Oil capacity (Guideline): 4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only a guideline. The necessary quantity of oil depends on the quantity of oil that has been drained.
The quantity of drained oil differs slightly depending on the tempera-
ture of the oil and the time the oil is left flowing out. After refilling the
engine with oil, therefore, you must use the dipstick to confirm that the
level is correct.
14. Start the engine and make sure that no oil leaks appear aroundthe filter ’s rubber seal and drain plug.
15. Run the engine until it reaches the normal operating temperature.
Then stop the engine and wait a few minutes to allow the oil drain
back. Check the oil level again and if necessary, add more engine oil.   Recommended grade and viscosity CAUTION
Use only engine oil with the recommended grade and viscosity.
Oil grade: ILSAC GF-3, which can be identified with the new API certification mark (Starburst mark) 
or API classification SL with the words  “ENERGY CON-
SERVING”  (if you cannot obtain the oil with SL grade,
you may use SJ grade  “ENERGY CONSERVING ” oil).
These recommended oil grades can be identified by looking for either 
or both of the following marks displayed on the oil container.

Air cleaner element
WARNING
Do not operate the engine with the air cleaner element removed.The air cleaner element not only filters intake air but also stops
flames if the engine backfires. If the air cleaner element is not
installed when the engine backfires, you could be burned.
The air cleaner element functions as a filter screen. When the element is
perforated or removed, engine wear will be excessive and engine life
shortened. 
The air cleaner element is a viscous type. It is unnecessary to clean or wash the element.
