Honda recommends using a high-quality 10W-40 motorcycle oil in the CBR400. The oil should meet or exceed the JASO MA/MA2 specification. Some popular choices include:
* Honda HP4 10W-40
* Castrol Power 1 10W-40
* Motul 5100 10W-40
* Repsol Moto Racing 10W-40
* Shell Advance Ultra 10W-40
Oil Capacity
The oil capacity of the CBR400 is approximately 2.5 quarts (2.4 liters). When changing the oil, it is important to drain the old oil completely and replace it with the correct amount of new oil.
Oil Change Interval
Honda recommends changing the oil in the CBR400 every 6,000 miles (10,000 kilometers) or once a year, whichever comes first. However, more frequent oil changes may be necessary if the motorcycle is operated in dusty or dirty conditions.
Oil Filter
The oil filter should be changed every time the oil is changed. Honda recommends using a genuine Honda oil filter, but there are also many aftermarket oil filters available that will fit the CBR400.
Checking the Oil Level
The oil level should be checked regularly, and topped up if necessary. The oil level should be between the "full" and "add" marks on the dipstick.
Changing the Oil
To change the oil, you will need the following tools:
* A new oil filter
* A new oil filter gasket
* A new oil drain plug gasket
* A funnel
* A wrench
* A drain pan
1. Warm up the engine for a few minutes to circulate the oil.
2. Place the drain pan under the oil drain plug.
3. Loosen the oil drain plug and allow the oil to drain into the pan.
4. Replace the oil drain plug and gasket.
5. Remove the oil filter and replace it with a new one.
6. Add the correct amount of new oil to the engine.
7. Start the engine and let it run for a few minutes.
8. Check the oil level and top up if necessary.
