drain valve (2) Oil drain plugNote: If a suction device is used in order to remove the oil from the oil pan, ensure that the suction device is clean. This process 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 145 15 N m (105 10 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. 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.
Replace the engine oil filter elements before filling the crankcase with new oil.Replace the Oil Filter Elements
Replace the engine oil filters when any of the following conditions occur:
Every scheduled oil change
Every year
The differential pressure of the engine oil filter reaches 100 kPa (15 psi).Note: Do not attempt to clean the used oil filters. Used oil filters will retain waste particles. The used oil filters would not filter the oil properly.Service tools are available to aid in the service of oil filters. Consult your Cat dealer for the part names and the part numbers. Follow the instructions that are supplied with the service tools. If the service tools are not used, perform the procedures listed below.Illustration 6 identifies the drain valves and respective drain housings. The filter drain housings are identified by "1" and "2" which are cast into the drain housing.Replacing the Engine Oil Filters With the Engine Stopped
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
Note: Use the following procedure if the engine oil filter is equipped with or without a control valve when the engine is stopped.Perform the following procedure after the oil has been drained.

Note: Connect a suitable oil drain hose to the oil drain valves (2) before opening the oil drain valves. Drain the oil into a suitable container. Dispose of the oil according to local regulations.
Open the drain valves (2). Allow the oil to drain.Note: Some oil will remain in the housing after the oil has been drained. This oil will pour out of the housing when cover (2) is removed. Prepare to catch the oil in a suitable container. Clean up any spilled oil with absorbent pillows or towels. DO NOT use absorbent particles to clean up the oil.
Personal injury can result from parts and/or covers under spring pressure.Spring force will be released when covers are removed.Be prepared to hold spring loaded covers as the bolts are loosened.
Be alert to the spring force. Gradually loosen but do not remove bolts (1). Before removing the bolts, pry cover (2) loose or tap the cover with a rubber mallet in order to relieve any spring pressure.
Remove cover (3), O-ring seal, spring (4), retainer (5), and wire rack (6). Remove oil filter elements (7) .
Clean cover, spring (4), O-ring seal, and retainer (5). Clean the inside of the oil filter housing.
