What is the oil capacity of the Honda CB400X?
2 Answers
The oil capacity of the Honda CB400X is approximately four liters. The engine operates under extremely harsh conditions, where engine oil plays a crucial role in lubrication, cooling, and cleaning the contaminants generated by engine friction, ensuring normal operation and prolonging the engine's lifespan. Therefore, engine oil is vital for the proper functioning and longevity of the engine. Notes: Choosing engine oil: Selection should be based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher demands. Choosing multi-grade oil: It is advisable to opt for multi-grade oil, as it is economical, long-lasting, and efficient, providing better protection for the engine. Due to the characteristics of multi-grade oil, it may appear darker earlier or exhibit lower oil pressure compared to conventional oil, both of which are normal phenomena.
When I first got my CB400X, I was also very concerned about this issue. The oil change capacity for this bike is 2.8 liters, but you don't actually need to fill it to the upper limit during maintenance. Every time I change the oil, I pour about 2.6 liters first, then start the engine and let it run for a minute. After turning it off and waiting for five minutes, I check the dipstick. When the engine is cold, the oil level should be slightly above the middle between the upper and lower marks on the dipstick—that's the ideal position. If you check the manual, you'll notice Honda specifically emphasizes this point—overfilling the oil actually increases crankshaft resistance, making the bike feel sluggish, and fuel consumption will also creep up. It's recommended to keep an extra half liter of oil when changing the oil filter, as some old oil will remain in the filter.
